What is a recommended action for drivers when approaching steep descents?

• A. Accelerate to maintain control
• B. Shift to a low gear before descending
• C. Trust the brakes to handle all descent challenges
• D. Ignore speed limits posted on the hill

Answer: (B)

Shifting to a low gear before descending is a recommended action for drivers approaching steep descents because it allows the vehicle to take advantage of engine braking. This technique helps to maintain a safe speed without over-relying on the brakes, which can lead to overheating and reduced braking efficiency. By using lower gears, the engine provides resistance that slows down the vehicle naturally, making it easier to control on a steep incline. Other actions, such as accelerating to maintain control, can lead to an uncontrollable situation as speed increases on a downhill slope. Relying solely on brakes can cause them to overheat and fail, especially on long descents. Ignoring posted speed limits is both unsafe and illegal, as these limits are established to ensure the safety of all road users in challenging conditions.
