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. 
0 Don’t  drink  and  drive. 
0 Adjust  your  inside rearview  mirror to  reduce the 
glare  from  headlamps  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 
headlamps  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. 
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  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  doesn’t  lower the high  beams,  or  a  vehicle with 
misaimed headlamps), slow down  a little. Avoid staring 
directly into the approaching headlamps.
