Transporting a flagpole in Australia: rules for long loads
Published Written by Flagpole Guides
A flagpole is often longer than the vehicle that carries it. A 6 metre pole on a ute or roof racks sticks out well beyond the back, which brings in the road rules for projecting loads. In Australia, these rules are set by the states and territories, and while the main limits are similar, the details differ. This guide uses the rules published by Transport Victoria and Queensland’s Department of Transport and Main Roads (TMR) as examples.
Overhang limits
According to Transport Victoria:
| Where | Limit |
|---|---|
| Rear overhang, car or truck | 60 per cent of the wheelbase or 3.7 metres, whichever is shorter |
| Front | 1.2 metres in front of the vehicle |
| Sides | 150 mm beyond the outermost part of either side |
| Width with load | 2.5 metres |
| Length of a car with load | 12.5 metres |
The wheelbase is the distance between the front and rear axles. According to TMR’s instruction, if a vehicle or trailer is built to the maximum dimensions, it cannot carry any projecting load. The Victorian limits are set out in parts 4 and 5 of the Road Safety (Vehicles) Regulations 2021.
Warning devices
In both states, a load that projects no more than 1.2 metres behind the vehicle and is clearly visible needs no warning device. Beyond that:
| Victoria | Queensland | |
|---|---|---|
| By day | Brightly coloured flag or piece of material of at least 30 × 30 cm at the end of the load | Brightly coloured red, red and yellow, or yellow flag of at least 450 × 450 mm at the extreme back of the load |
| At night | A red light at the end of the load | A red light visible from at least 200 metres, or at least two red reflectors |
Transport Victoria also describes a flag when the driver cannot see the overhanging load well. According to TMR, all warning devices are displayed at the very end of the load and are clearly visible to other road users.
Trailers
A long pole is often easier to carry on a trailer. According to Transport Victoria, the maximum overhang on a trailer is 3.7 metres; for trailers carrying water craft and gliders, a longer limit of 5 metres applies under conditions. The same warning rules for loads beyond 1.2 metres apply.
Securing the load
A pole that shifts in braking or cornering is a hazard for other road users, and a long pole supported at several points bends less. Telescopic or sectional poles, which come in shorter sections, avoid most of the overhang issues. More in the guide to types of flagpoles.
Delivery by the supplier
Many suppliers deliver long poles by truck. According to the Victorian Department of Education, suppliers from outside the region may add travel costs to a flagpole project. More in the guide to installing a flagpole.
Other states
New South Wales, South Australia, Western Australia, Tasmania and the territories have their own rules on projecting loads. The 1.2 metre threshold for a warning device is common, but the size of the warning flag and other details can differ; the state road authority publishes the rules that apply there. The effect of the pole’s material on its weight is covered in the guide to flagpole materials.
Frequently asked questions
How far can a flagpole stick out behind a car?
According to Transport Victoria, the rear overhang limit for a car or truck is 60 per cent of the wheelbase or 3.7 metres, whichever is shorter, and the whole vehicle with its load is no longer than 12.5 metres. The limits in other states are similar, but they are set by each state.
When does a projecting load need a flag?
In Victoria and Queensland, a load that projects more than 1.2 metres behind the vehicle carries a warning device. Transport Victoria describes a brightly coloured flag or piece of material of at least 30 × 30 cm, while Queensland’s rules call for a red, red and yellow, or yellow flag of at least 450 × 450 mm.
What is needed at night?
According to Queensland’s Department of Transport and Main Roads, a load projecting more than 1.2 metres at night carries a red light visible from at least 200 metres, or at least two red reflectors. Transport Victoria describes a red light at the end of the load.
Can a load stick out in front of the vehicle?
Only a little. According to Transport Victoria and Queensland’s Department of Transport and Main Roads, a load may project no more than 1.2 metres in front of the vehicle, measured in Queensland from the headlights, and no more than 150 mm to the side.
