Key takeaways
- A traffic control team leader turns the traffic guidance scheme into a safe set-up, runs the crew and owns the records for the shift.
- The core skills are reading the plan against the real site, briefing, set-up and pack-down order, radio discipline, inspections and handling change.
- In NSW, implementing a traffic plan typically needs the Implement Traffic Control Plans qualification on top of the Traffic Controller card.
- The hardest part of the role is saying stop: to the client, to the crew and to yourself when the site does not match the plan.
- Good team leaders write things down as they happen, not at the end of the shift.
A traffic control team leader turns the traffic guidance scheme into a safe set-up on a real road, runs the crew through the shift and owns the records. The practical skills are reading the plan against the site, briefing, set-up and pack-down order, radio discipline, regular inspections, handling change and saying stop when something is wrong.
Most new team leaders are good controllers. That is necessary but not enough. The step up is from doing your position well to being responsible for every position, the client interface and the paperwork, often on the same morning a sign blows over and the excavator turns up early.
What changes when you step up
| As a controller | As a team leader |
|---|---|
| Know your position and escape route | Know every position and every escape route |
| Follow the briefing | Give the briefing |
| Report problems | Decide what happens next, or escalate |
| Follow the set-up order | Run the set-up order and check it |
| Hold your bat | Watch the whole site, including the work crew |
| Sign your timesheet | Complete inspections, docket and incident records |
| Talk to drivers | Talk to drivers, the client, the office and sometimes police or council |
In NSW, implementing a traffic control plan typically needs the Implement Traffic Control Plans qualification on top of the Traffic Controller card. Other states have their own frameworks. Check the qualification with SafeWork NSW or your regulator, and unit details on training.gov.au.
Skill 1: Reading the plan against the real site
Before the crew unloads anything, walk or drive the site with the plan in hand. Check:
- Does the road match? Lanes, parking, intersections, driveways, bus stops.
- Does the work match? Is the plant the plan assumed actually the plant on site?
- Can each sign go where the plan shows it, or is there a driveway, tree or bus stop in the way?
- Are there permanent signs that conflict with the temporary ones and need covering?
- Where will each controller stand, and where is their escape route?
The plan sets the distances, tapers and sign spacing for that speed and road, drawn from the state manual and AS 1742.3. Your job is to apply what the plan says, not to work out new numbers. If a symbol or note on the plan is unclear, ask the office before you set up, not after.
Skill 2: Running a briefing people actually remember
A good briefing is short, specific and in the same order every day. Brief your crew and the work crew together where possible. Our toolbox talk checklist has a full version; the core points are:
- The work today, the plant and the hours.
- The plan: closure type, positions, who stands where.
- Escape routes for each position.
- Radio channel, call signs and the stop call.
- How plant enters and leaves the work area, and who calls it.
- Pedestrians, cyclists, driveways and bus stops.
- Hazards: weather, heat, abuse, fatigue.
- What to do in an emergency, and where the first aid kit is.
- Questions, then sign-on to the SWMS.
Skill 3: Set-up and pack-down order
The set-up order protects the crew while they place devices. The general principle on most jobs:
- Park the vehicle where the plan allows, with warning lights on.
- Place advance warning signs first, starting with the one furthest from the work, working towards the site.
- Cover any conflicting permanent signs.
- Place the taper and delineation.
- Place the work area devices.
- Put controllers in position and do a radio check.
- Drive or walk the approach as a driver would see it, from each direction.
- Record the start-of-shift inspection, then tell the client the closure is ready.
Pack-down usually runs in reverse: work area, taper, advance signs, then uncover permanent signs and check the road is as you found it. Never leave a sign up that no longer applies.
Skill 4: Radio discipline
Good radio use is short and predictable. Use call signs, say who you are calling first and confirm every instruction. Standard calls a team leader sets in the briefing:
| Situation | Example call |
|---|---|
| Radio check | "TC 1 to TC 2, radio check." "TC 2, loud and clear." |
| Release traffic | "TC 1, releasing north, last car white ute." |
| Last car confirm | "TC 2, white ute through, holding." |
| Plant movement | "Team leader, excavator moving into lane, both ends hold." |
| Emergency stop | "All stop, all stop." Everyone holds traffic and acknowledges. |
If radios drop out, controllers hold traffic until contact is restored. Our guide to traffic control radio communication covers coverage and failure plans.
Worked example: a lane closure shift from start to finish
Example scenario: a team leader with two controllers is running a single-lane closure with stop/slow at each end on a two-lane collector road. A drainage crew is replacing a pit in the kerb lane. The shift is 6:30 am to about 3:00 pm.
6:30 am. The team leader walks the site with the plan. One advance sign location falls across a resident's driveway. The plan's tolerances allow it to move a short distance; the team leader moves it just past the driveway and notes the change and the reason.
6:45 am. Briefing with the controllers and the drainage foreman. The foreman says a vacuum truck will arrive at 9:00 am, which was not on the booking. The team leader checks the plan: the truck fits inside the work area but must reverse in across the open lane. They agree that the truck moves only when the team leader calls both ends to hold.
7:00 am. Set-up in order, radio check, drive-through from both directions. Start inspection recorded. Client told the site is ready.
9:10 am. The vacuum truck reverses in under the team leader's call. Both ends hold, the truck clears the lane, traffic resumes.
11:00 am. Wind picks up and the advance sign on the southern approach blows over. TC 2 calls it in. The team leader holds traffic at that end, re-stands the sign with extra ballast and records it in the inspection log.
12:30 pm. The foreman asks whether they can widen the work area to stack pipes in the lane. The team leader says no: that is a change to the closure the plan does not cover. The pipes are stacked inside the existing work area instead. If the foreman had insisted, the team leader would have rung the office for a plan revision.
2:45 pm. Work finishes. Pack-down in reverse order, permanent signs uncovered, end inspection recorded.
3:05 pm. The foreman signs the docket. The team leader adds notes on the moved sign, the vacuum truck and the wind.
Skill 5: Handling change and saying no
Change is normal. What matters is how you decide. Use this test:
- Within the plan: carry on, brief the crew, record it.
- Small adjustment within the plan's tolerances: make it, record it, tell the office.
- Outside the plan: stop that part of the work and escalate. Our guide on changing a TGS on site explains who can approve changes.
Saying no to a client is uncomfortable. Say it with a reason and a next step: "That would put the stack in the open lane. I can't do that under this plan. I'll ring the office now to see if we can get a revision."
Looking after the crew through the shift
A team leader is also responsible for the people holding the bats. Through the shift:
- Plan breaks and rotations at the briefing, so nobody stands on a hot, busy position for hours without relief. Cover each position before someone leaves it.
- Watch for heat and fatigue: slower reactions, sloppy signals, sitting down on position. Rotate the person or give them a break before it becomes an incident.
- Back people up when drivers are abusive. Go to the position, take over if needed, and record what happened.
- Keep an eye on the new starter. Give them the simpler position and check on them more often.
- Respect the company's fatigue limits when a client asks to keep going. An overrun that pushes the crew past the limit needs the office's decision, not a quick yes on site.
Dealing with the public and the client
Most of a team leader's conversations are with people who are not on the crew. Keep them short, calm and factual. Residents want to know when they can get out of their driveway; tell them honestly and help them through at the next safe opportunity. The client's foreman wants to start; tell them when the site will be ready. Police, council inspectors and the principal contractor's safety staff may ask to see the plan and the inspection record, so keep both where you can hand them over straight away.
Skill 6: Records that hold up
Write things down when they happen. At minimum, a team leader's record for the shift includes:
- ☐ Plan reference and version used.
- ☐ Start-of-shift inspection, inspections during the shift and end-of-shift inspection, with times.
- ☐ Any changes, with the reason and who approved them.
- ☐ Incidents, near misses and complaints.
- ☐ Crew names, start and finish times, and breaks.
- ☐ Equipment used.
- ☐ Docket signed by the client.
A good traffic control site diary makes this easy to do in a few minutes as you go.
Next steps
If you are aiming for team leader, ask to shadow one for a few shifts and practise the briefing and the site walk. If you run a crew, TrafWise puts pre-start checks, SWMS sign-on and dockets in the crew app so team leaders can record as they go.
Frequently asked questions
What does a traffic control team leader do?
A team leader checks the traffic guidance scheme against the site, briefs the crew and the work crew, sets up and packs down the signs and devices in the right order, assigns positions, runs radio communication, inspects the set-up during the shift, manages changes and incidents, and completes the dockets and inspection records.
What qualification do I need to be a traffic control team leader in NSW?
In NSW, setting out and implementing a traffic control plan typically requires the Implement Traffic Control Plans (ITCP) SafeWork NSW card in addition to the Traffic Controller card, plus a white card on construction sites. Requirements differ in other states. Check current rules with SafeWork NSW or your state regulator and an RTO.
How long before a traffic controller can become a team leader?
There is no fixed time. Most companies want controllers to have worked a wide range of set-ups, such as stop/slow, lane closures, pedestrian detours and night work, and to have shown good judgement before they put them in charge. Experience across different sites matters more than months on the job.
What should a team leader do if the site does not match the plan?
Do not improvise a different layout. Stop and contact the person or office responsible for the plan. Minor adjustments may be allowed within the plan's tolerances, but significant changes usually need a revised plan approved by a suitably qualified person. Record what you found, who you contacted and what was decided.
How do team leaders handle a client who wants to start before set-up is finished?
Explain calmly that work starts when the closure is complete and checked, then give a realistic time. Most clients accept a clear answer. If they insist, escalate to your office and record the conversation. Never let plant into the work area before the set-up is complete and inspected.
