You are driving a motor vehicle with a manual gearbox. What must you consider when you see this road sign?

This road sign warns of a steep downhill gradient of 10%. When driving a vehicle with a manual gearbox on such slopes, you must be aware that the braking distance will be longer because gravity increases your speed downhill. Additionally, prolonged use of the brakes can cause them to overheat, which reduces their effectiveness, meaning the braking response diminishes if you brake continuously for a long time.

Therefore, it is important to use engine braking by selecting a lower gear to help control your speed and reduce reliance on the brakes alone. This is why option 3 is incorrect—coasting in neutral or with no gear engaged reduces engine braking and can lead to poorer braking response on steep slopes. Always keep a gear engaged to utilize engine braking and maintain control.
