A.T.M. (Aggregate Trailer Mass)

This is the weight on all the wheels, plus the ball weight, plus your personal load, including water, gas and

any accessories you fit. The total of all of these weights is the Aggregate Trailer Mass (A.T.M.)

G.T.M. (Gross Trailer Mass)

This is the weight on all the wheels, plus your personal load, plus water, gas and any accessories you fit.

The total of these weights is the Gross Trailer Mass (G.T.M.)

TARE (Tare Mass)

This is the weight on all the wheels, plus the ball weight. The total of these weights is the TARE. The TARE

does not include water and gas as these items form part of your personal payload.

PERSONAL LOAD

Personal load means the weight of all items added to your trailer or caravan such as - clothes, food,

hoses, crockery, cutlery, tools, water, gas and any accessories you fit (ie. TV set, radio, awning, push

bike, additional spare wheels etc.). The total weight of all items added to your caravan or trailer is the

Personal Load.

To do so could overload the suspension, chassis or frame and thereby cause an accident by component

failure.

If in doubt about the weight of your caravan or trailer you should weigh it when fully loaded on the road

including full water tank(s) and gas cylinder(s). This can be done at a Public Weighbridge (check Yellow

Pages for locations).

HOW TO CALCULATE WHAT PERSONAL LOAD YOU CAN CARRY IN YOUR TRAILER OR CARAVAN

To calculate the maximum load you can safety carry in your trailer or caravan, take the TARE (as stamped

on the trailer plate), from the aggregate trailer mass. A.T.M. (as stamped on the trailer plate). The A.T.M.

minus the TARE equals the maximum load your trailer or caravan can carry.
