FMCSA Violations in Truck Accident Litigation: When Regulatory Compliance Becomes a Causation Question

Once a truck accident occurs, investigators immediately begin examining trucking data to determine whether the company complied with the Federal Motor Carrier Safety Regulations (FMCSRs). Driver qualification files are requested. Hours-of-service logs are scrutinized. Yet, that is only the beginning of the analysis. A trucking company may accrue a number of FMCSA violations without causing a collision.

Conversely, a single regulatory failure may explain why a crash became inevitable. At this juncture, an important question is raised: Did the violation create the conditions that caused the collision? Plaintiffs will seek to demonstrate that compliance with FMCSRs would have prevented the accident, while the defense attempts to separate the regulatory violation from the mechanics of the collision.

Why Does the Regulation Violation Matter?

Federal regulations establish minimum safety standards for commercial motor carriers but are not guarantees that every violation produces an accident. For instance, investigators may discover that a truck driver exceeded the maximum hours permitted under 49 C.F.R. Part 395. Standing alone, that proves only that the driver violated the hours-of-service regulations. It does not, however, establish that fatigue delayed braking, impaired judgment, or contributed to the collision.

This principle may be applied throughout the FMCSRs. Under Part 396, a truck may be overdue on maintenance but not experience a mechanical failure. Cargo may technically violate securement requirements under Part 393 without shifting during transport. A driver may have incomplete qualification records under Part 391 despite operating the vehicle safely.

An experienced litigator will look at this and ask whether the regulation addressed the very hazard that ultimately caused the collision.

Plaintiffs Use FMCSA Violations to Explain Why the Collision Was Foreseeable

Federal trucking regulations exist because regulators identified recurring safety hazards that were potentially responsible for catastrophic collisions. Plaintiffs may argue that the trucking company ignored certain risks despite there being regulations designed to prevent them.

Here are several examples:

• A fatigued driver rear-ended stopped traffic after exceeding the federal hours-of-service limits. Plaintiffs may argue that the collision occurred precisely because the regulations are put in place to prevent fatigue-related accidents.
• Brake maintenance records reveal that there were repeated violations before the truck failed to stop in a construction zone. In this case, plaintiffs may contend that an inspection would have caught the problem and prevented the mechanical failure.
• Improperly secured steel coils shifted during emergency braking, causing the trailer to overturn. In Part 393, cargo securements are outlined. If these are ignored, it may be stated that the rollover resulted from moving cargo.

Defense Challenges the Value of the Violation

Truck accident cases are won by demonstrating that the violations did or did not matter successfully. For example, a driver may have exceeded the permitted driving hours and was fatigued. However, if the accident occurred while they were stopped at a red light when another vehicle crossed the center line, the violation played no role in the outcome.

Likewise, a truck may have overdue maintenance records while electronic control module data, post-collision inspections, and accident reconstruction demonstrate that the braking system functioned normally before impact. In that circumstance, the defense may argue that the maintenance deficiencies, although genuine, had no causal relationship to the plaintiff’s injuries.

In Pennsylvania and New Jersey, negligence laws require plaintiffs to establish causation. Evidence that a federal regulation was violated can strengthen a negligence claim, but it does not eliminate the burden of proof that compliance would have changed the outcome.

As such, the defense counsel often focuses less on the violation and more on evidence that shows the collision would have occurred regardless.

Application Regulation Often Determines What Evidence Matters

Liability dictates the investigation in cases with an alleged FMCSA violation. An alleged hours-of-service violation will require more than driver logbooks. Experts may look at electronic logging device data, fuel receipts, toll records, GPS information, dispatch communications, surveillance footage, and cell phone records to determine if the driver’s recorded hours were accurately reflected.

If the claim instead involves inadequate vehicle maintenance, attention shifts to the inspection records, repair invoices, mechanic testimony, and maintenance policies. There are numerous instances where litigators can find evidence to support their argument. After all, regulation is not merely a legal standard. It points to where evidence can be found.

How Much Influence Does Expert Testimony Have in a FMCSA Violation Case?

In a truck accident, at least two points are undisputed. First, that the accident happened. Second, that an FMCSA violation occurred. Plaintiffs begin with expert evaluation. A trucking safety expert may explain how the carrier departed from accepted standards. However, without further testimony, such a claim of a violation cannot explain how or why the collision happened.

Rather than arguing that the trucking company complied with every applicable regulation, defense experts may accept the violation while maintaining that it had no practical effect on the events leading to the crash. A mechanical engineer may conclude that overdue brake maintenance did not affect braking performance. An accident reconstruction expert may testify that the truck could not have stopped even with a properly functioning braking system. A human factors expert may opine that driver fatigue played no role because the collision became unavoidable before any reasonable perception-reaction sequence could have prevented it.

Strategically, this is challenging for plaintiffs. Experts must be able to connect a regulatory violation to the mechanics of the collision. One tactic is to build a chain of proof in which the expert answers a question left open by a previous witness. The trucking safety expert explains the regulation. An engineer explains how violating the regulation altered the truck’s operation. In doing so, opinions are transformed into a persuasive theory of causation.

Conclusion

FMCSA violations occupy a unique role in catastrophic truck accident litigation because they frequently establish far more than technical noncompliance. When properly connected to the evidence, they explain why a collision was foreseeable, why it could have been prevented, and how the trucking company’s conduct departed from nationally recognized safety standards.

Ultimately, however, the regulations do not decide the case. Plaintiffs must still prove that the violation contributed to causing the collision, while defendants seek to demonstrate that the accident would have occurred regardless of any regulatory failure. The litigation therefore turns not on whether federal rules were broken, but on whether compliance with those rules would likely have changed the outcome.
