1993 Cadillac DeVille Owner's Manual - Page 207

Adjust your inside rearview mirror to reduce the glare from headlights behind you. Since you can't see aswell, you may need to slow down and keep more space between you and othervehicles. It'shard to tell how fast the vehicle ahead is going just by looking at its taillights. Slow down, especially on higher speed roads.Your headlights can light up only so much road ahead. 0 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 glarefrom 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. You may want to put on your sunglasses after you havepulled into a brightly-lighted service or refreshment area. Eyes shielded from that glaremay adjust more quickly to darkness back on the road.But be sure to remove your sunglasses before you leave the service area. IOU can be temporarily blinded by approaching lights. It can take a second or two, or even several seconds, for your eyes to readjust to the dark. When you are faced with severe glare (asfrom a driver who doesn't lower the high beams, or a vehicle withmisaimed headlights), slow down a little. Avoid staring directly into theapproaching lights. If there is a line of opposing traffic, make occasional glances over the line of headlights to make certain thatone of the vehicles isn't starting tomove into your lane. Once you are past the bright lights, giveyour eyes time to readjustbefore resuming speed. 194
