Compression braking, also known as engine braking, is a technique where a driver uses the engine to slow down the vehicle, which can be particularly useful for large trucks. However, there are specific scenarios where this practice may be prohibited or restricted.

The correct response highlights that compression braking is permitted unless it becomes a safety issue. This means that while truck drivers are generally encouraged to use compression braking for controlling speed and ensuring safety—especially in hilly or steep areas—they must also consider the circumstances. For instance, in certain environments, such as residential areas or zones with noise ordinances, excessive noise from compression brakes could create problems or lead to complaints from residents.

Therefore, the decision to use compression braking should prioritize safety, respecting the peace of the community, and adapting to various driving conditions. This flexibility allows drivers to exercise judgment based on their surroundings, which is essential for safe driving practices.
