What is an important procedure after coupling a trailer?

Testing the brakes before driving off is an essential procedure after coupling a trailer because it ensures that the braking system is functioning correctly. Proper brake operation is crucial for safety, particularly when hauling heavy loads. After coupling, the brakes should be tested to confirm that the trailer’s brake system engages as intended when the vehicle driver applies the brake pedal. This procedure helps prevent accidents on the road, ensuring that both the truck and trailer can stop effectively.

Ensuring that the brakes are fully operational can also help reduce the risk of wear on the vehicle’s brake components, providing a longer lifespan for both the truck and trailer and maintaining overall safety standards. Therefore, making testing the brakes a priority is fundamental to safe operation.
