FMCSA Violations in Texas Truck Accident Claims
Commercial trucks aren't just big vehicles — they're heavily regulated ones. The Federal Motor Carrier Safety Administration (FMCSA) sets detailed rules on how many hours a driver can drive, how the truck must be maintained, how cargo must be secured, and how drivers are tested for drugs and alcohol. A regulatory violation may be relevant to a negligence theory depending on the specific rule, duty, facts, causation, admissible evidence and applicable Texas law. A violation does not automatically establish negligence or civil responsibility. This guide explains selected FMCSA rules and the types of records that may be relevant.

Hours-of-service violations and driver fatigue
Driver fatigue is one of the leading causes of fatal truck accidents. The FMCSA's hours-of-service rules limit how long a driver can be behind the wheel: generally, a driver may drive no more than 11 hours after 10 consecutive hours off duty, and may not drive beyond the 14th consecutive hour after coming on duty. Drivers must also take a 30-minute break after 8 hours of driving. When a carrier pressures a driver to exceed these limits — or a driver falsifies their logs to do it — fatigue sets in, reaction times slow, and the risk of a catastrophic crash soars. If ELD or other records show an hours-of-service issue, that evidence may be relevant to responsibility depending on causation, the complete evidence and applicable law.
Logbook falsification and ELD tampering
For decades, drivers kept paper logbooks of their hours — and falsifying them was common, earning the logs the nickname 'comic books.' Since 2017, the FMCSA has required most carriers to use electronic logging devices (ELDs) that automatically record driving time. But ELD tampering still happens: drivers unplug the device, use a separate vehicle, or manipulate the data. If an investigation identifies logbook falsification or ELD tampering, that conduct may be relevant depending on who engaged in it, the applicable rule, causation, admissibility and other evidence. It does not by itself establish carrier negligence or exemplary damages. Data availability and retention vary by system and record type.
Drug and alcohol testing violations
The FMCSA requires carriers to conduct pre-employment drug testing, random testing during employment, and post-accident testing after any crash involving a fatality or a citation for a moving violation. A driver who tested positive, refused a test, or whose carrier failed to conduct required testing is a serious safety risk. Post-accident drug and alcohol testing records may be relevant when the applicable testing rule, result, admissibility and causation connect to disputed issues. A positive result, testing failure or prior test history does not by itself establish negligence, negligent retention or civil responsibility.
Vehicle maintenance and inspection failures
The FMCSA requires carriers to systematically inspect, repair, and maintain their trucks, and to keep detailed inspection records. Brake defects, worn tires, faulty steering, and broken lights are common causes of truck crashes — and they're often the result of skipped or shoddy maintenance. A truck's inspection history, maintenance records, and the post-crash inspection report (often prepared by a qualified inspector after a serious crash) can reveal whether a mechanical failure caused the collision and whether the carrier knew or should have known about the defect. A carrier that put a known-defective truck on the road is negligent.
Cargo securement and load violations
The FMCSA's cargo securement rules require that cargo be loaded and secured so it doesn't shift, leak, or fall off the truck. Unbalanced or unsecured cargo can cause a jackknife, a rollover, or a loss of control — and when cargo spills onto the highway, it can cause secondary crashes. If the cargo loader (sometimes a separate company from the carrier) violated securement rules, both the loader and the carrier may be liable. The bill of lading, weight tickets, and post-crash cargo inspection can prove the violation.
How regulatory violations may relate to civil responsibility
A statutory or regulatory violation may have evidentiary or negligence-per-se implications only when the applicable Texas requirements are satisfied. The analysis can depend on the particular rule, the class and harm it was intended to address, causation, admissibility, and other case-specific facts. Exemplary damages require separate statutory standards and proof. How regulatory evidence may be presented in a Texas trucking case can also be affected by Texas House Bill 19's rules on regulatory evidence in bifurcated trials.
Records relevant to possible regulatory violations
Potentially relevant records may include ELD data, driver logs, maintenance records, testing records and available vehicle data. Retention requirements and technical availability vary by record type and system, so preservation needs should be evaluated from the specific circumstances. Retention periods and preservation duties vary by record and circumstances, so potentially relevant evidence should be identified promptly. Some evidence may have time-sensitive availability, while other records follow longer retention rules; the appropriate preservation analysis depends on the evidence involved. How strongly a violation affects your claim depends on the specific facts and evidence. For local resources, see our metro guides for Houston, Dallas–Fort Worth, and Austin.

Frequently asked questions
What is negligence per se in a Texas truck accident claim?
A regulatory violation may be relevant to negligence or negligence-per-se analysis, but its civil effect depends on the particular rule, causation, admissibility, the protected class and harm, defenses, and applicable Texas law.
What are the FMCSA hours-of-service rules?
Generally, a commercial driver may drive no more than 11 hours after 10 consecutive hours off duty, and may not drive beyond the 14th consecutive hour after coming on duty. Drivers must also take a 30-minute break after 8 hours of driving. Violations of these rules cause driver fatigue, a leading cause of fatal truck accidents.
How long must a trucking company keep its records?
Retention periods differ by record, system and applicable rule, and electronic data may be overwritten or become unavailable. A preservation notice may be appropriate in some matters, so potentially relevant evidence should be identified promptly.
Can FMCSA violations support punitive damages?
Yes. When violations show gross negligence or a conscious disregard for safety — such as knowingly forcing a driver to exceed hours-of-service limits, ignoring failed drug tests, or falsifying logs — they can support a claim for punitive (exemplary) damages, which are awarded on top of compensation for medical bills, lost wages, and pain and suffering.
