If a seat with integrated 3-point seat belt is proposed to be fitted to a vehicle which does not have Australian Design Rule 5 certification for this type of seat and seat belt configuration, engineering advice should be first obtained from a person qualified to certify that the proposed installation will conform with all relevant Australian Design Rules applicable to the vehicle type. Failure to ensure that the installation conforms to the applicable Australia Design Rules may result in failure of the seat mounting points in the vehicle in an accident and consequent possible serious injury to the driver.
