Control of a Vehicle

You have three systems that make your vehicle go

where you want it to go. They are the brakes, the

steering, and the accelerator. All three systems

have to do their work at the places where the tires

meet the road.

Sometimes, as when you are driving on snow or

ice, it is easy to ask more of those control systems

than the tires and road can provide. That means

you can lose control of your vehicle. See Traction

Control System (TCS) on page 291.

Adding non-GM accessories can affect your

vehicle’s performance. See Accessories and

Modiﬁcations on page 333.

Braking

See Brake System Warning Light on page 178.

Braking action involves perception time and

reaction time.

First, you have to decide to push on the brake

pedal. That is perception time. Then you have to

bring up your foot and do it. That is reaction time.

Average reaction time is about three-fourths of a

second. But that is only an average. It might

be less with one driver and as long as two or

three seconds or more with another. Age, physical

condition, alertness, coordination, and eyesight

all play a part. So do alcohol, drugs, and

frustration. But even in three-fourths of a second,

a vehicle moving at 60 mph (100 km/h) travels

66 feet (20 m). That could be a lot of distance in

an emergency, so keeping enough space between

your vehicle and others is important.

And, of course, actual stopping distances vary

greatly with the surface of the road, whether it is

pavement or gravel; the condition of the road,

whether it is wet, dry, or icy; tire tread; the

condition of the brakes; the weight of the vehicle;

and the amount of brake force applied.
