According to the CDL manual, what is the main danger of a load with a high center of gravity (cargo piled up high or heavy items loaded on top), especially in curves or during a sudden swerve?

The vehicle will get noticeably worse fuel economy

The brakes will overheat faster than with a low, evenly loaded cargo

The tires will wear unevenly on one side of the vehicle

Correct!

Correct. The manual states that the height of a vehicle's center of gravity is very important for safe handling, and that a high center of gravity means the vehicle is more likely to tip over, which it calls most dangerous in curves or when swerving to avoid a hazard.

✗

Not quite.

Wrong. Fuel economy is not the hazard the manual connects to a high center of gravity; the specific danger it describes is rollover risk in curves and swerves.

The correct answer is A: The vehicle is more likely to tip over, rather than simply skid off the road.

✗

Not quite.

Wrong. Brake overheating is associated elsewhere with overloaded vehicles and long downgrades, not specifically with where the weight sits vertically on a properly loaded vehicle.

The correct answer is A: The vehicle is more likely to tip over, rather than simply skid off the road.

✗

Not quite.

Wrong. Uneven tire wear is not the consequence the manual ties to a high center of gravity; the manual's concern is rollover and, on flatbeds, a greater chance the load will shift or fall off to the side.

The correct answer is A: The vehicle is more likely to tip over, rather than simply skid off the road.
