Key FMCSA Regulations in Crash Cases

The Federal Motor Carrier Safety Regulations (49 C.F.R. Parts 350-399) cover:

  • Part 382: Drug and alcohol testing requirements.
  • Part 383: Commercial driver's license standards and requirements.
  • Part 391: Driver qualifications — hiring, screening, medical certification, and road testing.
  • Part 392: Driving of commercial motor vehicles — distraction, fatigue, and safe operation rules.
  • Part 393: Parts and accessories — equipment standards for brakes, tires, lighting, and safety devices.
  • Part 395: Hours of service — driving and rest time limits.
  • Part 396: Inspection, repair, and maintenance requirements.

02

How FMCSA Violations Support Negligence Proof

FMCSA violations can be important evidence in trucking litigation because:

  • Safety-rule evidence: In Oklahoma, violation of a safety regulation may support a negligence theory depending on the rule, causation, and facts.
  • Carrier knowledge: Carriers are required to know and comply with FMCSRs, so compliance records can matter.
  • Pattern evidence: A carrier's history of FMCSA violations — documented in FMCSA inspection and compliance records — may help evaluate safety practices.
  • Punitive-damages review: Willful or reckless violations of federal safety regulations may require punitive-damages analysis.

03

How We Obtain FMCSA Records

  • FMCSA SAFER System: Public database containing carrier registration, safety ratings, and inspection summaries.
  • SMS Data: Safety Measurement System data showing the carrier's scores in seven Behavior Analysis and Safety Improvement Categories (BASICs).
  • Inspection Reports: Detailed reports from roadside inspections documenting specific violations found on the carrier's vehicles and drivers.
  • Compliance Reviews: FMCSA or state-level compliance review reports documenting systemic violations at the carrier level.
Carrier RecordsCarrier safety records and inspection reports can be reviewed early. FMCSA databases may help identify regulatory issues and guide the next records requests.

Common Questions

Does an FMCSA violation automatically prove the carrier was negligent?

Not automatically. In Oklahoma, a safety-rule violation may support a negligence theory, but the plaintiff still must prove the violation, causation, damages, and how the rule applies to the facts.
