43 . On slippery roads, you should:
Accelerate and decelerate frequently.
Make sure to drive slowly and smoothly on slippery roads. Do not pass slower vehicles unless it is necessary to do so. Avoid frequently changing your speed under such conditions.
44 . An applicant will be denied a hazardous materials endorsement if they:
Already have a driver license.
Your application for a hazardous materials endorsement can be denied, or your existing endorsement canceled, if you do not have legal permanent status in the United States; you renounce U.S. citizenship; you are wanted for, under indictment for, or convicted of certain felonies; you are judged mentally incompetent or are involuntarily committed to a mental institution; or you are deemed by the Transportation Security Administration to pose a security threat.
45 . Before starting down a hill, you should:
Move into the left lane.
Always downshift before beginning to drive downhill. Take the hill at a speed that does not require you to overuse your brakes.
46 . Distracted driving:
Is encouraged on uncrowded roads.
Mental distractions can be just as dangerous as physical ones. It is possible for a person to look right at a hazard on the road but fail to notice it because their thoughts are occupied by something else.
47 . If someone pulls out in front of you and you cannot stop to avoid a crash, you should:
Accelerate.
If another vehicle pulls out in front of you, it is appropriate to brake as long as there is room for your vehicle to stop while you are using the appropriate braking technique. However, if you do not have room to stop, swerving may be a safer response.
48 . Test the low pressure warning signal:
Before every trip.
It is essential that your low pressure warning light function properly. After allowing the system to charge, you can test the warning signal by rapidly applying and releasing the brake pedal. This will release air from the braking system and the warning signal should come on when pressure drops to a dangerous level.
49 . Using an Anti-Lock Braking System (ABS):
Provides more control.
An Anti-Lock Braking System (ABS) helps prevent wheel lockup during hard braking. While it provides better control, it does not necessarily shorten a vehicle's stopping distance.
50 . Exceeding the number of pull-ups allotted for a single exercise will result in:
An extra point against your score.
A driver is allowed to use two pull-ups without penalty during any skills test exercise, aside from the straight line backing exercise, during which only one pull-up is permitted. Exceeding the number of permitted pull-ups during a single exercise will result in automatic failure of the basic vehicle control skills test.
