1 . An Anti-Lock Braking System (ABS) will:

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:

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.

3 . Which of the following is not an example of a distracted person that motorists should be worried about?

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 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 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?

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?

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