8 . Rough acceleration:
Rough acceleration can cause mechanical damage, so be sure to accelerate smoothly and gradually.
9 . How can you check hydraulic brakes?
Check hydraulic brakes by pumping the brake pedal three times before applying firm pressure to the pedal for five seconds. The pedal should not move. If it does, there may be a leak or some other problem in the braking system.
10 . During a basic vehicle control skills test, a look is when:
A driver uses a look when they open their door, leave their seated position, and walk to the back of the vehicle to check its position. During the straight line backing exercise, a driver may not exceed one look. During any other exercise, a driver may not exceed two looks.
11 . When driving in hot weather:
Because air pressure increases as air expands in the heat, it is important to monitor your tire pressure when driving in very hot weather. To prevent the engine from overheating, there must be an adequate amount of oil in the engine, as well as enough water and antifreeze in the cooling system. Antifreeze is helpful for the engine in both hot and cold weather.
12 . Which of the following is not a reason to cover cargo?
You should cover your cargo to protect people from the cargo if it spills, as well as to protect the cargo from the weather.
13 . In a dual air brake system, if one air system is very low on pressure:
In a dual air brake system, either the front or rear brakes will not be fully operable if one of the air systems gets too low on pressure. If the air pressure in either tank gets too low while you are driving, you should exit the road and park as soon as possible.
14 . When an S-cam turns inside a brake drum, the S-cam:
When a brake pedal is pressed and the S-cam is turned, the S-cam presses the brake shoes against the inside of the brake drum. This causes friction and will cause the vehicle to slow.
