Commercial Driver License (CDL) Class B Practice Test

How can a driver best manage a heavy load while stopping?

1. By braking suddenly

2. By using only primary brakes

3. By applying gradual braking force

4. By using engine braking only

The correct answer is: By applying gradual braking force

A driver can best manage a heavy load while stopping by applying gradual braking force. This method allows for a smoother and more controlled stop, which is particularly important when dealing with heavy loads. Sudden braking can cause the vehicle to skid or tip over, as the weight distribution changes abruptly. Using gradual braking helps in maintaining traction and stability, allowing the driver to maintain control of the vehicle. Additionally, applying brakes gradually helps in reducing the risk of brake fade, which can occur when the brakes become overheated due to excessive pressure. It also provides ample time for the driver to assess the environment and make necessary adjustments to their stopping distance. While engine braking can be beneficial, it is not sufficient on its own for managing the complexity of stopping a heavy load, which requires a combination of techniques including proper use of the primary brakes.
