Key takeaways

  • TMA hire is usually priced as a package of truck, attenuator and trained operator, charged by the hour or shift with a minimum, often 6–8 hours.
  • Whether you need a TMA, and how many, is set by the traffic guidance scheme for that road, speed, traffic volume and work method.
  • Travel, night and weekend rates, standby time, extra arrow boards and impact damage terms are the lines that change the final bill most.
  • Grouping short tasks into one shift is the most reliable way to get value from a TMA minimum charge.
  • Ask every supplier the same questions so you compare total cost, not just the headline rate.

TMA hire cost in Australia is usually quoted as a package: the truck, the attenuator and a trained, licensed operator, charged per hour or per shift with a minimum that is often 6–8 hours. Travel, penalty rates, standby and damage terms come on top. Prices vary widely by supplier and job, so compare written quotes built from the same scope.

This guide is for builders, civil contractors, councils and traffic control companies who need to hire a truck-mounted attenuator (TMA) and want to understand what they are paying for. It covers what drives the price, the operator requirements, how minimum charges work, a worked example of a night patching job, and a checklist for comparing quotes.

What a TMA hire actually includes

A truck-mounted attenuator is an energy-absorbing unit fitted to the back of a heavy truck. It protects workers and stationary vehicles from errant vehicles approaching the work area. Our guide to the truck-mounted attenuator explains how it works and where it is used.

When you hire one, the price usually covers several things:

ComponentWhat it means for cost
The truckA heavy rigid vehicle with registration, insurance, maintenance and fuel
The attenuator unitPurchase cost, inspection and certification, spare parts
The operatorTraffic control training plus the correct heavy-vehicle licence, paid under an award with penalty rates
Warning devicesLights and often an arrow board or message board on the truck
Compliance overheadsInspections, certification after any impact, records
AvailabilityA specialist truck sitting in a yard when it is not booked

That is why a TMA costs more per hour than a traffic controller. You are paying for a heavy vehicle, a specialist safety device and a licensed operator at once.

Some suppliers offer a trailer-mounted attenuator instead, towed behind a suitable vehicle. It is a different device with different uses and limits. Our guide to the trailer-mounted attenuator explains the difference. Only use the type the plan specifies.

Who can operate a TMA

TMA operators need appropriate traffic control training and the correct heavy-vehicle licence for the truck. The unit itself must be inspected and certified according to the manufacturer and the relevant guideline, and after any impact. For heavy vehicle duties, including Chain of Responsibility, see the National Heavy Vehicle Regulator.

If you are a traffic control company hiring a unit without an operator, check that your own driver holds the right licence and training, and that the supplier has briefed them on the specific unit. If you are a builder hiring a TMA with an operator, ask the supplier to confirm the operator's licence and training in writing.

What drives the price

The hourly or shift rate is only the start. These factors change the total most.

Time band

Night, weekend and public holiday work attracts higher rates because operators are paid penalty rates under their award. A lot of TMA work happens at night on busy roads, so check you are comparing night rates, not day rates.

Minimum charges

Minimum charges for vehicles and operators are commonly 6–8 hours. A one-hour inspection protected by a TMA still costs the minimum. Our explainer on traffic control minimum hours explains why minimums exist.

Travel

TMAs are based at a limited number of depots. Travel time, kilometres and tolls from the depot to your site are often charged, and some suppliers start the clock when the truck leaves the yard.

Number of units

Mobile works on higher-speed roads can need more than one protection vehicle. Some static closures need a TMA on each approach. The plan decides how many, and each one carries its own minimum.

Standby and waiting

If the TMA is set up but your work has not started, waiting time usually applies. If the job is called off on the day, cancellation terms apply.

Impact and damage

If the TMA is hit, the attenuator may need repair or parts, and the unit must be inspected and certified before it returns to work. Ask who pays and whether a replacement unit is available.

When you need a TMA (and when the plan says you do not)

You do not decide to add or remove a TMA on price alone. Whether one is needed, and where it sits, comes from the traffic guidance scheme prepared by a suitably qualified person, based on the road's speed, traffic volume, the work method and how exposed workers are. Requirements differ between states.

In NSW, Transport for NSW's TS 05492:1.0 Traffic Control at Work Sites, which replaced the TCAWS manual on 25 June 2026, added requirements on crash attenuators. Check which document your project specifies and confirm current requirements with Transport for NSW or your state road authority. For the national guide, see Austroads.

If you think the plan specifies more protection than you need, talk to the plan author. Do not remove a TMA from the site because the budget is tight. This article is general information, not engineering advice.

Worked example: night patching on an arterial road

Here is how a typical TMA booking plays out. This is an example scenario with made-up figures to show the process and arithmetic.

The job. A council maintenance crew needs to patch six potholes in the kerbside lane of a multi-lane arterial road at night. The TGS specifies mobile works with a TMA behind the patching truck as it moves between locations.

Step 1: the booking. The council's works supervisor gives the traffic provider the road, the six locations, the start time and the expected duration of about three and a half hours. The provider quotes a TMA with operator, a traffic control vehicle and the night rates.

Step 2: the pre-start. On arrival, the TMA operator completes the vehicle and attenuator pre-start: lights and arrow board working, attenuator in the correct deployed position, no visible damage to the impact face, and the current inspection record in the cab. The team leader runs the SWMS sign-on and briefing.

Step 3: the briefing and radio calls. The briefing covers the order of locations, where the TMA will sit relative to the work at each stop as set by the TGS, and the radio calls:

  • "Moving to location two" from the team leader before the convoy moves.
  • "TMA in position" from the operator before any worker leaves the truck.
  • "Hold, vehicle approaching fast" from anyone who sees an erratic driver.

Step 4: what goes wrong. At location four, a driveway and a parked car mean the TMA cannot sit where the TGS shows it. The operator calls it on the radio. The team leader stops the work, checks the plan, and the crew skips location four rather than improvising a position. The skipped location and reason are recorded, and the supervisor schedules it for another night with a parking restriction in place.

Step 5: the bill (made-up figures). Suppose the TMA package is $100 per hour and the minimum is 8 hours. The job takes 3.5 hours, so the charge is 8 × $100 = $800, not 3.5 × $100 = $350. Travel is added at the supplier's stated rate.

The lesson. The council could have bundled the patching with another task on the same road, such as replacing damaged guide posts, if the plan covered both tasks, and used more of the 8 hours. Next time, the supervisor groups tasks so the minimum is used, not wasted.

What gets recorded. TMA pre-start, SWMS sign-on, start-of-shift inspection, each location's start and finish time, the skipped location and reason, end-of-shift inspection, and the docket signed by the council supervisor.

What to send a TMA supplier

A supplier can only quote accurately if it knows the job. Send this with every request:

  • The road, suburb and direction of travel, and who manages the road.
  • The TGS, or at least the plan author's note on how many TMAs are needed and where.
  • Whether the work is static (one location for the shift) or mobile (moving between locations).
  • Date, start time, expected duration and whether it is a night or weekend shift.
  • Any staging or waiting, such as materials arriving after the start.
  • Access issues: low trees, narrow streets, weight limits or a long distance from the depot.
  • Who on your side will sign the docket.

If you are booking through a traffic control company, it will usually arrange the TMA as part of its quote. Ask for the TMA to be shown as its own line, with its own minimum, so you can see what it costs.

How to keep TMA costs under control

  • Group tasks. Put several jobs on the same road or area into one shift to use the minimum.
  • Give accurate times. Tell the supplier the real start time and duration, including any waiting for materials.
  • Check the site beforehand. Parked cars, driveways and roadside obstacles can stop a TMA taking its position.
  • Book early for nights. TMA availability is limited and busy periods fill quickly.
  • Agree cancellation terms. Rain or a failed material delivery can cancel a night; know what you pay.
  • Use the dockets. Signed dockets with start and finish times make the invoice easy to check.

Frequently asked questions

How much does it cost to hire a TMA in Australia?

TMA prices vary widely by supplier, location, time band and job, so there is no single market rate. Most suppliers charge per hour or per shift for the truck, attenuator and operator together, with a minimum that is often 6 to 8 hours. Travel and penalty rates are usually extra. Get written quotes from the same scope.

Does TMA hire include an operator?

Usually, yes. Most TMAs are supplied with an operator who has the appropriate traffic control training and the correct heavy-vehicle licence for the truck. Some suppliers hire units to traffic control companies that have their own qualified operators. Confirm in writing who is operating the unit and what training and licence they hold.

What is the minimum hire for a truck-mounted attenuator?

Minimum charges for vehicles and operators are commonly 6 to 8 hours, even if the task is shorter. The minimum covers the supplier's cost of committing a truck and driver for the shift. Ask what the minimum is, whether travel counts toward it and how time beyond the minimum is billed.

When is a TMA required at road works?

It depends on the traffic guidance scheme, which considers the road's speed, traffic volume, the work method and how exposed workers are. State requirements differ and change over time; in NSW, TS 05492:1.0 added requirements on crash attenuators. A suitably qualified person decides when a TMA is needed for your job.

Who pays if a hired TMA is hit?

That depends on the hire terms, so ask before you book. After any impact the unit must be inspected and certified before it is used again, and the attenuator may need repair or parts. Suppliers handle this differently, and some pursue the at-fault driver. Get the impact and damage terms in writing.
