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’re driving on snow or ice, it’s easy
to ask more of those control systems than the tires and
road can provide. That means you can lose control of your
vehicle. Also see “Traction Control System” in the Index.
Braking
Braking action involves perception time and
reaction time.
First, you have to decide to push on the brake pedal.
That’s perception time. Then you have to bring up
your foot and do it. That’s reaction time.
Average reaction time is about 3/4 of a second.
But that’s 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 3/4 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’s pavement or gravel);
the condition of the road (wet, dry, icy); tire tread; the
condition of your brakes; the weight of the vehicle and
the amount of brake force applied.
