The current legislation requires that any minibus, bus or goods vehicle of gross vehicle mass not exceeding 2500 kg, first registered on or after 1 January 1979, or of gross vehicle mass not exceeding 3 500 kg, first registered on or after 1 January 1987, must have at least a harness belt or three-point belt fitted for the driver, and if the front seat has seating accommodation for other persons, must have at least one other harness belt or three-point belt fitted.
