What is a recommended technique for controlling speed on downhill gradients?

• A. Use the parking brake continuously
• B. Select an appropriate gear before downhill gradients
• C. Keep the vehicle in neutral
• D. Increase engine revs to maximum

Answer: (B)

Using engine braking by selecting an appropriate lower gear before you start the descent is the best way to control speed on downhill gradients. Downshifting before the slope lets the engine resist the vehicle’s motion, keeping speed steady without over-relying on the service brakes. This reduces brake heat and wear, helps prevent brake fade on long descents, and gives you more control over speed and steering. Parking brake used continuously while moving can overheat and fail, and it’s not meant for sustained downhill control. Keeping the vehicle in neutral removes engine braking entirely, leaving you to brake with the service brakes alone, which is less safe and can lead to brake overheating. Increasing engine revs to maximum would push the vehicle faster rather than slow it down.
