Here are sometips on night driving. Drive defensively. Don't drink and drive. * 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. 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. Night Vision 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 headlights, butthey also make a lot of things invisible. You can be temporarily blinded by approaching lights. It can take a second or two, or even several seconds, foryour eyes to readjust to the dark. When you are faced with severe glare(as from a driver whodoesn't lower the high beams, or avehicle with misaimed headlights), slow down a little. Avoid staring directly into the approaching lights. Keep your windshield and all the glass on your vehicle clean - inside and out. Glare at night is made much worse by dirt on the glass. Even the inside of the glass can build up a film caused by dust. Dirty glass makes lights dazzle and flash more than clean glass would, making the pupils of your eyes contractrepeatedly. Remember that your headlights light up far less of a roadway when you are in a turn or curve. Keep your eyes moving; that way, it's easier to pick out dimly lighted objects. Just as your headlights should be checked regularly for proper aim, so should your eyes be examined regularly. Some drivers suffer from nightblindness the inability to see in dim light - and aren't even aware of it. - 4-24
