What is required at a "truck stop here" sign before a steep downgrade?

Before approaching a steep downgrade, it is imperative to inspect the braking system, as this is critical for ensuring safe vehicle operation. Properly functioning brakes are essential when navigating downhill slopes, where gravity can significantly increase speed and make it more challenging to control the vehicle. A thorough inspection of the braking system would involve checking brake fluid levels, the condition of brake pads, and the functionality of both service and emergency brakes.

While inspecting fuel levels, checking cargo load, and testing engine performance are important tasks in their own right, they do not directly address the immediate safety concerns posed by descending a steep grade. The braking system specifically ensures that the vehicle can maintain safe speeds and respond appropriately to various driving conditions encountered during a descent. Proper brake maintenance can prevent accidents and ensure the safety of both the vehicle and other road users.
