What could happen if the trailer is too high when attempting to couple?

When coupling a trailer, proper alignment is crucial for a secure connection. If the trailer is positioned too high relative to the fifth wheel or coupling mechanism on the tractor, this can lead to misalignment. A misaligned connection may not engage properly, which can result in the trailer unexpectedly disconnecting while in transit. This scenario poses significant safety risks, including potential damage to the vehicle and dangers to other road users.

For example, if the trailer is not correctly engaged, it could detach during turns or when encountering obstacles in the roadway. Therefore, ensuring that the height of the trailer aligns appropriately with the tractor's coupling system is essential for safe operation and preventing accidents.
