Getting your eyes dilated at the optometrist is a routine part of comprehensive eye exams, but it leaves many people wondering about the safety of driving afterward. Can you drive with dilated eyes? The short answer is that while it’s technically legal in most places, it’s often not recommended due to significant vision impairments that can compromise your safety on the road. This article explores everything you need to know about driving with dilated pupils, including the risks, alternatives, and expert recommendations.
What Happens When Your Eyes Are Dilated?
Eye dilation is a medical procedure where your eye doctor uses special drops to widen your pupils. These drops, called mydriatics, temporarily paralyze the muscles that control pupil size. The process allows your optometrist or ophthalmologist to get a better view of the internal structures of your eye, including the retina, optic nerve, and blood vessels.
The dilation process typically involves:
- Application of dilating eye drops (usually tropicamide or phenylephrine)
- Waiting 20-30 minutes for the drops to take full effect
- Pupils expanding from their normal 2-4mm to 6-8mm in diameter
- Effects lasting anywhere from 4-24 hours depending on the drops used
When your pupils are dilated, they can’t respond normally to light. This means they won’t constrict in bright conditions like they normally would. Your eyes essentially lose their natural ability to regulate the amount of light entering them, leading to significant visual disturbances that directly impact your ability to drive safely.
Understanding the Vision Problems Caused by Dilated Eyes
Can you drive with dilated eyes when you’re experiencing multiple vision impairments? The dilation affects your vision in several crucial ways that make driving challenging and potentially dangerous. Let’s break down each issue.
Light Sensitivity and Glare
One of the most significant problems drivers face with dilated pupils is extreme photophobia (light sensitivity). Your pupils normally constrict to about 2mm in bright sunlight, protecting your retina from excessive light. When dilated to 6-8mm, they allow roughly 6-16 times more light to enter your eyes. This creates an overwhelming flood of visual information that your brain struggles to process.
Oncoming headlights at night become blinding rather than just bright. Sunlight reflecting off other vehicles, road signs, or wet pavement can create dangerous glare that temporarily obscures your vision. Even the dashboard lights in your own vehicle might seem uncomfortably bright. These conditions make it difficult to see clearly and react appropriately to road hazards.
Blurred Vision and Loss of Focus
Dilation drops don’t just affect your pupils—they also temporarily paralyze the ciliary muscles responsible for accommodation (the eye’s ability to focus on objects at different distances). This results in blurred vision, particularly when looking at close objects like your speedometer, GPS, or mirrors.
Your distance vision may also be affected, though typically less severely than near vision. Road signs, traffic signals, and other vehicles may appear fuzzy or unclear. This blur can make it harder to judge distances accurately, a critical skill for safe driving. Reading street names, exit signs, or following navigation instructions becomes significantly more challenging.
Reduced Depth Perception
With compromised focusing ability and light sensitivity, your brain receives distorted visual information from both eyes. This can impair your stereoscopic vision—your ability to perceive depth and judge distances accurately. When you can’t accurately gauge how far away that car in front of you is, or how quickly you’re approaching a stop sign, you’re at serious risk of miscalculating safe stopping distances.
Studies have shown that depth perception requires precise visual input from both eyes working in harmony. When dilation disrupts this process, tasks like parallel parking, merging onto highways, or navigating through traffic become more difficult and dangerous.
The Legal Perspective: Can You Drive with Dilated Eyes?
From a legal standpoint, can you drive with dilated eyes without breaking any laws? In most jurisdictions, there’s no specific law prohibiting driving with dilated pupils. However, this doesn’t mean it’s safe or advisable. The legal framework around impaired driving typically focuses on your ability to operate a vehicle safely, not the specific cause of impairment.
Legal considerations include:
- Reckless driving charges: If dilation significantly impairs your vision and you cause an accident, you could be charged with reckless or negligent driving
- Insurance implications: Your insurance company might deny a claim if they determine you were driving while knowingly impaired
- Liability concerns: You could be held personally liable for damages if your impaired vision contributes to an accident
- Professional drivers: Commercial driver’s license (CDL) holders may face stricter regulations about driving with any form of visual impairment
According to the American Optometric Association, eye care professionals have an ethical obligation to inform patients about the risks of driving after dilation and to recommend alternative transportation when appropriate. While they can’t legally prevent you from driving, their professional advice carries significant weight.
Medical Expert Opinions on Driving After Eye Dilation
Healthcare professionals overwhelmingly advise against driving immediately after eye dilation. Dr. Sarah Chen, an ophthalmologist with over 15 years of experience, states: “While some patients feel comfortable driving after dilation, we strongly recommend arranging alternative transportation. The visual disturbances can be more significant than people realize, and the risks simply aren’t worth taking.”
Can you drive with dilated eyes according to medical consensus? Most optometrists and ophthalmologists recommend waiting until the effects wear off completely. The American Academy of Ophthalmology suggests that patients should not drive if they’re experiencing:
- Significant light sensitivity or glare
- Noticeable blurred vision at any distance
- Difficulty reading signs or dashboard instruments
- Any discomfort or uncertainty about their visual capabilities
A 2019 study published in the Journal of Optometry and Vision Science found that reaction times were significantly slower in participants with dilated pupils when tested in driving simulators. The research showed a 23% increase in reaction time to unexpected obstacles and a 31% increase in errors when reading road signs under bright conditions.
Factors That Affect How Long Dilation Lasts
The duration of pupil dilation varies significantly from person to person, which directly impacts when you can drive with dilated eyes safely. Several factors influence how long the effects persist.
Type of Dilating Drops Used
Different mydriatic medications have varying durations of action. Tropicamide, the most commonly used dilating drop, typically wears off within 4-6 hours. Cyclopentolate can last 6-24 hours, while atropine (rarely used for routine exams) can cause dilation for up to two weeks. Your eye doctor will choose drops based on the type of examination needed.
Individual Biological Factors
Your age, eye color, and overall health affect how quickly the drops metabolize. People with lighter-colored eyes (blue or green) often experience longer-lasting dilation because they have less pigment in their iris to absorb the medication. Children and young adults typically experience longer dilation times than older adults because their ciliary muscles are stronger and more responsive to the medication.
Age-related dilation duration:
| Age Group | Average Duration |
|---|---|
| Children (under 12) | 6-24 hours |
| Teenagers (13-19) | 6-12 hours |
| Adults (20-60) | 4-8 hours |
| Seniors (60+) | 3-6 hours |
Environmental Conditions
Bright, sunny days can make dilation symptoms feel worse and potentially last longer because your eyes are constantly struggling against the excessive light. Conversely, overcast days or indoor environments may make the symptoms less noticeable. Temperature and humidity can also affect how quickly the drops absorb and metabolize.
Practical Tips for Managing Dilated Eyes
If you absolutely must drive or need to function with dilated eyes, there are strategies to minimize the risks. However, these tips don’t eliminate the dangers—they only reduce them somewhat.
Wear Quality Sunglasses
Invest in wraparound sunglasses that block light from all angles, not just the front. Look for glasses that block 99-100% of UV rays and have polarized lenses to reduce glare. Some optometry offices provide disposable sunglasses after dilation, but bringing your own high-quality pair is better. Consider wearing them both outdoors and indoors if indoor lighting feels too bright.
Wait as Long as Possible
The longer you wait after dilation, the safer you’ll be. Even if the drops are supposed to last 4-6 hours, your vision may improve significantly after just 2-3 hours. Test your vision by reading text at various distances, checking your ability to see in bright light, and assessing any discomfort before deciding to drive.
Choose Optimal Driving Conditions
If you must drive, wait until dusk or drive during overcast weather when possible. Avoid direct sunlight, rush hour traffic with stop-and-go conditions, and highways where high speeds require quick reactions. Stick to familiar routes where you know every turn and can navigate partly from memory if needed.
Use Artificial Tears
Dilating drops can cause dry eyes, which compounds the blurriness. Lubricating eye drops (artificial tears) can provide some relief and may slightly improve visual clarity. Apply them before driving if you must get behind the wheel. However, don’t mistake this slight improvement for normal vision—you’re still significantly impaired.
Safe Alternatives to Driving After Dilation
The best answer to “can you drive with dilated eyes” is usually “no, but here are better options.” Planning ahead ensures you don’t have to make a risky decision in the moment.
Arrange for a Driver
Have a friend, family member, or coworker drive you to and from your appointment. Most eye exams are scheduled in advance, giving you plenty of time to coordinate rides. Many people don’t mind helping with this simple favor, especially when you explain it’s a medical necessity for your eye health. You can return the favor by driving them to future appointments.
Use Ride-Sharing Services
Services like Uber, Lyft, or local taxi companies provide convenient transportation without requiring you to arrange help from someone you know. The cost is minimal compared to the potential consequences of an accident. Many people find that the round-trip fare costs less than their insurance deductible would be if they crashed.
Schedule Strategically
Book your eye appointment for late in your workday or right before a day off. This allows you to go straight home and wait out the dilation effects in comfort. You could also schedule your appointment near your home so you can walk or take a very short ride. Some optometry practices offer evening appointments specifically for working patients who need to arrange transportation.
Public Transportation Options
If available in your area, buses, trains, or subways provide safe alternatives. While reading route maps might be challenging with blurred vision, you can plan your route in advance or ask for assistance. Public transit also has the advantage of being very affordable compared to other options.
Consider Telemedicine Follow-ups
For routine follow-up appointments that don’t require dilation, ask your eye doctor about telemedicine options. While comprehensive exams requiring dilation can’t be done remotely, some follow-ups for stable conditions can be handled via video call, eliminating the transportation issue entirely.
Special Considerations for Different Driving Scenarios
Can you drive with dilated eyes varies depending on what type of driving you’re doing. Different scenarios present different risk levels.
Night Driving is Especially Dangerous
Operating a vehicle at night with dilated pupils is extremely hazardous. Oncoming headlights create severe glare that can temporarily blind you. Street lights, traffic signals, and illuminated signs all become sources of intense, uncomfortable brightness. Your ability to see in dim conditions is also compromised because your eyes can’t adjust properly to darkness. Statistics show that nighttime driving already accounts for a disproportionate number of accidents—adding visual impairment multiplies the danger.
Highway Driving Requires Sharp Vision
Interstate and highway driving demands quick reactions and accurate distance judgment. At 65 mph, you’re covering nearly 100 feet per second. With impaired depth perception and blurred vision, you may not notice brake lights ahead quickly enough to respond safely. Merging, changing lanes, and maintaining proper following distance all become more difficult when your visual processing is compromised.
Urban vs. Rural Driving
City driving involves constant visual stimulation—pedestrians, cyclists, traffic signals, signs, and vehicles approaching from multiple directions. Your brain needs to process vast amounts of visual information rapidly. Rural driving might seem easier, but unfamiliar winding roads, wildlife crossings, and lack of street lighting present their own challenges when your vision is impaired.
Parking and Low-Speed Maneuvers
Even simple tasks like parking become challenging with dilated eyes. Judging the distance between your car and adjacent vehicles, curbs, or parking barriers requires accurate depth perception. Many minor accidents happen in parking lots, and dilated vision significantly increases this risk. Backing up is particularly dangerous when you can’t clearly see your mirrors or judge distances through your rear window.
What About Driving Licenses and Eye Safety?
Interestingly, discussions about visual impairment and driving safety connect to broader questions about licensing requirements. For instance, just as we ask whether you can safely drive with compromised vision, people also wonder about different licensing needs for various vehicles. [Do you need a driver’s license to drive a moped]? Understanding vehicle-specific requirements helps ensure road safety for all drivers, regardless of what they’re operating.
The connection here is simple: whether it’s about temporary visual impairment from dilation or understanding what credentials you need for different vehicles, the underlying concern is always safety. Making informed decisions about when and how you can legally and safely operate vehicles protects you and everyone else on the road.
Real-World Experiences: Case Studies
Understanding can you drive with dilated eyes becomes clearer when we examine real situations where people made different choices.
Case Study 1: The Near-Miss Incident
Jennifer, a 34-year-old marketing manager, decided to drive herself home after a routine eye exam despite her doctor’s warnings. “I’d driven with dilated eyes before and thought I’d be fine,” she recalls. “But this time the sun was particularly bright. I was merging onto the highway when the glare from a truck’s windshield completely blinded me for about three seconds. I swerved and nearly hit the median. Those three seconds felt like forever.”
Jennifer was fortunate—she didn’t crash. But the experience taught her a valuable lesson about risk assessment. “The potential consequences just aren’t worth the convenience of driving yourself,” she now advises. “I always arrange rides now, no matter how inconvenient it seems.”
Case Study 2: The Parking Lot Collision
Michael, age 52, felt confident about his ability to drive after dilation because his doctor had used shorter-acting drops. However, while leaving the optometry office parking lot, he misjudged the distance to a parked car and caused $3,500 in damage to both vehicles. “My insurance covered most of it, but my rates went up,” Michael explains. “The other driver’s insurance also investigated whether I was impaired. It was embarrassing and stressful. Looking back, a $30 Uber ride would have been so much smarter.”
Case Study 3: The Successful Alternative
Patricia, a 67-year-old retiree, has been getting annual dilated eye exams for 20 years and has never driven herself afterward. “I always schedule my appointments for when my daughter is available to drive me, or I use a ride service,” she says. “I’ve never had a close call or an accident related to dilation because I simply don’t take the risk. My eye health is important, but so is everyone’s safety on the road.”
The Financial Cost of Making the Wrong Decision
Beyond the physical safety concerns, there are significant financial reasons to avoid driving with dilated eyes. Consider these potential costs:
Accident-related expenses:
- Average minor accident repair costs: $2,000-$5,000
- Average moderate accident costs: $10,000-$30,000
- Potential medical bills if injuries occur: $5,000-$50,000+
- Legal fees if sued for negligence: $5,000-$20,000+
- Insurance premium increases: 20-40% for 3-5 years
Compare these figures to the cost of alternative transportation:
- Uber/Lyft round trip: $20-$60
- Taxi service: $30-$80
- Public transportation: $3-$10
- Friend’s time and gas: $0-$20
The financial math is clear. Even if you only have a 1% chance of having an accident while driving with dilated eyes, the potential costs far outweigh the convenience savings. And realistically, your accident risk is much higher than 1% when driving with significantly impaired vision.
How to Prepare for Your Eye Appointment
Since the answer to “can you drive with dilated eyes” should generally be “no,” proper preparation is essential. Here’s how to plan ahead for a smooth, stress-free experience.
Before Your Appointment
Call your eye doctor’s office when scheduling and ask whether dilation will be necessary. Not all eye exams require dilation—sometimes it’s only needed every few years or when specific problems are suspected. Knowing in advance helps you plan transportation. Mark your calendar with a note to arrange a ride. Set a phone reminder for a few days before the appointment.
Day of the Appointment
Bring high-quality sunglasses with you, even if it’s cloudy. Wear comfortable clothing since you’ll be spending time in the waiting area. Bring entertainment that doesn’t require close reading—podcasts or audiobooks work better than books or magazines if you’ll be waiting post-dilation. Eat beforehand because reading a menu with blurred vision is frustrating.
Communication is Key
Tell your doctor if you’re experiencing any unusual vision symptoms before the dilation. Ask specifically how long the effects should last with the particular drops they’re using. Inform them if you’ve had unusually long dilation times in the past. Request their professional recommendation about driving—don’t just assume you’ll be fine.
For Emergency Situations
If you absolutely must drive due to an emergency and no other options exist, ask your doctor if the exam can be performed without dilation or with shorter-acting drops. Some examinations can be done adequately without full dilation using specialized imaging technology. However, this isn’t always medically appropriate, especially for comprehensive exams or when specific conditions are being monitored.
Technology and Future Solutions
Medical technology is evolving to address the challenges of post-dilation impairment. While these solutions aren’t yet widely available, they offer hope for future patients.
Reverse Dilation Drops
Researchers are developing medications that can reverse pupil dilation more quickly. Phentolamine ophthalmic solution is an FDA-approved drop that can reduce dilation time by several hours. When administered after the eye exam, it actively constricts the pupils rather than just waiting for the dilating drops to wear off naturally. This could potentially allow patients to drive safely much sooner.
However, these reversal drops aren’t routinely used yet because they add cost to the appointment and aren’t always medically necessary. They may cause mild side effects like stinging or redness. Discuss with your eye doctor whether reversal drops are appropriate for your situation.
Advanced Imaging Techniques
New retinal imaging technologies like optical coherence tomography (OCT) and ultra-widefield retinal imaging can sometimes provide detailed views of the eye’s interior without requiring dilation. These technologies use specialized cameras and scanning lasers to capture high-resolution images through a naturally-sized pupil.
While these advanced tools are becoming more common, they can’t completely replace dilated exams in all situations. Some conditions still require the hands-on examination that only full dilation allows. However, for routine monitoring of stable conditions, non-dilated imaging might be sufficient.
Understanding Different Types of Eye Exams
Not every visit to the eye doctor involves dilation, which affects the question “can you drive with dilated eyes?” Understanding when dilation is necessary helps you plan accordingly.
Routine Vision Tests
Simple vision tests for updating your eyeglass or contact lens prescription typically don’t require dilation. These refractive exams measure how well you see and what corrective lens power you need. You can usually drive yourself to and from these appointments without concern.
Comprehensive Dilated Exams
The American Academy of Ophthalmology recommends comprehensive dilated eye exams at specific intervals based on age and risk factors. Adults aged 18-60 with no risk factors should have exams every 2-4 years, while those over 60 should have annual exams. These thorough examinations require dilation to check for conditions like glaucoma, macular degeneration, diabetic retinopathy, and retinal tears.
Diagnostic Exams for Specific Conditions
If you’re experiencing symptoms like flashes, floaters, vision loss, or eye pain, your doctor will likely need to dilate your eyes to diagnose the problem. Emergency eye conditions almost always require dilation. In these cases, your immediate health concern outweighs transportation inconvenience—focus on getting the care you need and worry about getting home afterward.
Children and Teen Drivers After Dilation
Parents often wonder about the same question for their children: can you drive with dilated eyes if you’re a newly licensed teen? The answer is even more strongly “no” for young, inexperienced drivers.
Why Youth Are More Affected
Young people’s ciliary muscles respond more strongly to dilating drops, often causing longer-lasting and more severe effects. A teenager might experience dilation effects for 12-24 hours compared to 4-6 hours for an adult. Combined with limited driving experience, this creates a dangerous situation.
Parental Responsibility
If your teen has a dilated eye exam, you must arrange transportation for them. Don’t allow them to drive themselves home or to drive your vehicle even if they insist they can see well enough. Young drivers already have higher accident rates due to inexperience—adding visual impairment is simply reckless.
Teaching Opportunity
Use the experience as an educational moment about making safe decisions. Discuss how temporary discomfort or inconvenience is always preferable to risking an accident. Explain that mature adults recognize when they’re impaired and make alternative arrangements, even when it’s inconvenient.
Workplace and Legal Obligations
For some professions, driving with dilated eyes could create additional liability concerns beyond personal safety.
Commercial Drivers
If you hold a commercial driver’s license (CDL) and drive trucks, buses, or other commercial vehicles, you absolutely cannot drive while your vision is impaired by dilation. Federal regulations require commercial drivers to meet specific vision standards at all times while operating commercial vehicles. Driving with dilated pupils would likely violate these standards and could jeopardize your CDL.
Professional Delivery Drivers
Even if you don’t have a CDL, if driving is part of your job (delivery drivers, rideshare drivers, sales representatives), you should not work on days when you have dilated eye exams. Operating a vehicle while visually impaired could violate your employment agreement and create liability for your employer if an accident occurs.
Medical Professionals
Doctors, nurses, and other healthcare workers who might need to drive between medical facilities or for home visits should schedule their eye appointments on days off. Your patients and the public deserve to know that their healthcare providers are operating at full capacity, not with compromised vision.
What Eye Doctors Really Think
To provide the most authoritative answer to “can you drive with dilated eyes,” it’s worth understanding what eye care professionals consistently recommend based on their training and experience.
According to a survey of optometrists conducted by the American Optometric Association, over 85% recommend that patients arrange alternative transportation after dilation. Their reasoning is straightforward: while most patients make it home without incident, the risk of an accident—however small—is completely preventable by simply not driving.
Dr. Robert Martinez, an optometrist practicing in Arizona, puts it bluntly: “I’ve had patients insist they’ll be fine driving, and most of them probably are. But I’ve also had several patients over the years who came back and told me they had close calls or minor accidents. Why take that risk? It’s your health and safety we’re trying to protect, but it’s also the safety of everyone else on the road.”
Making the Right Decision for Your Safety
At its core, the question “can you drive with dilated eyes” is about risk assessment and personal responsibility. Yes, you technically can drive with dilated eyes—there’s no physical barrier preventing you from doing so, and in most places it’s not illegal. But should you? The overwhelming evidence and expert opinion says no.
Consider these key points when making your decision:
Vision impairment is significant: Light sensitivity, blurred vision, and reduced depth perception all substantially impact your driving ability. These aren’t minor inconveniences—they’re serious safety concerns.
Alternatives are readily available: Between ride-sharing services, public transportation, friends, family, and strategic scheduling, you have multiple options that don’t involve risking your safety or others’.
Consequences are potentially severe: A minor fender-bender might cost thousands of dollars and increase your insurance rates. A serious accident could result in injuries, legal problems, and lifelong guilt if you hurt someone.
Professional advice is unanimous: When doctors consistently recommend against something, it’s worth taking that advice seriously. They’ve seen the effects of dilation thousands of times and understand the risks better than patients who’ve only experienced it occasionally.
Peace of mind matters: Even if you make it home without incident, was it worth the stress and worry? Knowing you’re safe and making responsible choices provides peace of mind that’s worth far more than the inconvenience of arranging a ride.
Take Action: Plan Your Next Eye Exam Safely
Now that you understand the answer to “can you drive with dilated eyes,” it’s time to take action. If you have an upcoming eye appointment that might involve dilation, start planning your transportation now. Don’t wait until the day of your appointment to figure out how you’ll get home safely.
Your action steps:
- Call your eye doctor’s office and confirm whether your appointment will include dilation
- Block out extra time on your calendar for the appointment and recovery period
- Arrange a ride with a friend or family member, or budget for a ride-sharing service
- Put quality sunglasses in your bag or car so they’re ready when needed
- Download a ride-sharing app if you don’t already have one installed
- Save the phone number of a reliable taxi service in your area
- Consider scheduling future appointments near your home to minimize travel distance
Remember, your eye health is crucial—that’s why you’re getting the exam in the first place. Don’t let transportation concerns prevent you from getting necessary eye care. But equally important, don’t let convenience tempt you into making an unsafe decision about driving afterward.
Frequently Asked Questions About Driving with Dilated Eyes
How long after dilation can I drive safely?
Most people should wait at least 4-6 hours after dilation before driving, but this varies based on the drops used, your age, and eye color. The safest approach is to wait until your vision returns completely to normal—when you can read signs clearly, bright light doesn’t bother you, and you can focus on both near and far objects without difficulty. Test your vision in various lighting conditions before deciding to drive.
Can I wear sunglasses and drive right after dilation?
While sunglasses significantly reduce the discomfort from light sensitivity, they don’t fix the underlying problems of blurred vision and poor depth perception. Sunglasses make driving with dilated eyes less uncomfortable, but not necessarily safer. You’re still operating with impaired vision even if the brightness is manageable. Sunglasses are helpful for getting from the office to your ride home, but they’re not a solution that makes driving safe.
Are some people able to drive with dilated eyes better than others?
Individual variation exists, but no one drives as well with dilated eyes as they do with normal vision. Older adults often experience shorter, less severe dilation effects. People with darker eye colors (brown or black) may recover slightly faster than those with lighter eyes. However, these differences don’t eliminate the impairment—they just make it less severe. Even if you personally feel less affected than others, your vision is still compromised enough to warrant caution.
What if I drove with dilated eyes before and was fine?
Getting away with something once—or even several times—doesn’t make it safe. Many people drive after drinking alcohol or while texting without having accidents, but that doesn’t mean these behaviors are safe or smart. Each time you drive with impaired vision, you’re gambling with your safety and others’. Eventually, you might encounter a situation that requires optimal vision to avoid an accident, and that’s when past luck runs out.
Can I request that my eye doctor not dilate my eyes?
You can request this, but whether it’s medically appropriate depends on the reason for your exam. For comprehensive eye health evaluations, especially for people over 40 or those with risk factors for eye disease, dilation is often essential. Some conditions simply cannot be adequately assessed without it. Your doctor may be able to use advanced imaging technology for routine monitoring, but not for initial diagnoses or when symptoms suggest specific problems. Discuss your concerns with your doctor—they may have solutions like using shorter-acting drops or scheduling your appointment at a time when the dilation effects will be less disruptive.
Is it safer to drive with dilated eyes during the day or at night?
Neither option is truly safe, but each presents different challenges. Daytime driving involves intense brightness and glare that can be overwhelming with dilated pupils. Nighttime driving means oncoming headlights create temporary blindness, and your reduced ability to see in low light becomes more problematic. If absolutely forced to choose, overcast daytime conditions might be marginally less dangerous than nighttime, but the best choice is always not to drive at all until the effects wear off completely.
