A single axle caravan with overrun brake is parked on a downhill slope. How do you have to secure it to prevent it from rolling away?

To safely park a single axle caravan with an overrun brake on a downhill slope, you must use the parking brake and place wheel chocks in front of the wheels. The parking brake prevents movement by locking the wheels, but on a slope, it’s essential to add wheel chocks for extra security, especially for trailers and caravans. Placing chocks only in front (when facing downhill) gives direct support against rolling. Putting a chock both in front and behind the same wheel, as described in answer 3, is unnecessary and does not provide increased safety compared to properly blocking both wheels in the rolling direction. Always use both the parking brake and appropriate chocks to prevent the trailer from rolling away, as required by German traffic regulations. This is a common safety practice for all trailers on slopes.
