In which of these circumstances would it be permissible to drive without a seat belt?

Explanation: When seat belts are fitted to your vehicle, they must be worn unless you hold a valid medical exemption certificate. People making deliveries or collections in goods vehicles are also exempt, when they're travelling less than 50 metres (162 feet).
