The 5 FMCSA Violations That Trigger Lawsuits

What Motor Carriers Need to Know to Reduce Legal Risk 

For motor carriers, compliance with the Federal Motor Carrier Safety Regulations (FMCSRs) is often viewed as a regulatory obligation. However, in practice, these

regulations play a central role in trucking litigation and accident investigations. 

When a crash occurs involving a commercial motor vehicle, investigators, regulators, and plaintiff attorneys typically examine whether the motor carrier followed the required safety standards. These federal regulations establish the minimum safety requirements for motor carriers and drivers operating commercial vehicles in interstate commerce.  

If violations are discovered, they can significantly increase a company’s exposure to lawsuits, enforcement actions, and financial liability. 

Below are five of the most common FMCSA compliance failures that frequently lead to litigation. 

1. Driver Qualification Violations 

One of the first areas investigators examine after a trucking accident is whether the driver was properly qualified to operate a commercial motor vehicle (CMV). 

Federal regulations require motor carriers to ensure their drivers meet minimum qualifications before operating a commercial vehicle. These requirements include: 

• Being at least 21 years old for interstate operations 

• Holding a valid commercial driver’s license (CDL) 

• Being physically qualified to operate a CMV 

• Demonstrating the ability to drive safely  

Motor carriers must also maintain a driver qualification file for each driver containing employment applications, driving records, and safety history. 

When these files are incomplete or missing, carriers can face claims of negligent hiring or negligent retention, especially if the driver had a history of safety violations. 

2. Hours-of-Service Violations 

Driver fatigue is one of the most serious safety risks in the trucking industry. For that reason, FMCSA regulations establish strict Hours-of-Service (HOS) limits that control how long drivers can operate commercial vehicles. 

In general, property-carrying drivers may drive no more than 11 hours after 10 consecutive hours off duty.  

Additional restrictions include limits on total duty time and required rest breaks to ensure drivers remain alert while operating vehicles. 

Violations of these rules can create significant liability if a crash occurs. In litigation, driver logs, electronic logging device (ELD) records, and dispatch communications are often reviewed to determine whether a company allowed or required a driver to exceed legal limits. 

3. Vehicle Maintenance and Inspection Failures 

Commercial vehicles must be maintained in safe operating condition at all times. 

Federal regulations require motor carriers to systematically inspect, repair, and maintain all commercial motor vehicles under their control.  

Maintenance failures frequently cited in crash investigations include: 

• brake system defects 

• tire failures 

• steering issues 

• defective lighting or signals 

Carriers must also maintain detailed maintenance records and inspection reports. 

If a crash is linked to mechanical failure, missing maintenance documentation can significantly increase legal exposure. 

4. Poor Safety Monitoring and CSA Performance 

FMCSA monitors motor carriers using the Compliance, Safety, Accountability (CSA) program, which analyzes safety performance based on inspection results, crash reports, and regulatory violations.  

Carriers with high violation rates may be prioritized for: 

• warning letters 

• safety audits 

• compliance investigations 

In litigation, plaintiff attorneys often review CSA data to argue that a company had a pattern of unsafe practices and failed to correct known safety problems. 

Ignoring safety metrics or failing to address recurring violations can therefore increase a carrier’s legal risk. 

5. Drug and Alcohol Testing Violations 

Motor carriers must implement a controlled substances and alcohol testing program for drivers operating commercial motor vehicles. 

Federal rules require several types of testing, including: 

• pre-employment drug testing 

• random testing 

• post-accident testing 

• reasonable suspicion testing  

Failure to implement or properly administer these programs can lead to severe liability if an impaired driver is involved in an accident. 

In addition to civil litigation risk, violations may result in FMCSA enforcement actions and substantial financial penalties. 

Why Compliance Matters 

FMCSA regulations are designed to reduce crashes, injuries, and fatalities involving large trucks and buses.  

For motor carriers, compliance is not simply about avoiding fines or passing inspections. It is also a critical component of risk management and legal protection. 

Companies that maintain strong safety programs and accurate documentation are far better positioned to: 

• defend against accident claims 

• respond to regulatory investigations 

• reduce operational and financial risk 

The trucking industry operates within one of the most heavily regulated transportation environments in the United States. Understanding and following FMCSA safety rules is essential not only for operational safety but also for protecting businesses from costly litigation. 

Motor carriers that treat safety compliance as a core business function — rather than a regulatory burden — are far more likely to operate successfully in today’s transportation landscape. 

Proactive compliance is one of the most effective ways to reduce litigation risk. Esquivel Law Chartered works with motor carriers to evaluate safety practices, address regulatory gaps, and build defensible compliance programs.
