You are in your car towing a trailer which has no brakes and you approach a long steep downhill slope. What is correct?

When towing a trailer without brakes, it is essential to take specific precautions, especially when approaching a long, steep downhill slope.

Reducing speed is crucial to maintain control of the vehicle and trailer combination. Engaging a low gear helps to utilize engine braking, reducing reliance on the vehicle's brakes, which can overheat and fail with sustained use. This is in line with German traffic regulations that emphasize safe driving practices and maintaining control on inclines.

Additionally, making allowance for the pushing effect of the trailer is important. As you descend, the trailer can push against the car, potentially leading to loss of control if not accounted for. Hence, adjusting your speed and position on the road is necessary to ensure safety.

Overall, selecting this combination is about combining speed management with an understanding of vehicle dynamics, which is crucial for safe driving under such conditions in Germany. Always remember that safety comes first, and adhering to these guidelines is essential for preventing accidents.
