Check trailer brakes and breakaway protection

  • For trailers with a gross trailer mass (GTM) in excess of 2 tonnes, the trailer service brakes do not operate immediately the trailer service hose coupling or connection is disconnected from the towing vehicle and do not remain fully applied for at least 15 minutes;
  • A truck trailer interconnecting flexible hose and coupling is not properly mated or secured;
  • For trailers with a GTM in excess of 2 tonnes the trailer brakes are not capable of being applied and released from the normal driving position;
  • Any trailer having brakes which are air or vacuum assisted is not fitted with a reservoir that is protected by a check valve;
  • Any trailer having brakes which are air or vacuum assisted is not built to provide a visible or audible warning to the driver of the towing vehicle, while the driver is in a normal driving position, of a lack of air or vacuum.
