You take over a semitrailer which you have not used before. What must you remember before attaching the semitrailer?

Your answer is correct because before attaching a semitrailer, you must check the coupling pin for wear or damage to ensure a secure and safe connection. Additionally, there must be adequate space between the driver's cabin and the semitrailer to allow for safe maneuvering and prevent collisions during turns. The tyre sizes of the semitrailer and truck tractor do not have to be the same, so that option is not required. Remembering these rules helps prevent accidents and ensures the trailer is properly connected and safe to drive.
