What is the recommended practice for using brakes when going through hills?

The recommended practice of downshifting before going over the top of a hill is crucial for maintaining control of the vehicle as you begin to descend. By downshifting, you engage a lower gear that helps utilize engine braking. This reduces reliance on the brake pedals and allows for better control on the downhill slope, minimizing the risk of overheating brake components. It also helps in maintaining a safe and controlled speed, which is essential in commercial driving due to the weight of large vehicles.

Using engine braking not only increases safety but also extends the life of brake components, as it reduces wear and tear on the brakes themselves. It’s essential for drivers to be proactive about managing their speed when approaching and descending hills, and downshifting serves as an effective method to do this. This practice integrates control and safety into the driving process, particularly in commercial driving scenarios where vehicle weight significantly affects stopping distances and handling characteristics.
