steering, acceleration, or  braking 
(including  engine  bralting  by shifting  to 
a  lower  gear).  Any sudden  changes 
could  cause the tires  to slide.  You  may 
not  realize  the surface  is slippery  until 
your  vehicle  is  skidding. Learn to 
recognize  warning  clues 
- such  as 
enough water,  ice or packed  snow on 
the  road  to make  a “mirrored surface” 
- and slow  down  when you  have  any 
doubt. 
Remember:  Any  anti-lock  braking  system  (ABS)  helps  avoid  only  the 
braking  skid. 
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. 
Don’t drink and  drive. 
Adjust your  inside  rearview  mirror  to 
reduce  the glare  from  headlights 
behind  you. 
Since  you can’t  see  as well,  you  may 
need  to slow  down  and keep  more 
space  between  you and other  vehicles.

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  glare  from  headlights,  but they  also 
make  a lot  of things  invisible. 
You 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  (as from
