Driving at Night
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.
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.
D Slow down, especially on higher speed roads. Your
headlamps can light up only so much road ahead.
D In remote areas, watch for animals.
D If you’re tired, pull off the road in a safe place
and rest.
