Any work on or near a road needs a traffic management plan and the equipment to implement it. That ranges from cones and signs for short-term works to variable message signs, portable traffic lights and concrete or water-filled barriers for long-term closures.
Traffic management in Australia is heavily regulated. State road authorities and councils set standards, qualification requirements and permit processes, and many sites need accredited traffic controllers in addition to equipment.
Truck-mounted attenuators (TMAs) protect workers on higher-speed roads and are typically supplied with a trained driver.
Traffic classes and sizes
The table below lists the classes of traffic equipment most commonly available for hire in Australia. Exact specifications vary by make and model—confirm dimensions, weight and capacity with the supplier before booking.
| Class | Size / spec | Typical jobs |
|---|---|---|
| Signs, cones & bollards | Standard kits | Short-term works zones |
| Arrow board | Trailer mounted | Lane closures |
| Variable message sign | Solar trailer | Advance warning and detours |
| Portable traffic lights | Pair / trailer | Single-lane shuttle flow |
| Barriers | Water-filled or concrete | Separating workers from traffic |
| Truck-mounted attenuator | TMA with driver | High-speed road protection |
How to choose the right machine
Start with the traffic plan
Your traffic guidance scheme determines what equipment is required and where. Get it prepared by a qualified person.
Check permits
Council and road authority road occupancy approvals often specify equipment and hours.
Separate people from plant
Barriers and delineation protect workers and the public. Choose barriers rated for the traffic speed.
Plan night works
Lighting towers and high-visibility equipment are needed for after-hours work.
Licences, tickets and compliance
- Traffic guidance schemes must be prepared and implemented by appropriately qualified people under the relevant state road authority framework.
- Traffic controllers require state-recognised accreditation.
- Barrier systems must be installed to manufacturer requirements for the posted speed.

What drives the cost
The hire rate is only part of the total. On short hires these items often add 20–50% to the bill—ask every supplier to quote them the same way:
- Duration on site
- Traffic controller labour
- Permits and plan preparation
- Overnight and weekend works
- TMA and driver day rates
