Steering Tips

Driving on Curves

It’s important to take curves at a reasonable speed.

A lot of the “driver lost control” accidents mentioned on
the news happen on curves. Here’s 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’s no traction, inertia will keep
the vehicle going in the same direction. If you’ve ever
tried to steer a vehicle on wet ice, you’ll understand this.

The traction you can get in a curve depends on the
condition of your tires and the road surface, the angle 
at which the curve is banked, and your speed. 
While you’re in a curve, speed is the one factor you 
can control.

Suppose you’re steering through a sharp curve. Then
you suddenly accelerate. Both control systems

 have to do their work where

the tires meet the road. Adding the sudden acceleration
can demand too much of those places. You can lose
control. Refer to “Traction Control” in the Index.

What should you do if this ever happens? Ease up on the
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’ll want to go slower.

If you need to reduce your speed as you approach a
curve, do it before you enter the curve, while your front
wheels are straight ahead.

Try to adjust your speed so you can “drive” through the
curve. Maintain a reasonable, steady speed. Wait to
accelerate until you are out of the curve, and then
accelerate gently into the straightaway.
