How do you secure a car with a manual gearbox against rolling away on a downhill slope?

To secure a car with a manual gearbox against rolling away on a downhill slope, it is essential to take specific steps in accordance with German traffic regulations.

Engaging the parking brake is critical because it provides an additional level of security, preventing the vehicle from rolling unexpectedly. Additionally, engaging first gear or reverse gear is equally important as it locks the transmission, further ensuring that the car cannot move.

Putting the gear lever in the neutral position is not advisable in this situation, as this would leave the vehicle susceptible to rolling if the parking brake were to fail. The combination of applying the parking brake and engaging a gear creates a robust safety mechanism that aligns with German traffic safety standards, emphasizing the importance of preventing accidents and ensuring vehicle stability when parked on slopes.
