1 . Cargo with a high center of gravity:

Can make a vehicle likely to tip over.

Is encouraged in inclement weather.

Is required on some roads.

Cargo with a high center of gravity makes a vehicle more likely to tip over than cargo with a low center of gravity. For this reason, it is important that the weight of cargo be distributed as low as possible.

2 . 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.

3 . In low temperatures, bridges usually freeze:

After other parts of the roadway.

Before other parts of the roadway.

At the same time as other parts of the roadway.

In low temperatures, bridges usually freeze before other road surfaces. When driving in cold weather, especially when weather conditions have been wet, use special caution on bridges and overpasses.

4 . When the wheels of a trailer lock up:

The trailer will be drivable.

The trailer may swing around.

The vehicle will maintain steering.

A trailer may swing out and strike other vehicles if its wheels lock up. This is especially likely with lightly-loaded trailers.

5 . An after-trip inspection should be done:

Once a week.

Once a month.

After every trip.

You should always complete an after-trip inspection of your vehicle at the end of a trip, day, or tour of duty. Complete a vehicle inspection report, if required.

6 . When starting the engine of a truck with a trailer, you can tell that your vehicle's ABS is not working if:

The yellow light on the left rear of the trailer stays on.

The red light on the right side of the trailer flashes three times.

All the rear lights flash and then turn off.

When turning on your vehicle's engine, the lights on the dash should come on and then turn off. If the ABS malfunction light stays on, the system is not working properly. In the case of a truck with a trailer, if the yellow light on the left rear of the trailer stays on once the engine has been started, the system is not working properly.

7 . Before a trip, ensure that the fifth wheel is:

Free of grease.

Not touching the locking jaws.

Securely mounted.

When inspecting the convertor dolly, make sure all components are present and in proper working condition. Be sure to check the upper and lower fifth wheel, the air lines, and the electric lines. The fifth wheel should be properly greased and securely mounted.
