You are pulling a trailer with overrun brakes. What must you be aware of?

When pulling a trailer with overrun brakes, you need to know that reversing is generally not possible or is very difficult. Overrun brakes are designed to activate when the towing vehicle slows down, which works well when moving forward but causes the brakes to engage and lock when backing up. That’s why answer 1, which says you cannot reverse, is correct. Always remember: with trailers using overrun brakes, reversing is a problem because the brake mechanism engages as you push the trailer backward. This is important for safe maneuvering and planning when towing such trailers.
