Not decrease your stopping distance.

Anti-Lock Braking Systems (ABS) will help you to maintain control during hard braking. ABS will not necessarily shorten your stopping distance.

2 . In a leaf spring:

Leaves should be broken.

Leaves can be missing.

Leaves should not be broken.

When inspecting your vehicle's suspension, verify that leaf springs do not have missing or broken leaves. If at least one-fourth of the leaves in a leaf spring are missing, the vehicle will be put out-of-service until the defect is fixed.

A driver talking to another person in a vehicle

Children on the side of the road

Construction workers on the side of the road

A person sitting on a bench waiting for a bus

Drivers who are holding conversations with others may not be paying full attention to the road and may make unsafe moves. Children do not always pay attention to traffic and may dart into the road without looking. Exercise caution when driving near road workers. This helps to keep the workers and other distracted drivers safe.

4 . After a vehicle is started, warning lights and buzzers:

Should stay on for several minutes.

Should turn off within a few seconds.

Should stay on until manually turned off.

Should remain on.

After starting the engine, warning lights and buzzers should go out right away. If a light stays on, it usually indicates an issue with the vehicle.

5 . A vehicle must be equipped with all of the following, except:

A fire extinguisher.

Spare electrical fuses.

Warning devices for a parked vehicle.

A flashlight.

All commercial motor vehicles are required to be equipped with the proper emergency equipment. This may include spare electrical fuses; three red reflective triangles, six fuses, or three liquid burning flares; and at least one properly charged and rated fire extinguisher.

6 . Why are roads especially slippery right after it begins to rain?

The water mixes with oil and grease on the road.

Roads are naturally slippery.

Gravel often gets washed to the middle of the lane.

Tires are not usually designed to drive in rain.

In rainy weather, roads are often at their most slippery when the rain first begins to fall. Fresh rainwater mixes with oil and grease on the road to form a slick film. As the rain continues, this mixture will eventually wash away.

7 . What can happen if the exhaust system is not working properly?

Poisonous fumes may enter the cab.

Fumes may exit the rear of the muffler system.

Proper steering may be impossible.

Leaks in an exhaust system are extremely dangerous because they may allow toxic fumes into the cab or sleeper berth, endangering drivers and passengers.
