If you run your own truck on broker freight and you’re the one who answers the phone when something goes wrong, sooner or later you’re going to be sitting on a dark shoulder with the engine dead, a load due in the morning, a shop you’ve never heard of quoting you a number you can’t check, and nobody but you to make every call, which is exactly why the time to plan for that night is right now, on a quiet afternoon, while the truck is running fine.

A breakdown playbook is just a handful of decisions you make ahead of time and write down where you can grab them. You’re not going to think clearly at 2 a.m. with trucks blowing past you. Nobody does. But if the shop numbers, the warranty hotline, your spending limit and the words you’ll say to the broker are already on one page, you just read and dial. That’s the difference between losing half a day and losing three.

Know What a Breakdown Really Costs You

Start with how often this happens, because it’s more than most new owners figure. In the TMC and FleetNet America roadside benchmarking data, truckload fleets averaged a little over 23,000 miles between unscheduled roadside repairs. That report is from 2020, so treat it as a rough yardstick, but the math still tells you something. If you put 100,000 miles a year on your truck, plan on something like four roadside events a year. Not maybe. Plan on it.

That same report put the average mechanical roadside repair at $542, and that’s before tires and before any tow. Costs haven’t gone down since. ATRI’s latest operational cost study found repair and maintenance cost per mile climbed about 8.6 percent in 2025, tires rose too, and total marginal cost hit a record of about $2.33 a mile. The TMC data also showed five systems, tires, brakes, the engine, lights and exhaust, made up about 72 percent of roadside repairs. That’s handy, because it tells you what parts and which kinds of shops your plan has to cover.

Here’s the part that hurts more than the repair bill, though. Every day the truck sits, you don’t earn. A cheap repair that takes three days to get scheduled isn’t cheap. So the whole point of a playbook is to cut the hours between when the truck stops and when it rolls again.

Worked Example, What Two Lost Days Cost

Let’s put real numbers on it. Say you’re running a dry van and your loads average $2.40 a mile all-in, meaning that rate includes the fuel money whether the broker pays it as one number or as linehaul plus a separate fuel surcharge. You usually cover about 550 loaded miles a day. Diesel runs you roughly 60 cents a mile.

Now the truck goes down on a Tuesday night and doesn’t roll until Thursday night. That’s two full days lost, or about 1,100 miles you didn’t run. At $2.40 a mile, that’s $2,640 in gross revenue gone. But you didn’t burn fuel on those miles either, so take the fuel back out: 1,100 miles times 60 cents is $660. What you really lost is about $1,980, and that’s before the repair, the tow, a motel room, and whatever the broker does about the late load.

This is why you always strip fuel out when you figure downtime. If you only look at the all-in rate, you’ll overstate the loss and maybe make a panicky call, like paying a premium for a part you didn’t need overnight. If you look at linehaul only and forget the fuel money is part of your pay, you’ll understate it. Use the all-in rate, then subtract what fuel would have cost you.

Now run the same breakdown with a plan. You already know a mobile mechanic on that stretch of interstate, you called the warranty line before anyone touched the truck, and you’d set a spending limit so you weren’t stuck waiting for a callback to approve the work. The truck rolls Wednesday afternoon. You lost maybe half a day instead of two, which is roughly $1,500 you kept. Four breakdowns a year, and the plan pays you back several times over.

Build Your One-Page Breakdown Card

Everything goes on one page per truck. Keep a printed copy in the glovebox, a photo of it in your phone, and if you’ve got a driver, a photo in theirs too. Here’s what goes on it, in this order.

First, the truck. VIN, plate, unit number, engine make and serial number, transmission make. A shop will ask for these on the first call, and reading them off a card is a lot faster than climbing out to look.

Second, coverage. Every warranty with its phone number, contract number and end date. Your insurance roadside or towing coverage, if you have it, and its number. Read your warranty contract now and write down whether it wants a call before any repair starts. Some contracts do, and if you skip that call you can lose the claim.

Third, money. Write down the card you’ll use for a roadside repair and make sure it has enough room on it. Then write your spending limits. For example: up to $300, the driver can approve it alone, things like a tire repair or a light. Over $300, call the owner. Over $1,500, nothing happens until there’s a written estimate and someone has checked the warranty. Pick numbers that fit your bank account, but pick them now.

Fourth, shops. For each lane you run every week, list three: a dealer for your engine brand, an independent truck shop, and a mobile repair outfit that answers at night. Don’t trust a directory listing. Call each one in the daytime and ask a few simple questions.

That’s ten minutes per lane. Write the answers next to each shop. If nobody answers in the daytime, they sure won’t answer at midnight, so cross them off.

What to Say When the Truck Stops

Safety comes before any phone call. Federal rules say you turn your flashers on right away when you stop on the road or shoulder, and get your warning triangles out as soon as you can, no later than 10 minutes after stopping. On a divided highway the triangles go roughly 10 feet, 100 feet and 200 feet behind the truck, and the rule has extra placement steps for hills and curves. You can read the whole thing in 49 CFR 392.22. Once the triangles are out and you’re clear of traffic, then you call.

If you’ve got a driver, teach them to report the same four things every time: where they are, what the truck is doing, what load is on, and how much time is left on their clock. Practice it once at the kitchen table so it’s automatic.

Then you call the shop, and you set the terms in the first minute. A shop that’s never heard of you knows you don’t have a lot of choices out there, so make it clear you want everything in writing.

Last call, the broker. Call before they’d notice anything’s wrong, give them a real new time, and tell them when you’ll call back. Brokers deal with breakdowns every day. What gets you cut off is silence, not the breakdown itself. If the load can’t make it at all, ask whether they want to recover it with another truck so you don’t end up eating a bigger mess later.

Close Out the Breakdown Within Two Days

When the truck rolls again, take care of four things within 48 hours while the paperwork is still in your hand. Write down the whole cost, repair, tow and the revenue you lost, in your maintenance records so you know your real cost per mile. File the warranty claim while you still have the old part and the shop’s notes. Look at what failed and ask whether your PM schedule should have caught it. And grade the shop on your card. Would you call them again at 2 a.m.? If not, cross them off and find another.

Questions Carriers Ask

Do I really have to put triangles out if I’ll only be stopped a few minutes? If you’re stopped on the traveled part of the road or the shoulder, yes. The rule gives you up to 10 minutes to get them out, and the flashers have to be on until they’re placed. There are a few exceptions in town where street lights make you visible, but on the interstate at night, get them out.

Should I call the warranty company or the shop first? Check your contract today so you don’t have to guess. If it says to call before repairs start, that call comes first, then the shop. Either way, don’t let anyone start work past a diagnostic until you know what’s covered.

How much should I keep set aside for breakdowns? Take the number of roadside events you expect in a year, figure about four for 100,000 miles, and multiply by what a repair, a tow and a couple of lost days cost you. With the worked example above, that adds up fast, which is why a lot of owners set aside a few cents from every mile into a separate repair account.

I’m a company driver. Does any of this apply to me? Yes. Ask your carrier for their breakdown steps and the numbers you’re supposed to call, and build a card for yourself anyway. When you get your own authority, you’ll already have the habit, and you’ll know what it costs when a carrier doesn’t have a plan.
