Driving at Night Here are some tips on night driving. D Drive defensively. D Don't drink and drive. D Since you can't see as well, you may need to slow down and keep more space between you and other vehicles. Your headlamps can light up only so much road ahead. D Slow down, especially on higher speed roads. D In remote areas, watch for animals. D If you're tired, pull off the road in a safe place and rest. No one can see as 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. They may cut down on glare from headlamps, but they also make a lot of things invisible. 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. 4-16
