On a downhill with a manual transmission, which gear helps manage speed through engine braking?

• A. Higher gear
• B. Lower gear
• C. Neutral
• D. Park

Answer: (B)

Control speed on a downhill by using engine braking, which you get by downshifting to a lower gear in a manual transmission. When you shift into a lower gear and keep the throttle partly closed, the engine turns faster and its internal resistance (compression and vacuum) creates a braking effect. This helps you slow the vehicle without overusing the brakes, reducing brake fade on long descents. Drive in a lower gear before or during the descent and avoid staying in neutral, which removes engine braking entirely and makes it harder to control speed. Also don’t downshift to a gear that would over-rev the engine; up and downshifting smoothly keeps RPMs within a safe range.
