What Is a DOT Out-of-Service Order?
Commercial trucks get inspected at roadside checkpoints, weigh stations, and carrier terminals across the country. When an inspector finds a defect serious enough to create an immediate danger, the inspection stops being routine. The inspector issues an out-of-service order, and the truck or the driver is done operating until the problem is fixed.
The authority for vehicle orders sits in 49 CFR 396.9. Authorized personnel must declare and mark out of service any motor vehicle “which by reason of its mechanical condition or loading would likely cause an accident or a breakdown.” The inspector affixes an “Out-of-Service Vehicle” sticker, and no motor carrier may require or permit anyone to operate the vehicle until the repairs are made. The regulation leaves no room for judgment calls by dispatch. The truck stays parked.
Drivers get sidelined the same way. Under 49 CFR 395.13, a driver who has exceeded federal driving-time limits is ordered out of service, and no carrier may require or permit that driver to operate a commercial motor vehicle until the driver can lawfully do so. Our page on hours-of-service violations covers how those driving-time limits work and why fatigued-driving evidence carries so much weight.
The pass-fail standard inspectors apply comes from the North American Standard Out-of-Service Criteria, published by the Commercial Vehicle Safety Alliance (CVSA). The criteria identify the critical violations that render a driver, vehicle, or cargo out of service until the defect is corrected, and CVSA updates them annually, effective April 1 of each year. An out-of-service order is a trained inspector working through a published national standard and concluding, in writing, that this specific truck or driver was too dangerous to continue.
The flip side of that coin helps carriers, which is exactly why the records carry weight. When a vehicle passes a full inspection with no critical violations, the inspector affixes a CVSA decal to the unit, a visible certification that it cleared the published criteria that day. Inspectors handed out 16,521 of those decals during the 2025 International Roadcheck alone. The system documents both outcomes. A clean fleet has the paper to show it, and a dirty fleet cannot hide from its own inspection file.
Common Out-of-Service Violations
Out-of-service violations fall into two broad buckets: defects on the vehicle and problems with the driver. Both end the trip on the spot, and both leave a record your legal team can use later.
Vehicle Violations
The most common vehicle OOS violations involve the systems that keep an 80,000-pound machine controllable:
- Brakes that are out of adjustment, leaking air, or carrying cracked drums
- Tires with worn tread, sidewall damage, or severe underinflation
- Inoperable headlamps, brake lights, and clearance lights
- Steering components with excessive play or visible wear
- Cargo that is overweight, unsecured, or improperly tied down
- Cracked frames and defective coupling devices between tractor and trailer
The enforcement data shows how dominant brake problems are. In the 2025 International Roadcheck results, brake systems were the most-cited vehicle out-of-service violation in North America at 24.4 percent, with tires second at 21.4 percent. Counting both brake categories CVSA tracks, brake-related defects accounted for 41.1 percent of all vehicle out-of-service violations. Lights came in at 12.8 percent and cargo securement at 11.4 percent.
Tire failures deserve their own mention because of how they end. CVSA’s 2025 data counted 2,899 tire-related out-of-service violations, covering flat tires, insufficient tread depth, severe cuts exposing the cord ply, improper repairs, and tires not rated for the load being carried. A tire in that condition can rupture at highway speed, and CVSA notes the results: loss of control, rollovers, and debris scattered across travel lanes. Each of those defects was visible to anyone who looked before the truck left the yard.
Driver Violations
Drivers are placed out of service for who they are on paper and what their logs show. In the same 2025 Roadcheck data, hours-of-service violations were the top driver out-of-service category at 32.4 percent, followed by driving without a required commercial driver’s license at 24.4 percent, no medical card at 14.9 percent, false logs at 10 percent, and a suspended license at 5.1 percent. Several of those categories point straight at the company that put the driver behind the wheel, which is why our driver qualification violations page treats hiring records as liability evidence.
False logs are the category that should worry every motorist. A falsified record of duty status conceals how long the driver has really been behind the wheel, which defeats the entire purpose of the fatigue rules. CVSA reported that FMCSA’s 2025 roadside inspection data logged 6,823 false record-of-duty-status violations nationwide through late August of that year. When a fatigued driver causes a collision and the logbook turns out to be fiction, the falsification itself becomes part of the case.
Inspections Pull Thousands of Trucks Off the Road
During CVSA’s 2025 International Roadcheck, inspectors conducted 56,178 inspections in 72 hours and placed 10,148 commercial vehicles and 3,342 drivers out of service. The vehicle out-of-service rate was 18.1 percent. Nearly one in five trucks inspected was deemed unsafe to keep driving that day.

“When you’re stressed and overwhelmed after a wreck, it makes such a difference to have a team that takes care of everything for you.”
– D. CRABTREEHow the FMCSA Tracks Repeat Violators
A single inspection tells you about one truck on one day. The federal government tracks the bigger picture through Compliance, Safety, Accountability (CSA), the FMCSA’s data-driven safety compliance and enforcement program. CSA has three core components: the Safety Measurement System, interventions, and a Safety Fitness Determination rating that helps the agency remove unfit carriers from the road.
The Safety Measurement System (SMS) pulls roadside inspection and crash data from the previous two years and organizes it into seven Behavior Analysis and Safety Improvement Categories, the BASICs: Unsafe Driving, Crash Indicator, Hours-of-Service Compliance, Vehicle Maintenance, Controlled Substances and Alcohol, Hazardous Materials Compliance, and Driver Fitness. FMCSA updates the system monthly, groups carriers with similar inspection histories, and assigns percentile rankings that decide which companies get prioritized for enforcement intervention.
Every out-of-service order a carrier receives feeds this system. A company whose trucks keep failing inspections builds a measurable, time-stamped record of its own maintenance and supervision failures, maintained by the federal agency that regulates it.
Carriers cannot claim they never saw the numbers. The same SMS page notes that complete results are available to carriers logged into their own safety profiles. A trucking company watches its own percentile rankings move month by month. When those rankings deteriorated for a year before the collision and the company changed nothing, that timeline becomes a story about choices, told entirely through federal data.
Much of that record is public. The FMCSA’s SAFER Company Snapshot is a free electronic record of a carrier’s identification, size, and safety record, including its safety rating, a roadside out-of-service inspection summary, and crash information. Anyone can search it by company name or USDOT number. When the snapshot shows a carrier with out-of-service rates well above the national figures, that carrier cannot credibly claim it had no idea its fleet was in poor condition.
OOS Violations as Evidence of Negligence
A Kentucky truck accident case turns on proof that the carrier or driver failed to use ordinary care. An out-of-service order hands the injured person a piece of evidence most cases never have: a government inspector’s written, contemporaneous determination that this truck or this driver was too dangerous to be on the road. There is no softer way for a defense lawyer to describe it to a jury.
The strongest version is a crash involving a truck or driver under an active out-of-service order. 49 CFR 396.9 prohibits a carrier from requiring or permitting anyone to operate a vehicle marked out of service until it is repaired. If the truck moved anyway, someone at the company made that decision after being told, in writing, not to.
When a Carrier Ignores an OOS Order
Federal law attaches real penalties to that decision. Under the civil penalty schedule in Appendix B to 49 CFR Part 386, a CDL holder convicted of violating an out-of-service order faces a civil penalty of at least $3,961 for a first conviction and at least $7,924 for any conviction after that. An employer who knowingly allows, requires, permits, or authorizes a driver to operate during an out-of-service period faces a penalty between $7,155 and $39,615.
For the injured person, the violation can support more than an ordinary negligence claim. Kentucky’s punitive damages statute, KRS 411.184, permits punitive damages where clear and convincing evidence shows the defendant acted with oppression, fraud, or malice. The statute defines malice to include conduct carried out with flagrant indifference to the plaintiff’s rights and a subjective awareness that it will result in death or bodily harm. Dispatching a truck that a federal inspector ordered off the road fits that argument about as cleanly as any fact pattern in trucking litigation. Whether punitive damages apply is fact-specific to each case, and we develop that record from day one.
Even without an active order at the moment of the collision, an out-of-service history still works for you. A carrier that racked up repeated vehicle OOS violations was on notice that its maintenance program was failing the systematic inspection, repair, and maintenance duty imposed by 49 CFR 396.3. When a poorly maintained truck then injures someone, the inspection history shows a pattern, and patterns are what move juries and adjusters.
DVIRs Are Often the Smoking Gun
Under 49 CFR 396.11, a driver must prepare a written inspection report at the end of each day’s work, and the carrier must certify that any listed defect was repaired, or that repair was unnecessary, before the vehicle runs again. A defect noted on a DVIR with no repair certification behind it is the carrier documenting its own knowledge of the problem.
Records That Prove OOS Violations
Out-of-service evidence lives in specific documents, each held by someone with no interest in volunteering it. These are the sources we go after:
- The SAFER Company Snapshot, the free public record of the carrier’s inspection summary, out-of-service data, and crash history
- Roadside inspection reports, the documents inspectors complete at each stop listing every violation found and every out-of-service determination made
- Driver vehicle inspection reports required by 49 CFR 396.11, with the carrier’s repair certifications
- Carrier maintenance files required by 49 CFR 396.3, which show what the company knew about each vehicle and when
The retention windows are short. Under 49 CFR 396.11, a carrier only has to keep DVIRs and repair certifications for three months. Under 49 CFR 396.3, maintenance records must be retained for one year where the vehicle is housed and six months after the vehicle leaves the carrier’s control. A family that waits to act can lose the strongest documents in the case to a lawful records purge.
That is why preservation comes first. A litigation hold letter goes to the carrier and its insurer immediately, putting them on written notice to keep inspection reports, DVIRs, maintenance files, and electronic logging data intact. From there, the full paper trail comes out through subpoenas and document requests, a process we walk through on our truck accident discovery page. The on-scene side of the investigation, from vehicle inspections to camera footage, is covered in our guide to truck crash investigations.
How We Use OOS Records
Our dedicated trucking team treats every serious truck collision as a case headed to litigation, because the carrier’s insurer is already treating it that way. Within hours of being retained, we pull the carrier’s public safety profile, send preservation demands, and start matching the public out-of-service record against the documents only discovery can reach.
The cross-referencing is where cases get won. A brake violation on a roadside inspection report gets lined up against the DVIRs for that tractor, the maintenance file for that unit, and the repair invoices the carrier produces. When the dates show a defect that was reported, never certified as repaired, and still present when the truck hit you, the negligence story writes itself in the carrier’s own handwriting. Where the driver’s logs are the problem, the same approach applies to hours-of-service records. The full scope of what we handle in these cases lives on our truck accident practice page.
The fee structure stays simple while all of that work gets done. You pay $0 out-of-pocket forever, with no increased charges if the case goes to litigation or trial. If a trucking company’s insurer is already calling you, get a free case review before you give any statement.
Frequently Asked Questions About Out-of-Service Violations
What does out of service mean for a commercial truck?
It means an inspector determined the truck or driver could not continue operating. Under 49 CFR 396.9, a vehicle whose mechanical condition or loading would likely cause an accident or breakdown is declared and marked out of service, and no carrier may permit it to run until repairs are made.
Can an out-of-service violation be used as evidence in a truck accident case?
Yes. An out-of-service order is a government inspector’s written determination, made under the CVSA out-of-service criteria, that the truck or driver was unsafe. That record supports a negligence claim, and operating in violation of the order strengthens the case considerably.
How do I find a trucking company’s out-of-service history?
The FMCSA’s SAFER Company Snapshot is a free public record searchable by company name or USDOT number. It includes the carrier’s roadside out-of-service inspection summary, safety rating, and crash information. Complete inspection and maintenance records come later through discovery in litigation.
Can I seek punitive damages if a carrier ignored an out-of-service order?
Potentially. Under KRS 411.184, punitive damages require clear and convincing evidence of oppression, fraud, or malice, and malice includes flagrant indifference with awareness that the conduct will cause death or bodily harm. Running a truck the government ordered parked can support that argument. Every case is fact-specific.
What records show out-of-service violations?
The SAFER Company Snapshot, roadside inspection reports, driver vehicle inspection reports required by 49 CFR 396.11, and carrier maintenance files required by 49 CFR 396.3. Retention windows are short, so a preservation letter should go out immediately after a collision.
How often are trucks actually placed out of service?
Often. During CVSA’s 2025 International Roadcheck, inspectors conducted 56,178 inspections over three days and placed 10,148 vehicles and 3,342 drivers out of service. The vehicle out-of-service rate was 18.1 percent, nearly one in five trucks inspected, with brake systems the most-cited vehicle defect.
