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.
•
Drive defensively.
•
Do not drink and drive.
•
Adjust the inside rearview mirror to reduce the
glare from headlamps behind you.
•
Since you cannot see as well, slow down and
keep more space between you and other
vehicles.
•
Slow down, especially on higher speed roads.
Your vehicle’s headlamps can light up only so
much road ahead.
•
In remote areas, watch for animals.
•
If you are tired, pull off the road in a safe
place and 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 might 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 are driving, do not
wear sunglasses at night. They might cut down on
glare from headlamps, but they also make a lot
of things invisible.
You can be temporarily blinded by approaching
headlamps. It can take a second or two, or
even several seconds, for your eyes to re-adjust
to the dark. When you are faced with severe glare,
as from a driver who does not lower the high
beams, or a vehicle with misaimed headlamps,
slow down a little. Avoid staring directly into
the approaching headlamps.
