What Role Do Maintenance Logs Play in Truck Accident Liability?

Published on Nov 10, 2026 at 8:38 am in Truck Accidents.

You were stopped at a red light on Route 251 in Peru, listening to a podcast as you waited for green. That’s when a semi crashed through the back of your car and changed everything in your life. The driver told the investigating police officer that his brakes had felt soft for the past few miles, and they just didn’t engage before the crash.

Somewhere there’s a record of when that truck’s brakes were last inspected, what the driver last wrote up, and most crucially, whether anybody fixed it.

Those truck maintenance logs can show whether your crash was bad luck or a problem the company already knew about, which sits at the center of trucking company liability in Illinois. They can also be thrown out legally while you’re still in physical therapy. If you’re wondering what that truck’s paperwork can prove and how to keep it around, start with what the law makes a carrier write down.

What Federal Law Makes a Trucking Company Write Down

The company running the truck that slammed into you has to systematically inspect, repair, and maintain it, and the FMCSA maintenance requirements spell out what the paperwork has to show. That applies to any truck or trailer it has controlled for 30 straight days or more. Its file on that truck should identify it, show which inspections and maintenance jobs were due and when, and log the date and nature of every repair. Those commercial vehicle inspection records have to stay where the truck is housed or maintained for a year, plus six months after it leaves the company’s control.

If the driver who had that truck the day before noticed the brakes were off, federal rules required a written driver-vehicle inspection report. The form follows a federal checklist, from the brakes and steering to the tires and mirrors. A driver who finds nothing wrong doesn’t have to file one, so a report that exists is one that found something, and the company only has to keep it for three months.

The company had to fix the problem or certify that it didn’t need fixing before the truck went back into service. The next driver was supposed to read the report and sign it. The truck’s annual inspection report has to stay on file for 14 months, and federal motor carrier safety regulations make it a violation for anyone to make a fraudulent or intentionally false entry on any of these records.

When the Same Repair Keeps Getting Pushed Back

Suppose the schedule for that truck showed that:

  • A brake inspection was due in March
  • The next brake entry was an adjustment in July
  • Two driver reports in between said the brakes felt soft.

Any one of those entries could have an innocent explanation. Put together, they show written proof that a truck kept running with a known brake problem. That turns a crash into a serious question about how the company operates.

None of that makes a villain, since a dispatcher with loads to cover and a shop with a two-week backlog can push a repair back one more trip while the log records every choice. In a federal study of large-truck crashes, brake problems turned up in about 29 percent of the trucks involved. Worn tires and loose steering parts leave the same kind of data trail, which makes the logs a strong piece of mechanical failure evidence before a mechanic ever crawls under the truck.

The Paper Trail Beyond the Carrier’s Files

The file the company keeps on that truck is only part of the paper trail, because plenty of carriers send their trucks to outside shops. Those truck repair invoices show what the mechanic actually did and which parts went on, and some of them note a repair the shop recommended that nobody approved. Parts orders count, too. If the company’s log says new brake shoes went on in May, but there’s no invoice or parts order for them anywhere, that missing paper is itself evidence.

Then there’s the truck itself. A forensic mechanic can measure how far the brake pushrods travel and how worn the linings are, then compare that to a log claiming the brakes were adjusted the week before your crash.

Spoliation of Evidence and Why the First Weeks Count

Once those retention periods run out, the company can throw the records away without breaking any federal rule, and the driver reports from before your crash are the first to go.

Illinois doesn’t impose a general duty to hang on to evidence. For the company that ran that truck, a duty can come from a statute, an agreement, or special circumstances, but only if a reasonable carrier in its position would have seen the records as material to a likely lawsuit.

A preservation letter sent in the first days after your crash tells the carrier in writing which records and evidence to keep, including:

  • The driver reports
  • The shop invoices
  • The truck itself

This letter makes it much harder for the company to argue later that nobody saw a lawsuit coming. If the records still disappear, an Illinois jury can be told it may infer that the missing evidence would have hurt the company that controlled it, unless that company had a reasonable excuse.

Talk to Our Firm While the Records Still Exist

The brakes on that truck had a history long before it crashed into you. It’s highly likely the trucking company’s own records are where that history was written down. Schweickert Ganassin Krzak Rundio, LLP has served North Central Illinois for more than 40 years, and we’ll come to your home or your hospital room to talk. Your first consultation is free.

If a semi hit you, reach out to our firm, and bring whatever you have from the crash, even if it’s just a photo of the truck’s door.
