44 . During the basic vehicle control skills test:
Excessive pull-ups are acceptable in the opinions of some test administrators.
During the basic vehicle control skills test, a pull-up will be scored any time an applicant stops and pulls forward to gain a better position. Stopping without changing direction will not. An excessive number of pull-ups will count as errors.
45 . If operating a school bus, you are considered to be driving under the influence of alcohol if you have a minimum blood alcohol content (BAC) of:
0.1 percent.
A person operating a school bus is considered to be driving under the influence of alcohol if their blood alcohol concentration (BAC) is 0.02 percent or higher.
46 . If an Anti-Lock Braking System (ABS) is equipped on a trailer but not on a tractor:
The tractor and trailer can still be used together.
A vehicle being equipped with anti-lock brakes on only the tractor or only the trailer provides additional control during braking.
47 . When inspecting engine compartment belts during the vehicle inspection test:
The applicant must identify which items are not belt-driven, if any.
When checking the engine compartment during the vehicle inspection test, you must check the power steering, water pump, alternator, and air compressor belts. In addition to cracks and frays, you should check the belts for snugness, allowing up to three-quarters of an inch of play at the center of each belt. If any of these items are not belt-driven, you must identify them and ensure that their components are operating properly, are not damaged or leaking, and are mounted securely.
48 . If a tire fails, the driver should:
Accelerate.
If a tire fails, braking could cause a loss of control. Unless braking is necessary to avoid a hazard, you should stay off the brakes until your vehicle has slowed considerably. Only then should you brake very gently, pull off the road, and stop.
49 . To correct a drive-wheel braking skid, a driver should do all of the following, except:
Accelerate.
To correct a drive-wheel braking skid, you should first remove your foot from the brake pedal to allow the locked wheels to begin rolling again. Quickly steer in the direction you want to go, then countersteer to prevent your vehicle from skidding in the opposite direction.
50 . When the brake pedal is pushed down, air brakes work:
Only if it is warm outside.
Because air takes time to flow through the air lines to the brakes, air brakes cannot begin working instantly. There is often a brake lag of at least one-half of a second between the moment the brake pedal is pressed and the moment the brakes begin to work.
