Your Driving andthe Road Night Vision Driving at Night Night driving is more dangerous than day driving. One reason is that some drivers are likely to be impaired-by alcohol or drugs, with night vision problems, or by fatigue. Here are some tips on night driving. Drive defensively. Remember, this is the most dangerous time. Don't drink and drive. (See the Index under Drunken Driving for more on this problem.) Adjust your inside rearview mirror to reduce the glare from headlights behind you. Since you can't see as well, you may need to slow down and keep more space between you and other vehicles. It's hard to tell how fast the vehicle ahead is goingjust by looking at its taillights. Slow down, especially on higher speed roads. Your headlights can light up only so much road ahead. In remote areas, watch for animals. If you're tired, pull off the road in a safe place and rest. No one can seeas well at night as in the daytime. But as we get older these differences increase. A 50-year-old driver may require at least twice as much light to see the same thing at night as a 20-year-old. What you do in the daytime can also affect your night vision. For example, if you spend the day in bright sunshine you are wise to wear sunglasses. Your eyes will have less trouble adjusting to night. But if you're driving, don't wear sunglasses at night. Theymay cut down on glare from headlights, but they also make a lot of things invisible that should remain visible-such as parked cars, obstacles, pedestrians,or even trains blocking railway crossings. Youmay want to put on your sunglasses after you have pulled into a brightly-lighted service or refreshment area. Eyes 1 2 4
