For persons under 21, it is against the law in every

U.S. state to drink alcohol. There are good medical,

psychological, and developmental reasons for

these laws.

The obvious way to eliminate the leading highway

safety problem is for people never to drink alcohol and

then drive.

Medical research shows that alcohol in a person’s

system can make crash injuries worse, especially

injuries to the brain, spinal cord, or heart. This means

that when anyone who has been drinking — driver

or passenger — is in a crash, that person’s chance of

being killed or permanently disabled is higher than if the

person had not been drinking.

Control of a Vehicle

The following three systems help to control the vehicle

while driving — brakes, steering, and accelerator. At

times, as when driving on snow or ice, it is easy to ask

more of those control systems than the tires and road can

provide. Meaning, you can lose control of the vehicle.

See Traction Control System (TCS) on page 5-9,

Enhanced Traction System (ETS) on page 5-11, and

Electronic Stability Control (ESC) on page 5-6.

Adding non-dealer/non-retailer accessories can affect

vehicle performance. See Accessories and Modiﬁcations

on page 6-3.

Braking

See Brake System Warning Light on page 4-30.

Braking action involves perception time and reaction

time. Deciding to push the brake pedal is perception

time. Actually doing it 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

the 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.
