Passing Score 40

1. When transporting a load, the cargo should be inspected:

Only at the beginning of a drive.

Only after driving a long distance.

After every break.

Cargo and its securing devices must be inspected before starting a trip. After beginning a trip, the driver should check the load and securing devices within the first 50 miles on the road, every three hours or 150 miles traveled, and after every break.

2. When using a fire extinguisher to put out a fire, you should:

Stay as far away as possible from the flames.

Aim at the flames.

Use any extinguisher on every type of fire.

Stay as far away from a fire as possible and aim your fire extinguisher at the source or base of the fire, not at the flames. It may be appropriate to extinguish certain fires with water. If you are unsure of how to treat a specific fire, you should wait for trained firefighters to arrive.

3. When in heavy traffic, the safest driving speed is:

Slower than the speed being driven by surrounding traffic.

The same speed being driven by surrounding traffic.

Faster than the speed being driven by surrounding traffic.

In heavy traffic, it is safest to travel at the same speed as other vehicles. If two vehicles continue to drive in the same direction at the same speed, they cannot hit each other.

4. Blocking is used to:

Prevent cargo from shifting.

Prevent cargo from being loaded too high.

Prevent cargo from being unloaded too quickly.

Blocking is used in the front, in the back, and/or on the sides of a piece of cargo to keep it from sliding while the vehicle is in motion.

5. When loading a trailer, you should:

Place as little weight as possible over the axles.

Place a well-balanced amount of weight over the axles.

Not be concerned with how the weight is distributed.

A load of cargo must be properly balanced. Placing too much weight over an axle can damage the axle and make it more difficult for you to steer. Placing too little weight over an axle can cause poor traction, also leading to difficult handling.

6. During the driving test, when asked to make a lane change:

You should not be concerned with other motorists.

You should use your turn signal and change lanes when safe.

You should make the lane change as quickly as possible, even if that means cutting off another driver.

When asked to make a lane change during the on-road driving test, you should make the proper traffic checks, use your turn signal, and smoothly change lanes when it is safe to do so.

7. Alcohol is removed from the body:

By exercising.

At a fixed rate.

More quickly if the person stays awake.

The liver removes alcohol from the body at a fixed rate. Despite popular belief, tricks like drinking coffee or taking a cold shower will not speed up the process. The only way to become sober is to allow your body the time it needs to remove the alcohol from your system.
