Driving at NightNight driving is more dangerous than day driving. Onereason is that some drivers are likely to be impaired — byalcohol or drugs, with night vision problems, or by fatigue.Here are some tips on night driving.• Drive defensively.• Do not drink and drive.• Since you can not see as well, you may need toslow down and keep more space between youand other vehicles.• Slow down, especially on higher speed roads.Your headlamps can light up only so muchroad ahead.• In remote areas, watch for animals.• If you are tired, pull off the road in a safe placeand 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 muchlight to see the same thing at night as a 20-year-old.What you do in the daytime can also affect yournight vision. For example, if you spend the day in brightsunshine you are wise to wear sunglasses. Your eyeswill have less trouble adjusting to night. But if youare driving, do not wear sunglasses at night. They maycut down on glare from headlamps, but they alsomake a lot of things invisible.4-17
