Roadside Breakdown Playbook

You're on the shoulder. Here's the order to do things in, starting with not getting killed.

It's going to happen. Doesn't matter how good your maintenance is or how new the truck is. Something lets go, and now you're on the shoulder with traffic doing 75 four feet off your mirror.

The guys who handle it well aren't calmer by nature. They just have an order they follow. Here's one.

First: get somewhere survivable

The single most dangerous part of a breakdown is the location, not the failure.

If the truck still moves at all, keep moving to somewhere better. An exit ramp, a wide shoulder, a scale, a gas station, anywhere with distance from traffic. A quarter mile of limping on a bad tire is usually the right trade against sitting in a live lane. You'll know the exceptions — no brakes, no steering, fire, smoke.

If you have to stop where you are, get as far right as the shoulder allows and get straight. Wheels straight or angled away from traffic, not into it.

Lights on. Four-ways immediately. At night, everything you've got.

Second: mark yourself and get out of the danger zone

Put your triangles out. Do it the way you were taught and do it facing traffic, not with your back to it. This is the part people skip when they're frustrated, and it's the part that saves lives.

Then get out of the truck on the passenger side and get away from the traffic side. If you're on an interstate shoulder, stand off the shoulder, behind a barrier if there is one, uphill or up-embankment if you can. Do not stand between your truck and traffic. Do not stand in front of the truck. Do not crawl under it on the traffic side.

Vest on. Every time, day or night.

Third: figure out what you actually have

Now, from a safe spot, take two minutes and assess before you call anybody. What you can tell the dispatcher or the shop determines how fast the right help shows up and what it costs.

Sort it into one of these:

  • Won't start / won't build air / no power. Note whether it cranked, whether the dash lit, whether it died while driving or wouldn't restart after a stop.
  • Tire. Which position. Steer, drive, or trailer. Inside or outside dual. Whether there's damage to lines, skirts, or fenders from the casing.
  • Overheating or fluid loss. How much, what color, where it's coming from, whether the truck derated first.
  • Fault code / derate. What the dash says exactly. Photograph it.
  • Something mechanical let go. Noise, vibration, driveline, brakes dragging, smoke.

Don't diagnose past what you can see. Report what happened and what it did, the same way you would in the shop. The dispatcher relays it. If you guess wrong out loud, the wrong truck rolls.

Fourth: make the calls, in order

1. Your company or your dispatch. If you're a company driver, this is first, always. They have accounts, breakdown vendors, and rules about who's authorized to spend money. Rolling your own service without approval can cost you the reimbursement.

2. Your breakdown service or roadside program if you're an O/O. Have the number saved before you need it. Know your account number.

3. Law enforcement if you're in a hazardous spot, blocking a lane, or in bad weather. A cruiser with lights behind you is the best protection you can get on a shoulder, and they can get a wrecker rolling faster than you can.

When you call service, give them:

  • Exact location. Highway, direction, mile marker, nearest exit. Pull it off your GPS and read it out. "Just past the rest area" isn't a location.
  • Truck info. Year, make, engine, and the unit number.
  • The symptom, described plainly.
  • Whether you're loaded, what you're hauling, and if it's temperature sensitive or hazmat.
  • Whether you're in a safe spot or exposed.

Ask for an ETA, a callback number, and the vendor's name. Write it down with the time.

Fifth: protect the clock and the load

While you're waiting, do the paperwork side.

Log the breakdown properly. Note the time you went out of service. Know your options under the rules for adverse conditions and for getting to safe parking, and don't guess at it under stress — if your company has a safety line, use it.

Notify the receiver or have dispatch do it. A late load that came with a phone call three hours ahead is a different conversation than a load that just doesn't show.

Take photos. The truck, the failure, your triangles out, the location, the damage. If a casing took out a fender or a fairing, that's a claim. If a vendor damages something, you want the before shot.

Keep every receipt and every invoice. Note the vendor's arrival time and departure time yourself, because those numbers show up on bills and they aren't always right.

Sixth: what you should and shouldn't fix yourself

There's a line and it's worth knowing before you're standing in the dark deciding.

Reasonable to handle if you're able and it's safe: a blown fuse, a loose battery cable, a dragging mudflap, a glad hand seal, chaining a light back up, replacing a bulb, adding fluid you carry, resetting a trailer air line that's kinked.

Not on a shoulder, ever: anything requiring you to get under the truck on the traffic side, anything involving jacking on soft or slanted ground, tire work with traffic passing, anything hot, anything involving high pressure fuel, and anything where the truck could roll.

The mechanic mindset here is simple: on a shoulder you are not in a shop, you're in traffic. The math on "I can save $600" changes when the risk is getting hit.

Seventh: the wait

Bring the truck down to a stable state. Fuel and load secure, brakes set, wheels chocked if you have chocks and the ground calls for it.

Stay reachable and stay warm or cool. Know where your water is. If it's winter, that idle time and your fuel level matter, and if the truck won't idle, know what you've got for blankets before it gets dark.

Update dispatch when things change. Silence gets treated as "nothing's happening" and you'll get forgotten in the queue.

Eighth: after

When it's fixed, write the whole thing up while it's fresh. Symptom, conditions, what the road service did, and what's still not right. Roadside repairs are frequently temporary — a service truck's job is to make you movable, not to fix root cause. If you got a jump, a tire, or a bypass, that truck needs shop time soon.

Then look at what warned you. Most breakdowns had a signal. A slow leak, a light that came and went, a noise you'd been living with, a tire you meant to check. That's not to beat yourself up. It's to build the pattern, because that pattern is what keeps you off the shoulder next time.

You know how this job works. Sooner or later everybody sits on a shoulder. Handle it in order, get home, and get back out.
