Difficulty: MediumTowing Equipment and Safety Checks (Caravans & Trailers)

You are coupling a braked trailer to your car. In which order should you carry out these safety and hitching procedures before driving onto the public road?

  1. 1Lower the trailer hitch onto the towball until the coupling clicks and locks firmly into place.
  2. 2Attach the breakaway cable to the car's dedicated fixing point and plug in the electrical lighting cable.
  3. 3Wind up the jockey wheel fully and secure the clamp in its raised travelling position.
  4. 4Release the trailer handbrake and check that all trailer indicator, brake, and tail lights operate properly.

Answer

1. Lower the trailer hitch onto the towball until the coupling clicks and locks firmly into place. 2. Attach the breakaway cable to the car's dedicated fixing point and plug in the electrical lighting cable. 3. Wind up the jockey wheel fully and secure the clamp in its raised travelling position. 4. Release the trailer handbrake and check that all trailer indicator, brake, and tail lights operate properly.
The correct procedure begins with lowering and locking the trailer coupling onto the towball. Next, the safety breakaway cable and electrical connector are attached to provide emergency braking and lighting power. Following this, the jockey wheel is fully retracted and locked in its raised transit position. Finally, the trailer handbrake is disengaged and the lights are verified before setting off.

Step-by-Step Solution

1
Lower the hitch head onto the vehicle's towball
The coupling handle latches and locks over the ball, securing the trailer to the car.
Establishing the primary physical connection between the vehicle and trailer is necessary before securing secondary systems.
2
Connect the emergency breakaway cable and 13-pin/7-pin electrical plug
The emergency braking fail-safe is engaged and electrical circuits are completed.
The breakaway cable must be attached while the trailer is stationary so it can apply the trailer brakes if coupling fails, and electrical cables power road lights.
3
Retract and clamp the jockey wheel
The jockey wheel is locked out of contact with the ground in its transit position.
If the jockey wheel is not wound up and securely locked, it could catch on road irregularities, causing severe damage or loss of control.
4
Disengage the trailer parking brake and inspect all exterior lighting
The trailer wheels are free to rotate and all statutory signalling lights are confirmed working.
The handbrake must only be released once the hitch and jockey wheel are secure, followed by a full walkaround light check to comply with road safety regulations.
