3. What is the purpose of a vehicle inspection report?

It tells the motor carrier about problems that may need to be fixed.

It ensures that the vehicle is inspected regularly.

It keeps drivers accountable for inspecting their vehicles.

It provides a plan for the next five trips.

A vehicle inspection report allows a driver to inform the motor carrier of issues that could affect the safe operation of a vehicle. If required, the driver should fill out a vehicle inspection report after every day of driving. They should make note of any issues that could affect the safety of the vehicle or that could lead to a mechanical breakdown.

4. Hydroplaning:

Rarely happens to trucks.

Usually happens when vehicles are traveling at speeds above 65 mph.

Can occur with a minimal amount of water on the roadway.

Hydroplaning is an effect in which a vehicle's tires lose traction with the surface of the road and instead glide along a layer of water. There does not have to be a large amount of water on the road for this to occur. Hydroplaning can begin at speeds as low as 30 mph.

5. A cargo cover that flaps in transit:

Is acceptable.

Allows air to get to the cargo to keep it cool.

Can tear away.

Can attract birds.

Cargo covers should not flap in the wind. A flapping cover could tear loose entirely, exposing the cargo, and potentially blocking your view or the view of other drivers.

6. When traveling long distances, you should:

Take rest breaks.

Drive as fast as possible.

Drive through the night.

To avoid becoming fatigued on a long trip, you should take a break after every 100 miles or two hours of driving. Driving through the night, or during any other time when you would normally be asleep, raises the danger of fatigue.

7. Backing with a trailer is dangerous because:

It is difficult to see behind the vehicle.

Most trucks do not have the ability to move in reverse.

Cargo may fall out of the trailer.

Backing a truck is always dangerous because the driver may not be able to see everything behind them. CMV operators should avoid backing whenever possible.
