Passing Score
15. Convex mirrors:
Explanation
Many large vehicles have curved, convex mirrors. Convex mirrors allow drivers to see a wider area than flat mirrors. However, they also make objects seem smaller and farther away than they really are.
16. A driver can rely on front wheel braking to work:
Explanation
Front wheel braking is effective under all road conditions. It is unlikely that you will experience a front wheel skid, even on ice.
17. When you need to change lanes:
Explanation
Lane changes should always be executed slowly and smoothly. This will result in safer handling of your vehicle while allowing time for other drivers to react to your movements.
18. A slack adjuster should move no more than ____ from where it is attached to the push rod.
Explanation
Before a trip, you should check each slack adjuster after parking, setting wheel chocks, and disengaging the parking brake. Pull the slack adjusters to make sure that they do not move more than about one inch from where the push rod is attached. If they move more than one inch, they may be out of adjustment and will need to be fixed.
19. The most important reason to inspect your vehicle before a trip is:
Explanation
The most important reason to inspect your vehicle before a trip is to ensure the safety of yourself and others on the road. Safety inspections before every trip are required by state and federal laws.
20. What happens when a vehicle hydroplanes?
Explanation
Hydroplaning occurs when a vehicle's tires lose contact with the road surface and instead glide along on a film of water above the surface of the road.
21. When the brake pedal is depressed, air brakes work:
Explanation
After the brake pedal is pushed down in a vehicle with air brakes, it takes a half-second or more for air to flow through the lines and make the brakes work. This contrasts with hydraulic brakes used in cars and light and medium trucks, which instantly begin working when the pedal is pushed.
