If other cars are lined up to pass a slow vehicle, wait your turn. But
take care that someone isn’t trying to pass you as you pull out to pass
the slow vehicle. Remember to glance over your shoulder and check
the blind spot.
Check your mirrors
, glance over your shoulder, and start your left
lane change signal before moving out
of the right lane to pass. When
you are far enough ahead
of the passed vehicle to see its front in your
inside mirror, activate your right lane change signal and move back
into the right lane. (Remember that your right outside mirror is
convex. The vehicle
you just passed may seem to be farther away from
you than it really is.)
Try not to pass more than one vehicle at a time on two-lane roads.
Reconsider before passing the
next vehicle.
Don’t overtake
a slowly moving vehicle too rapidly. Even though the
brake lights are not flashing, it may be slowing down or starting to
turn.
If you’re being passed, make it easy for the following driver to get
ahead of you. Perhaps you can ease a little to the right.
LOSS OF CONTROL
Let’s review what driving experts say about what happens when the three
control systems (brakes, steering and acceleration) don’t have enough
friction where the tires meet the road to do what
the driver has asked.
In any emergency, don’t give up. Keep trying to steer and constantly seek
an escape route or area
of less danger.
Skidding
In a skid, a driver can lose control of the vehicle. Defensive drivers avoid
most skids by taking reasonable care suited to existing conditions, and
by
not “overdriving” those conditions. But skids are always possible.
The three types
of skids correspond to your Cadillac’s three control
systems. In the braking skid your wheels aren’t rolling. In the steering or
cornering skid, too much speed
or steering in a curve causes tires to slip
and
lose cornering force. And in the acceleration skid too much throttle
causes the driving wheels to spin.

Downloaded from www.Manualslib.com manuals search engine Just as your headlights should be checked regularly for proper aim, so
should your eyes be examined regularly. Some drivers suffer from night
blindness
-- the inability to see in dim light -- and aren’t even aware of it.
DRn/lNG IN THE RAIN
Rain and wet roads can mean driving trouble. On a wet road you can’t
stop, accelerate or turn as well because your tire-to-road traction isn’t as
good
as on dry roads. And, if your tires don’t have much tread left, you’ll
get even less traction.
It’s always wise to go slower and be cautious if rain starts to fall while you
are driving. The surface may get wet suddenly when your reflexes are
tuned for driving on dry pavement.
The heavier the rain, the harder it is to see. Even if your windshield wiper
blades are
in good shape, a heavy rain can makc it harder to see road
signs and traffic signals, pavement markings, the edge
of the road, and
even people walking. Road spray can often be worse for vision than rain,
especially
if it comes from a dirty road.
So it is wise to keep your wiping equipment in good shape and keep your
windshield washer tank filled. Replace your windshield wiper inserts
when they show signs of streaking or missing areas on the windshield,
or
when strips of rubber start to separate from the inserts.
