    Towing Safety

    Australian Design Rules* require any trailer with a gross mass of between 750 and 2000kg to be fitted with brakes on at least one axle. Trailers over 2000kg must be fitted with brakes on all wheels and must be able to be overridden from the driver’s seat which usually means electric operated brakes are fitted. This means the towing vehicle will require an electric brake controller to be installed.

    There are two basic means of operation for these controllers:
  • Proportional – That sense the amount of brake force being applied by the tow vehicle and engages the trailer brakes accordingly.
  • Time based - that increase the amount of trailer brake application depending on the length of time the towing vehicles brakes have been applied.

    Where the gross towing mass is over 2000kg, the trailer must also be fitted with ‘break-away’ protection that will engage the trailer’s brakes in the event it becomes unhitched from the towing vehicle.

    Some states, such as NSW also require a battery monitor unit such as Hayman Reese Smart Check (tm) to be installed so that the driver can monitor the battery powering the breakaway system from the driver's seat to ensure that the batter powering the system never fails.
