Steering

Power Steering

If you lose power steering assist because the engine

stops or the system is not functioning, you can steer

but it will take much more effort.

Steering Tips

It is important to take curves at a reasonable speed.

A lot of the “driver lost control” accidents mentioned on

the news happen on curves. Here is why:

Experienced driver or beginner, each of us is subject to

the same laws of physics when driving on curves.

The traction of the tires against the road surface makes

it possible for the vehicle to change its path when

you turn the front wheels. If there is no traction, inertia

will keep the vehicle going in the same direction.

If you have ever tried to steer a vehicle on wet ice,

you will understand this.

The traction you can get in a curve depends on the

condition of the tires and the road surface, the angle at

which the curve is banked, and your speed. While you

are in a curve, speed is the one factor you can control.

Suppose you are steering through a sharp curve.

Then you suddenly apply the brakes. Both control

systems — steering and braking — have to do their work

where the tires meet the road. Unless you have

antilock brakes, adding the hard braking can demand

too much of those places. You can lose control.

The same thing can happen if you are steering through

a sharp curve and you suddenly accelerate. Those

two control systems — steering and acceleration — can

overwhelm those places where the tires meet the road

and make you lose control.

What should you do if this ever happens? Ease up on

the brake or accelerator pedal, steer the vehicle the way

you want it to go, and slow down.

Speed limit signs near curves warn that you should

adjust your speed. Of course, the posted speeds

are based on good weather and road conditions.

Under less favorable conditions you will want to

go slower.

If you need to reduce your speed as you approach a

curve, do it before you enter the curve, while the

front wheels are straight ahead.
