Aggregate Trailer Mass (more commonly referred to as ATM), is the combined weight of a fully-loaded trailer when it is not coupled to a towing vehicle. In South Australia, there are laws in place with regard to ATM and load limits, as well as regulations with regard to a trailer’s ATM and its braking system and capabilities.
Therefore, whether you are towing a single axle or tandem axle trailer, if you plan to tow loads with an ATM above 2000kg, you will need to upgrade from our standard trailer configuration.
