Truck Talk: Truck Inspections

Watch this Truck Talk segment on YouTube

Commercial trucks operating on Kentucky highways are subject to mandatory inspections under federal and state law. These inspections exist because a mechanical failure on an 80,000-pound vehicle does not just end badly for the driver. It ends badly for everyone nearby. When carriers skip required checks or return defective vehicles to service, the inspections that are eventually performed by roadside enforcement become the record of what was ignored.

What Federal Law Requires

Under 49 CFR Part 396, carriers must systematically inspect, repair, and maintain every commercial motor vehicle they operate. Drivers are required to complete a pre-trip inspection before each trip and a Driver Vehicle Inspection Report (DVIR) at the end of each day. If a defect is found, it must be repaired before the vehicle goes back out. The DVIR becomes a legal record. When a carrier ignores a defect noted in a driver’s own report and the vehicle subsequently causes a crash, that document is powerful evidence of corporate indifference to road safety.

The Most Common Violations Found in Roadside Inspections

Roadside inspections conducted under the Commercial Vehicle Safety Alliance’s North American Standard reveal consistent patterns of what gets ignored. According to FMCSA enforcement data, the most common out-of-service violations issued during the 2023 fiscal year included: When inspectors find logbook irregularities, the carrier may face significant DOT fines for hours-of-service violations.

• Flat tires or audible air leaks: nearly 99,000 out-of-service orders
• Brakes with 20 percent or more defective: nearly 50,000 orders
• Inoperative turn signals: over 43,000 orders
• No or improper emergency braking systems: nearly 28,000 orders
• Inoperative brake lamps: nearly 23,000 orders

An out-of-service order means the vehicle or driver cannot move until the violation is corrected. These are not minor paperwork issues. They are vehicles that inspectors determined were not safe to operate on public roads at the moment of inspection.

Kentucky Inspection Enforcement

Kentucky State Police Commercial Vehicle Enforcement conducts roadside inspections at fixed weigh stations and through mobile enforcement on I-64, I-65, I-75, and other major routes. The Kentucky Transportation Cabinet also conducts periodic audits of carrier facilities. The results of every roadside inspection are reported to the FMCSA and become part of the carrier’s safety measurement score. A carrier with a pattern of brake, tire, and lighting violations across multiple inspections is accumulating a public record of maintenance failure that is relevant in any crash case involving one of their trucks.

Annual Inspection Requirements

In addition to daily driver inspections, federal regulations at 49 CFR Part 396.17 require every commercial vehicle to receive a formal annual inspection by a qualified inspector. The inspection must cover all major systems including brakes, steering, suspension, tires, lights, and coupling devices. A copy of the inspection report must be kept on the vehicle or accessible electronically. When a truck involved in a crash cannot produce a valid annual inspection certificate, that gap is immediately significant. Attorney Jon Hollan has noted that the annual inspection record, or its absence, is often the starting point for tracing how long a mechanical problem had been developing before it caused a crash.

How Inspection Records Factor into a Crash Case

When a crash is caused by or contributed to by a mechanical defect, the inspection history for that specific vehicle can show exactly how long the problem existed and who had the responsibility to fix it. Maintenance logs showing repeated entries for the same issue, DVIRs where a driver reported a defect that was marked as corrected but clearly was not, and roadside inspection records showing prior violations create a timeline of institutional neglect. These records are generally subject to a one-year retention requirement under 49 CFR Part 396, making prompt evidence preservation essential. See our Truck Talk on investigations for more on how this evidence is secured.

How Inspection Records Tie Into Insurance and Liability

A carrier’s inspection history is not just relevant to the individual crash case. It can also affect how aggressively the carrier’s insurer is willing to settle. An insurer reviewing a file where the truck had multiple prior out-of-service orders for the same type of defect that caused the crash knows that a jury trial is likely to be damaging. Systemic maintenance failures documented through inspection records shift the narrative from a single driver mistake to a pattern of institutional neglect, which is a far more powerful case for the injured party.

Kentucky motor carriers are subject to both federal FMCSA oversight and Kentucky State Police Commercial Vehicle Enforcement. The combined inspection programs mean that carriers operating the I-64, I-65, and I-75 corridors regularly face scrutiny. A carrier with a pattern of violations visible in public FMCSA records was on notice that its maintenance practices were deficient long before a specific crash occurred. That notice is relevant to whether the crash was the result of ordinary negligence or the kind of deliberate disregard for safety that supports a punitive damages claim under KRS 411.186.
