Hydroplaning 
Hydroplaning is dangerous.  So  much water can build  up 
under  your tires that they  can actually ride  on the 
water. This  can  happen 
if the  road is wet  enough  and 
you’re  going fast  enough.  When  your vehicle is 
hydroplaning, it  has little  or  no  contact with the  road. 
Hydroplaning doesn’t  happen often. But it can 
if 
your  tires  do  not  have  much  tread or if the  pressure in 
one  or more  is low.  It can  happen 
if a lot of water is 
standing  on  the road. If  you  can  see  reflections 
from trees, telephone poles  or other vehicles,  and 
raindrops “dimple”  the water’s surface, there could  be 
hydroplaning. 
Hydroplaning usually  happens  at higher speeds.  There 
just  isn’t  a hard  and fast  rule about hydroplaning. 
The  best  advice is to  slow  down  when  it is raining. 
Driving Through  Deep Standing  Water 
Notice: If  you  drive  too  quickly  through  deep 
puddles  or  standing  water,  water  can  come  in 
through  your  engine’s  air  intake  and  badly  damage  your  engine.  Never drive  through  water  that  is 
slightly  lower  than  the  underbody 
of your  vehicle. If 
you  can’t  avoid  deep puddles  or  standing  water, 
drive  through  them  very  slowly. 
Driving Through Flowhg W=+er 
--m 
Flowing  or  rushing  water  creates  strong  forces. 
If  you  try  to  drive  through  flowing  water, as you 
might  at a  low  water  crossing,  your  vehicle  can 
be  carried  away. 
As little as six  inches  of 
flowing  water  can  carry  away 
a smaller  vehicle. 
If this  happens,  you  and  other  vehicle 
occupants  could  drown.  Don’t  ignore  police 
warning  signs,  and  otherwise  be very  cautious 
about  trying  to  drive  through  flowing  water. 
Some Other  Rainy  Weather  Tips 
Turn  on  your  low-beam  headlamps - not just  your 
parking  lamps 
- to help  make  you  more  visible  to 
others. 
Besides slowing  down,  allow  some  extra  following 
distance.  And be especially  careful when you 
pass  another  vehicle.  Allow  yourself  more  clear 
room  ahead, and  be prepared to  have  your 
view  restricted  by road spray. 
Have  good  tires with  proper  tread depth.  See 
Tires 
on page 5-6 I.
