A breakdown is not one problem but a sequence of small ones, and stress reorders them: repairs get negotiated from a live lane; teardowns start before anyone has agreed to pay. Every expensive breakdown story we hear is an ordering mistake. If you are on the shoulder right now, do the first two moves and read the rest from the waiting room.

What to do when your car breaks down
Five moves, in order — the order is the part people get wrong with traffic going past. Works with or without coverage.
- Get safe and visibleHazards on before anything else, then work the car toward the shoulder while it still has momentum. Once stopped, stay out of live lanes: get out on the side away from traffic if you can, and wait well clear of the car — behind a barrier if there is one — rather than beside or behind it. If the car cannot be moved out of traffic, staying belted with the hazards on while you call for help often beats walking through live lanes.
- Get the car off the roadThis is a phone call, not a project. Roadside assistance and towing are included with US Auto Protect plans — the number is in your contract documents. No coverage? Check what you already hold before paying a stranger who found you first: auto insurers sell roadside as an add-on, motor clubs include it, and some automakers provide it through their app on newer cars. Have the car taken to a licensed repair shop you chose, not one chosen for you.
- Before anyone starts work, know your authorization stepIf you have a service contract, this is the move that decides everything downstream: the shop calls the claims line at 1-877-252-8036 for authorization before teardown, before parts are ordered, before a wrench is turned. Work started without authorization can be denied even when the failed part was plainly covered — and one sentence to the service writer prevents that. The full sequence is at how a claim actually works. No coverage? Keep the same discipline: nobody starts work until you have approved a written estimate.
- Get the diagnosis in writingGet a written diagnosis: the component that failed, why the shop believes it failed, and what they propose to do about it. With coverage, that is what authorization is decided against; without it, that is what a second opinion is made against. Either way, “it needs a lot of work” is not a diagnosis, and a shop that resists writing one down has told you something worth knowing.
- Decide with authorization, not under pressureThe emergency ended when the car left the road; what remains is a purchasing decision, and waiting rooms are engineered against good ones. With coverage, let the process work: authorization settles the covered repair and its cost before work begins, leaving you your deductible and anything your plan does not cover — both stated in your contract. Without coverage, take the written diagnosis and an hour, and call a second shop if the number feels wrong — a legitimate repair quote survives an hour.
What to keep in the car
The whole sequence goes better if five minutes of preparation happened months earlier. In the glovebox, coverage or not:
- Your service contract details and the claims line, on paper — the moment you need them is the moment your phone is about to die
- Whatever roadside number you actually hold: your plan's, your insurer's, or your motor club's
- A phone charger that works in this car, tested once
- A flashlight and something reflective to make a stopped car visible
- Registration and insurance card where a passenger could find them without you
Reading this with a healthy car and a service contract? How a claim actually works is worth five minutes now — the authorization step is the one part of a breakdown you can genuinely rehearse.
Rather not improvise on the shoulder?
A plan makes moves two and three somebody's job: the tow, the authorization, and paying the shop for covered repairs. Tell us the year and mileage — if the honest answer is to skip it, we'll say so.
