Vehicle Breakdown Checklist
A breakdown is the one fleet event where the first two minutes matter more than everything after them. This checklist is ordered by what will hurt you soonest: people first, then the scene, then the report, then the load, then the vehicle. Read it before you need it, because nobody reads a checklist while standing on a hard shoulder.
The call comes in as 'it's stopped'. That is all anybody knows for the next twenty minutes, while the office rings round trying to establish where the vehicle is, what is wrong with it, whether the driver is safe, whether the load is time-critical, and which recovery contract covers this vehicle in this county. Meanwhile the driver is standing next to a live carriageway with a phone and no instructions.
The cost of a breakdown is set mostly during those twenty minutes. The mechanical fault costs what it costs. The delay, the second recovery vehicle sent because the first one could not lift it, the load that needed a transfer nobody arranged until four o'clock: those are all information problems, and they are solvable in advance.
So this checklist has two audiences. The first sections are for the driver at the roadside and should be in the cab. The last two are for whoever picks up the phone, and should be on the wall behind them. Both need to exist before the breakdown, because a breakdown is not the moment to design a process.
40 checks across 6 sections
First — make it safe
- Get the vehicle as far off the live carriageway as it will go while it still has momentum. A vehicle that dies at fifty has more options than one that dies at five.
- Put the hazards on immediately, before anything else, including before you have decided what is wrong.
- Decide whether to stay in the cab or get out, and get it right. On a motorway hard shoulder, out and behind the barrier; on a quiet road at night, often safer inside with lights on.
- Put on high-visibility clothing before you open the door, not after you are standing in the road.
- Leave by the passenger side if there is any traffic at all.
- Place the warning triangle only where it is safe and lawful to do so. On a high-speed road, walking back with a triangle can be the most dangerous thing you do all year.
- Get any passengers out and behind a barrier, and keep them there rather than letting them wander back to the vehicle for a jacket.
- Do not attempt a roadside repair on a live carriageway, including a wheel change, whatever your experience is.
Then — report it properly
- Report your exact location before you report the fault. A marker post, a junction number, a kilometre marker or a GPS coordinate off your phone beats 'on the A road past the roundabout'.
- State whether you are safe and whether you are off the carriageway, because that determines who else gets called and how fast.
- Describe what happened rather than what you think broke: the noise, the warning lamp, whether it lost power gradually or stopped dead, whether it restarts.
- Say whether the vehicle is drivable, steerable, and whether it can be towed on its own wheels, since that decides which recovery vehicle is sent.
- State the load: what it is, how heavy, whether it is temperature-controlled, hazardous or time-critical.
- Give the vehicle's height, weight and dimensions if recovery will need them, and know where those numbers are.
- Say how many hours you have left, because a recovery that finishes after your hours run out creates a second problem nobody has planned for.
- Take photographs of the position and the fault while it is light, if it is safe to do so.
While waiting
- Stay where you told them you would be, and tell them if that changes.
- Keep the phone charged and answer withheld numbers, because the recovery driver will call from one.
- Do not accept help from anyone who arrives uninvited offering recovery, and confirm any recovery driver is the one your fleet dispatched.
- Note the time of every call and who you spoke to, because the timeline is what the insurer and the customer will both ask for.
- Keep the load secured and the vehicle locked if you are away from it.
- Do not let anyone unload or move the vehicle without an instruction from your own operation.
Protecting the load
- Tell the office immediately if the load is temperature-controlled and the unit has stopped, because that clock started before the phone rang.
- Establish who owns the decision to transfer the load, and get that decision made early rather than after recovery arrives and asks.
- Check the load restraint before any recovery lift, because a load restrained for driving is not necessarily restrained for a suspended tow.
- Photograph the load and its restraint before anyone touches it if a transfer is likely.
- Follow the specific procedure for hazardous goods rather than improvising, and say on the first call that the load is hazardous.
- Record who took custody of the load if it leaves on another vehicle, with a signature and a time.
Recovery and the driver
- Confirm which recovery contract covers this vehicle before calling, because the wrong call costs an hour and sometimes an invoice.
- Give the recovery operator the gross weight, the height and whether the vehicle can roll, on the first call rather than when they arrive with the wrong unit.
- Decide the destination before recovery arrives — roadside fix, nearest approved workshop, or home depot — because a vehicle recovered to the wrong place gets recovered twice.
- Arrange the driver's onward transport or rest as a separate task with its own owner, since it is the thing most often forgotten.
- Get the recovery paperwork signed and photographed at the scene, including the vehicle's condition on loading.
- Notify the customer with a real estimate rather than an optimistic one, as soon as you have anything worth telling them.
After the vehicle is back
- Record the root cause, not the symptom. 'Overheated' closes the job; 'radiator fan clutch failed, no fan on the last two services' prevents the next one.
- Check whether this fault appeared on any recent inspection sheet or defect report and was deferred or closed without action.
- Check whether a warning was available in the vehicle's data — a fault code, a temperature trend, a consumption drift — and whether anyone was watching for it.
- Book the same check across sister vehicles of the same age and duty if the cause is systemic rather than random.
- Record the true cost including recovery, the transferred load, the driver's lost hours and the customer credit, not just the parts and labour.
- Debrief the driver on what the process felt like from the roadside. That is the only way to find out that nobody answered the phone for forty minutes.
How to use this checklist
- Put the first two sections in the cab, laminated, in a place the driver can find in the dark without looking for it. A breakdown procedure stored on the intranet does not exist.
- Fill in your own numbers before you print it: recovery contract, out-of-hours contact, the escalation for hazardous or temperature-controlled loads. A generic checklist with no phone numbers on it is a leaflet.
- Rehearse the report. Ask a driver to describe their current location to you precisely, right now, over the phone. Most cannot, and finding that out today is much cheaper than finding it out on a hard shoulder.
- Run the last section on every breakdown, including the trivial ones. The breakdown that cost you forty minutes this month is usually the same fault that will cost you a day in the winter.
Frequently asked questions
Get the vehicle as far off the road as its remaining momentum allows, then hazards on, then decide whether to stay in the cab or leave it. Everything else — the fault, the load, the customer, the phone call — waits. The most common serious injury in a breakdown is not caused by the mechanical failure. It is caused by a person standing in a live traffic lane next to their vehicle trying to work out what went wrong.
On a quiet road, fully off the carriageway, in daylight, for something genuinely simple and within their competence: sometimes, if your policy says so and the vehicle carries the kit. On a motorway or any high-speed road, no, and this includes changing a wheel. Fleets that permit roadside repair should be explicit about exactly which repairs and exactly which conditions, because a driver making that judgement under pressure at the roadside will make it in favour of getting moving.
Almost all of that delay is information, not distance. The wrong recovery unit gets sent because nobody said the vehicle could not roll. The right one gets sent late because the location was described rather than given. Fix the report and you fix most of the delay: exact position, whether it is drivable, gross weight, height, and the load. A vehicle that reports its own position removes the largest single source of confusion before the call even starts.
Some of them, sometimes, and we are not going to claim more than that. A coolant temperature trend, a repeating fault code, a battery voltage sagging further each cold start and a consumption drift against a vehicle's own baseline are all real signals that precede real failures, and a fleet watching for them will catch a proportion of what would otherwise be roadside events. A snapped belt, a road hazard and a bearing that lets go without warning are not predictable by anyone. Prediction narrows the odds; it does not remove the need for this checklist.
The cause rather than the symptom, the full cost rather than the repair invoice, and the timeline. The cause is what stops it recurring on the other eleven vehicles of the same age. The full cost — recovery, load transfer, driver hours, the credit you gave the customer — is what tells you honestly whether your preventive maintenance is underfunded. The timeline is what tells you whether your own response worked, which is the one thing nobody thinks to write down and the only part you fully control.
