Many European semi-trailers have a different type of connector (palm coupling) on the service brake airline. How would Konrad overcome this problem with his UK specification truck?

Explanation: • Leave the line disconnected as the European trailer is not compatible with the UK truck and the line need not be connected: No, this would be potentially dangerous as there would be no braking effort through the semi-trailer wheels.
• Use the shunt valve on the trailer: No.
• Take the trailer back to the depot where the mechanics can sort the problem: No, this would be illegal if the vehicle had to travel on the public road as there would be no braking effort on the semi-trailer wheels.
• Use an approved converter: Yes, this is common practice with European connectors.
