When should you test the brakes to ensure they are functioning normally?

Testing the brakes as soon as the vehicle is underway is crucial for several reasons. When a truck starts moving, it’s important to ensure that the braking system is functioning properly in real-world conditions. This allows the driver to assess how the brakes respond while the vehicle is in motion, providing an immediate check on responsiveness, effectiveness, and any unusual sounds or feedback that might indicate a problem.

Conducting the brake test only after the engine is started or when arriving at a destination would not provide sufficient information about the brake system's performance while driving. Waiting for scheduled inspections does not account for everyday safety needs, as issues with the brake system can develop between those checks. Therefore, verifying brake functionality right after the vehicle is in motion is a proactive approach to ensure safe operation on the road.
