Older drivers have even greater difficulties seeing at night. Another factor adding danger to night driving is fatigue. Drowsiness makes driving more difficult by dulling concentration and slowing reaction time. Alcohol is a leading factor in fatal traffic crashes, playing a part in about half of all motor vehicle-related deaths. That makes weekend nights more dangerous.
More fatal crashes take place on weekend nights than at any other time in the week.
Fortunately, you can take several effective measures to minimize these after-dark dangers by preparing your car and following special guidelines while you drive. Have your headlights properly aimed. Misaimed headlights blind other drivers and reduce your ability to see the road. Don't drink and drive. Not only does alcohol severely impair your driving ability, but it also acts as a depressant.
