Key takeaways
- Traffic control fleet costs fall into three groups: ownership, running costs, and the hidden costs of compliance, damage and downtime.
- Turn every asset's annual cost into a cost per job day using its real utilisation, not the number of days it could have worked.
- TMAs carry the highest cost per hour: a heavy vehicle, an attenuator that must be inspected and certified, licensed operators and repairs after any impact.
- Trailer-mounted plant such as arrow boards and VMS boards looks cheap until batteries, theft, damage and towing rules are counted.
- Use your own numbers: fleet costs vary hugely by finance terms, location, work mix and how well vehicles are looked after.
Traffic control fleet costs are the full cost of owning and running your utes, truck-mounted attenuators and trailer-mounted plant: finance or depreciation, registration, insurance, fuel, tyres, servicing, fit-out, inspections, damage and downtime. The figure that matters is cost per job day, worked out from actual utilisation, because that is what your rates have to recover.
Vehicles are usually the second-biggest cost in a traffic control business after labour, and the easiest to underestimate. A ute that "costs" its lease payment actually costs that plus everything listed below, spread across the days it worked rather than the days it existed. This guide shows how to build that number for each asset type.
The three layers of fleet cost
Every asset in the fleet has the same three layers. Most operators count the first, half-count the second and ignore the third.
| Layer | What it includes | Easy to miss |
|---|---|---|
| Ownership | Purchase or lease, finance interest, depreciation, fit-out | Fit-out replacement during the vehicle's life |
| Running | Fuel, tyres, servicing, repairs, registration, insurance, tolls, telematics | Kerb and gravel tyre damage, cleaning, tolls not recharged |
| Compliance, damage and downtime | Inspections, certifications, licensing, sign damage, theft, hire-ins during repairs | Office time, idle days, post-impact repairs |
Traffic control utes
The ute is the workhorse: it carries the crew, signs, cones, stands, bats, radios and first aid kit, and often tows an arrow board. A well set-up vehicle saves time on every job; our guide to traffic control ute set-up covers what to carry.
Ownership and fit-out
Beyond the vehicle itself, budget for:
- Beacons, work lights and wiring that meet your clients' and road authorities' requirements.
- Sign racks, cone storage, a cage or tray body, tie-down points and load restraint.
- Tow bar and electric brake controller if it tows plant.
- Livery, reflective markings, two-way radio installation and a fire extinguisher.
Fit-out components wear out and get damaged faster than the vehicle. Include their replacement over the vehicle's life, not just at purchase.
Running costs
Registration and CTP insurance, comprehensive motor insurance, fuel, tyres, servicing and repairs, tolls and telematics. Traffic control work is hard on vehicles: lots of idling with beacons and lights running, short trips between sites, kerbs, gravel shoulders and heavy loads. Service schedules written for normal driving may not suit.
Tax and private use
If workers take utes home, fringe benefits tax may apply depending on how the vehicle is used. Some exemptions exist for certain commercial vehicles where private use is limited. Ask your accountant before you set a take-home policy.
Loading and towing
Every ute has a gross vehicle mass and a towing capacity. A ute full of signs, sandbags and water plus three people, towing an arrow board, can be closer to its limits than drivers realise. Overloading voids insurance and creates real braking and handling risk. Weigh a typically loaded ute once so you know.
Truck-mounted attenuators: the costliest asset per hour
TMAs protect crews and stationary vehicles from errant traffic, and for some work they are required by the TGS or the project. They are also the asset most likely to sink a fleet budget. Our guide to truck-mounted attenuators covers when they are needed and how they work.
The cost layers for a TMA:
- The truck. Usually a heavy vehicle, with heavier registration, insurance, servicing and tyre costs than a ute.
- The attenuator. A significant purchase in its own right, mounted and maintained to the manufacturer's requirements.
- Inspection and certification. TMA units must be inspected and certified according to the manufacturer and the relevant guideline, and after any impact. Budget time and money for scheduled checks and for an unscheduled one after every hit.
- Impact repairs and downtime. After an impact the unit is out of service until it is inspected, repaired and recertified. Without a spare, you hire in or lose the work.
- Operators. TMA operators need appropriate traffic control training plus the correct heavy vehicle licence. Holding licensed operators on the roster costs money even when the truck is idle.
Heavy vehicle law
A vehicle with a gross vehicle mass over 4.5 tonnes is a heavy vehicle under the Heavy Vehicle National Law, which applies in every state and territory except Western Australia and the Northern Territory. That brings obligations for registration, mass and dimension limits, vehicle standards and maintenance, and chain of responsibility duties for the company and its managers, not just the driver. Trucks over 12 tonnes GVM are fatigue-regulated, with work and rest hour limits and work diary requirements for some work. The NHVR explains the current rules.
In practice, chain of responsibility costs time rather than money: maintenance records you can produce on request, allocations that do not force a TMA driver to rush between a night shift and a morning start, checked load restraint for the attenuator and any carried equipment, and someone in the office who owns heavy vehicle compliance. Build that time into your overheads.
Licence classes are set by the state licensing authority; for NSW, check with Transport for NSW. The class depends on the truck's mass and axles, so check the compliance plate rather than assuming.
Utilisation decides the economics
A TMA that works two days a week costs almost as much to own as one working five. Clients often pay TMA minimums of 6 to 8 hours, but that only helps when the truck is booked. Track your TMA days for several months before buying another, and compare with the cost of hiring for peaks. Our guide to hiring versus buying equipment walks through that decision.
Trailers and trailer-mounted plant
Arrow boards, VMS boards, lighting towers, sign trailers and portable traffic signals are often the cheapest assets to buy and the most annoying to run.
- Registration and roadworthiness: each trailer needs registration, working lights, brakes where required and regular checks of tyres, bearings and couplings.
- Power: solar panels and batteries degrade. A board that dies overnight is a safety failure, not just a maintenance issue.
- Software and messages: VMS boards need correct messages programmed and checked, sometimes remote monitoring subscriptions.
- Theft and vandalism: boards left on site overnight get damaged, tagged or stolen. Count your losses honestly.
- Towing: a combination is caught by heavy vehicle rules if the towing vehicle's GVM or the trailer's aggregate trailer mass is over 4.5 tonnes. Check both plates.
How to calculate cost per job day
Here is the method for one asset. Repeat it for each vehicle or plant type.
| Step | Calculation | Example only: one ute |
|---|---|---|
| 1 | Annual ownership: depreciation or lease, plus finance interest | $18,000 |
| 2 | Annual fixed running: rego, CTP, insurance, telematics | $4,500 |
| 3 | Annual variable running: fuel, tyres, servicing, repairs | $16,000 |
| 4 | Annual fit-out, damage and hire-in allowance | $3,500 |
| 5 | Total annual cost (1 to 4) | $42,000 |
| 6 | Days available for work in a year | 240 |
| 7 | Utilisation: share of available days it actually worked | 75% |
| 8 | Job days (6 × 7) | 180 |
| 9 | Cost per job day (5 ÷ 8) | about $233 |
Now the useful part. If utilisation rises to 85%, job days become 204 and cost per job day falls to about $206, without spending anything. If it falls to 60%, cost per job day rises to about $292. Fleet profitability is mostly a utilisation question.
To convert to an hourly figure, divide by the average billable hours the asset recovers per job day. The free charge-out rate builder lets you add the result to your labour and overhead costs so your rates recover the fleet properly.
Own, lease or hire
| Option | Suits | Watch for |
|---|---|---|
| Buy outright | Steady, predictable demand; strong cash position | Capital tied up; resale value; idle days |
| Finance or lease | Growing operators who need vehicles now | Fixed repayments in quiet months; end-of-term conditions |
| Hire | Peaks, trials, specialist plant used occasionally | Higher daily cost; availability in busy seasons |
Many operators own utes, hire TMAs until demand is proven and mix owned and hired boards. Revisit the mix every year with real utilisation data.
Keeping fleet costs under control
- Daily pre-start checks. Lights, beacons, tyres, load restraint and plant batteries, recorded with the shift. Problems found in the depot are cheaper than problems found on a highway shoulder.
- A maintenance calendar. Services, registrations, TMA inspections and trailer checks in one place with reminders.
- Damage reporting without blame. If crews hide scrapes and broken signs, small repairs become big ones.
- Smart allocation. Send the nearest suitable vehicle; avoid empty runs between depots. Plan breakdown cover in advance; see our vehicle breakdown response checklist.
- Recharge what you can. Tolls, extra travel, after-hours plant and damage caused by others should be in your terms and on your invoices.
Next steps
Build the cost-per-job-day table for your three most common assets and compare it with what your rates recover. When utilisation, not price, is the problem, fix allocation before buying more. TrafWise records which vehicles and plant went to each job on the signed docket, so utilisation comes from real records instead of guesswork.
Frequently asked questions
How much does it cost to run a traffic control ute?
It depends on purchase or lease cost, fit-out, finance, insurance, registration, fuel, kilometres travelled, servicing and damage. Rather than rely on a generic figure, add up the annual cost of each ute and divide by the days it actually worked. That cost per job day is what your pricing must recover.
Is a TMA truck a heavy vehicle?
Most TMA trucks have a gross vehicle mass above 4.5 tonnes, which makes them heavy vehicles under the Heavy Vehicle National Law where it applies. That brings registration, licensing, maintenance and chain of responsibility obligations, and trucks over 12 tonnes are fatigue-regulated. Check the vehicle's plate and the rules with the NHVR.
Should a traffic control company buy or hire TMAs?
Buying makes sense when you have steady, predictable TMA work that keeps the unit busy. Hiring suits occasional or uncertain demand, because you avoid capital, certification and idle time. Track your actual TMA days for a few months before deciding, and include operator availability, not just the truck.
What hidden costs do traffic control fleets have?
The common ones are sign and device damage, vehicle damage at low speed in tight sites, tyre wear from kerbs and gravel, battery replacement on trailer-mounted plant, theft, downtime while vehicles are repaired or inspected, hire-ins to cover breakdowns, and the office time spent managing registrations, inspections and fines.
How do I include fleet costs in my traffic control rates?
Either bundle a standard ute and sign set into the controller rate, or charge vehicles and plant separately with their own minimums. Specialist plant such as TMAs, VMS boards and arrow boards is usually priced on its own line. Whichever you choose, base it on cost per job day at realistic utilisation.
