When oncoming headlights wash out your view, do not stare at the lamps or jerk the steering wheel. Keep your vehicle in its lane, shift your eyes toward the right edge or fog line, slow to a speed that matches what you can actually see, and be ready to pull completely off the road if visibility is not adequate. Never stop in a travel lane, and do not answer another driver’s glare with your high beams.
Those steps address the immediate danger. Clean glass, correctly aimed lights, suitable low-beam use in poor weather, and an up-to-date vision prescription can reduce recurring problems. Severe or persistent light sensitivity deserves an eye-care evaluation rather than a gadget marketed as a cure.
What to do the moment headlights become blinding
Glare can temporarily erase lane markings, pedestrians, stopped vehicles, curves and other hazards. Treat the loss of visual information as a reason to reduce risk, not as a challenge to keep your previous speed.
- Stop looking at the lamps. Keep your attention on the roadway. Oregon driver guidance says to look a little to the right of oncoming lights and watch the road edge or fog line. Use that edge as a reference while continuing to scan for hazards.
- Hold your lane. Keep both hands available for steering, make only small corrections and avoid drifting toward the center line. Do not make an abrupt move into the shoulder or opposing lane simply because the light is uncomfortable.
- Slow down smoothly. Ease off the accelerator and choose a speed at which you can stop within the distance you can see. Watch for stopped vehicles, people, animals, debris, driveways and changes in the road edge.
- Let the vehicle pass. Keep the right side of your lane as appropriate for the road, without riding the shoulder or crossing a line. Once the lights are past and your view returns, reassess your speed before accelerating.
- Pull off if you still cannot see safely. Signal, move to a genuinely safe location outside the travel lane and stop. A legal, stable pull-off is safer than continuing with a view you cannot trust. Never stop in a live traffic lane.

Oregon Department of Transportation Driver and Motor Vehicle Services, Oregon Driver Manual
This is a visual-reference technique, not permission to stop watching the rest of the road. Keep scanning ahead and use the right edge only as an orientation aid while the glare lasts.
Where should you look when a vehicle approaches?
Use the right road edge or fog line
The right edge gives your eyes a fixed, lower-contrast reference that is away from the brightest part of the oncoming beam. Depending on the road, that reference may be a painted fog line, pavement edge, curb, shoulder boundary or a consistent row of roadside markers. Look near—not far beyond—the edge so you can maintain lane position without fixating on one point.

Glare does not make hazards disappear; it makes them harder to detect. Sweep your attention between the edge reference, the lane ahead and likely conflict areas such as intersections, parked cars, crosswalks and bends. If the road curves, use the visible roadway and edge line to follow the curve rather than steering toward the lights.
Do not close your eyes or look in the mirror
Closing your eyes, turning your head away or checking a mirror removes even more information from the driving scene. A brief glance toward the right is different from abandoning the forward view. Keep your head oriented toward the road and your gaze moving.

How much should you slow down?
There is no single safe speed because glare depends on the road, weather, traffic, lighting and how much distance remains visible. Use a visibility-based rule: if you cannot identify a stopped object far enough ahead to stop, your speed is too high for the conditions.
- Reduce speed before a crest, curve, intersection or narrow section where an unseen hazard could appear.
- Increase following distance so another vehicle’s lights do not force an immediate maneuver.
- Expect a second visual adjustment after the vehicle passes. Your eyes may need a moment to recover, so do not accelerate the instant the lamps leave your view.
- If several vehicles approach in succession, maintain the reduced speed until you have a sustained clear view.
Hazard lights, emergency flashers or other signals do not make it safe to stop in a traffic lane. If stopping is necessary, continue only far enough to reach a safe place outside moving traffic.

Do not retaliate with high beams
Oregon’s parent and teen driving guidance specifically says not to look into oncoming headlights or flash high-beam lights at others. Turning on your high beams to “get back at” a driver can add glare for both vehicles, provoke another response and make the road harder to read. Keep the lighting setting that is appropriate for the traffic and conditions, and concentrate on lane control.
Do not swerve toward the shoulder or center line
A sudden steering movement can put your vehicle into a ditch, curb, roadside object or opposing traffic. Make gradual corrections using the lane markings and edge as references. If you cannot maintain the lane without a large steering movement, slow further and find a safe place to stop.
Do not use sunglasses or tinted lenses at night
Dark or tinted lenses reduce the light reaching your eyes. NHTSA guidance advises against sunglasses or tinted lenses at night. They are not a substitute for correcting a prescription, cleaning the vehicle or stopping when visibility is inadequate.

Low beams, high beams and poor weather
Headlight glare is not limited to a driver’s beam choice. In fog, dust, smoke or similar low-visibility conditions, high beams can reflect back toward you and make the scene harder to see. Use low beams in those conditions and follow the beam-use requirements in your jurisdiction.
Do these 3 things before closing this tab:
1Clear out junk files and repair common Windows errors2Scan for outdated or missing drivers - takes under a minute3Repair Windows errors before they cause bigger problemsWhen approaching traffic, use the setting required by local law and dim as required. Beam-distance rules differ by jurisdiction, so do not treat a specific state’s distances as a nationwide rule. The safety principle is consistent: never use a beam setting that creates avoidable glare for another road user.
When a vehicle behind you is bright
Rear-view glare can also reduce your view. Keep your attention on the road ahead, use the mirror’s night setting if your vehicle has one, and allow the following vehicle to pass when it is safe. Avoid staring at the mirror or making a sudden maneuver to escape the light.
Prepare the vehicle before the next night drive
Clean the windshield inside and out
A film on the glass scatters light and can turn each headlamp into a broad haze. Clean the outside and inside of the windshield with a suitable glass cleaner and a clean microfiber cloth. Remove residue from the area in front of the driver’s field of view, and replace worn wipers that leave streaks. Cleaning improves the view; it does not make it safe to drive when you cannot see adequately.
Clean mirrors and headlamp lenses
Dirty side mirrors and a hazy headlamp lens reduce useful contrast. Wipe mirrors and exterior lamps as part of routine vehicle care, especially after road spray, dust or snow. Check that no cargo, accessory or damage blocks a lamp.

Have headlight aim checked
Misaligned headlights can point too high and create glare for approaching drivers while providing an uneven view for you. Ask for headlight aim to be checked during vehicle inspection or service. An aim check is different from simply replacing a bulb; both the direction and the condition of the lighting system matter.
Check the rest of the driver’s view
- Keep the dashboard and windshield area free of objects that block the lower or side view.
- Make sure mirrors are adjusted before moving.
- Remove ice, snow or condensation that obscures any portion of the glass.
- Replace a damaged windshield when cracks, chips or distortion interfere with seeing the lane.
Should you wear “night-driving” glasses?
Yellow, amber or other tinted “night-driving” glasses are often marketed as a glare solution, but the cited NHTSA guidance says not to wear sunglasses or tinted lenses at night. A tint can reduce the light available to your eyes and does not correct an incorrectly prescribed lens, a dirty windshield or a headlight-aim problem.
If you wear prescription glasses, use a current prescription and keep the lenses clean. Ask your optometrist or ophthalmologist whether an anti-reflective treatment or another correction is appropriate for your eyes; do not assume that a non-prescription tint treats the cause of glare.
Independent reader supportYour contribution helps us test, update, and keep practical guides available for everyone.When recurring glare warrants an eye appointment
Arrange an eye-care evaluation if headlights remain unusually difficult to tolerate after you have addressed vehicle cleanliness and lighting, or if the problem is new, worsening or present with ordinary indoor lights. NHTSA advises people who are extremely light-sensitive to ask an eye doctor whether the problem can be corrected. That advice is directed to older drivers, but severe light sensitivity can have many causes and should not be attributed to age alone.
Seek prompt medical advice for glare accompanied by eye pain, a sudden change in vision, flashes, a curtain-like shadow, marked redness or a severe headache. Do not drive yourself if your vision is suddenly impaired. An eye-care professional can determine whether a prescription change or another evaluation is needed; this article cannot diagnose an eye condition.

What to do in common situations
You are on a two-lane rural road
Move your gaze to the right edge or fog line, keep the vehicle in its lane and reduce speed before the approaching vehicle reaches you. Watch for an unmarked shoulder, a parked vehicle or a pedestrian at the edge. If the opposing traffic continues and you cannot identify the lane safely, use a safe pull-off rather than stopping on the roadway.
You are entering a curve or hill
Slow before the curve or crest, not after the glare has already erased the view. Keep a steady lane position and do not follow the apparent direction of the light. Be prepared for a vehicle, bicyclist or obstruction that was hidden behind the curve.
You are in fog, dust or smoke
Use low beams, increase following distance and reduce speed further. High beams can reflect from suspended particles and worsen the backscatter. If the air is so thick that lane edges and hazards cannot be identified, leave the travel lane at a safe location and wait for visibility to improve.
Recommended Free Tools
You are on a multilane road
Hold your lane and avoid an abrupt lane change while glare is present. Check mirrors and blind spots only when you can do so without losing forward control. If you need to slow substantially, do so smoothly and leave extra space for vehicles behind.
You are already too dazzled to continue
Signal, reduce speed and move completely off the travel lane when a safe shoulder, parking area or other legal stopping place is available. Keep the vehicle stopped until you can see well enough to re-enter. Do not rely on hazard lights as a substitute for getting out of moving traffic.
A simple pre-drive and in-the-moment checklist
Before driving at night
- Clean the inside and outside of the windshield, mirrors and headlamp lenses.
- Confirm that your prescription glasses are current and clean; leave tinted lenses out of nighttime driving.
- Check that headlights are working and ask for aim inspection if the beam looks uneven or unusually high.
- Plan a slower pace and more following distance for fog, smoke, dust, rain or unfamiliar roads.
During an oncoming-glare event
- Look slightly right toward the road edge or fog line.
- Keep the vehicle centered safely in its lane with small steering inputs.
- Ease off the accelerator and scan for hazards.
- Do not flash high beams or stare at the other vehicle.
- Pull off safely if you cannot see enough to proceed.
The practical bottom line
Oncoming headlights are a visibility problem, so respond by protecting the information you still have: use the right road edge as a reference, preserve your lane, slow down and stop outside the travel lane when necessary. Keep glass and lights clean, have headlight aim checked, use low beams in conditions where high beams reflect back, and avoid tinted lenses at night. If glare remains severe or keeps getting worse, make an eye-care appointment before treating it as a normal part of driving.
