Human eyes don’t see well in the dark. Without light, our depth perception, color recognition, ability to see contrast, and peripheral vision can be compromised. All of which makes driving at night more dangerous than day driving. Keeping these do’s and don’ts in mind can help you stay safer behind the wheel after dark.

Don’t follow too closely.

At night, your field of vision is limited to the area illuminated by your headlights. Even with your high-beam headlights on, that may only be about 500 feet (and only about 250 feet with low beams). To give yourself plenty of stopping time, slow down and increase the typical distance between you and the car you’re following.

Don’t look directly into oncoming headlights.

The glare from an approaching car can temporarily blind you—especially if the driver fails to turn down their high beams—and it could take several seconds for your eyes to readjust to the darkness. Look down toward the right side of the road and follow the lane marking to stay on course until the vehicle passes.

Do dim your dashboard lights.

The glow from your car’s instrument panel and infotainment system can be distracting. The lights can also cause reflections on the windshield that make it tougher for your eyes to adjust to the darkness outside the car. Using the dimmer switch to tone these down can help.

Do wear the right glasses.

After driving on a sunny day, it takes time for your eyes to adjust to the low light when darkness falls. Wear a good pair of sunglasses when driving on bright days and take them off as soon as the sun goes down. If you wear prescription glasses, choose a pair with anti-reflective lenses to cut down on the amount of light reflecting inside your specs.

Don’t ignore a streaky windshield.

Driving at night can reveal streaks in your windshield that weren’t visible in the daylight. Be sure it’s clean by wiping the inside of the glass with a microfiber cloth and glass cleaner. And never touch the inside of the glass with your bare hands; the oil from your skin can leave smears and smudges.

Do make sure your headlights are in good shape.

Even in new cars, headlights can sometimes be uneven or pointed too low. You can adjust them yourself using instructions in your owner’s manual or take your car to your local AAA Approved Auto Repair facility for help. If you have an older car with plastic lens covers that have yellowed, use a polish kit to clear off the residue (AAA Members save 10% and earn reward points on most auto parts and accessories at NAPA).

Driving at night: Tips for older drivers

As you get older, your field of vision shrinks. Your eyes at age 60 need three times as much light to see as they did at age 20, because over time pupils get smaller and don’t dilate as well. That can make driving at night even tougher.

To compensate, an older driver should scan farther down the road and be certain to move their head, not just their eyes, to make up for reduced peripheral vision.

The American Optometric Association also offers this advice to senior drivers:

  • Have annual eye exams to check for potential problems such as cataracts and degenerative eye diseases, and to make sure your prescription for any corrective eyewear is current.
  • Take a driving course for seniors, which can help you learn to adjust for the physical changes that come with aging.
  • Avoid glasses or sunglasses with wide temples (the arms on the sides that extend over the ears), as these can impede your side vision.
  • Reduce your speed or even avoid driving at night, if necessary.
