FMCSA Violations After a Truck Accident: What They Mean for Your Injury Claim

Last Updated: July 14, 2026

Commercial truck drivers and trucking companies must follow federal safety regulations intended to reduce preventable crashes. When these rules are ignored, an FMCSA violation may help explain why an 18-wheeler accident happened and whether the driver, motor carrier, or another company may be responsible.

These cases are rarely as simple as determining which driver received a traffic citation. A serious commercial truck crash may require an examination of electronic driving logs, inspection reports, driver qualification records, maintenance files, dispatch communications, cargo documents, and other evidence controlled by the trucking company.

Understanding federal trucking regulations can help injured people recognize why these claims require a different type of investigation than an ordinary passenger-vehicle collision. Our Houston truck accident lawyers investigate whether FMCSA violations, unsafe company practices, or failures throughout the commercial trucking operation contributed to a crash.

What Is the FMCSA?

The Federal Motor Carrier Safety Administration, commonly called the FMCSA, is an agency within the United States Department of Transportation. It regulates and oversees many aspects of commercial motor vehicle safety.

The agency establishes and enforces rules addressing subjects such as:

• Commercial driver hours and required rest periods
• Electronic logging devices and driving records
• Commercial driver licensing and medical qualifications
• Vehicle inspection, repair, and maintenance
• Drug and alcohol testing programs
• Cargo loading and securement
• Motor carrier safety practices and recordkeeping

These regulations are intended to reduce the risks created by large commercial vehicles, demanding delivery schedules, long driving shifts, mechanical failures, and unsafe carrier practices.

FMCSA rules are primarily contained within Title 49 of the Code of Federal Regulations. Different regulations may apply depending on the type of vehicle, cargo, route, driver, and commercial operation involved.

Why FMCSA Regulations Matter After a Truck Accident

FMCSA regulations can become important after a crash because they establish safety responsibilities that may go beyond the rules applicable to ordinary motorists.

For example, a passenger-vehicle driver is generally not required to maintain an electronic record of every hour spent driving. A regulated commercial driver may be required to document driving and on-duty time through an Electronic Logging Device, commonly called an ELD.

Similarly, a commercial motor carrier may be required to maintain driver qualification files, conduct inspections, document repairs, enforce drug and alcohol testing requirements, and monitor whether drivers comply with federal driving-hour limits.

If a serious truck crash occurs, these records may help answer questions such as:

• Was the driver too fatigued to operate safely?
• Did the driver exceed federal hours-of-service limits?
• Were electronic driving logs missing, inaccurate, or altered?
• Did the carrier hire a driver who was unqualified or medically unfit?
• Did the trucking company know that the truck had unsafe brakes or tires?
• Was cargo overloaded, improperly balanced, or inadequately secured?
• Did the company pressure the driver to violate safety rules to meet a deadline?

A thorough investigation does not stop with the truck driver’s version of events. It examines the entire commercial operation and the decisions made before the vehicle entered the roadway.

Who Must Follow FMCSA Regulations?

FMCSA regulations apply broadly to many motor carriers, commercial drivers, and commercial motor vehicles engaged in interstate commerce. However, the exact rules that apply can depend on the vehicle’s weight, passenger capacity, cargo, route, and other factors.

Regulated vehicles may include:

• 18-wheelers and tractor-trailers
• Semi-trucks and freight trucks
• Tanker trucks
• Flatbed trucks
• Commercial delivery vehicles
• Some buses and passenger-carrying vehicles
• Vehicles transporting hazardous materials

Some Texas commercial trucking operations may also be subject to state regulations. Determining which rules apply requires examining where the carrier operates, the type of vehicle involved, what it was transporting, and the nature of the commercial trip.

This is one reason commercial trucking claims require a more specialized investigation than most car accident cases. Learn more about the evidence, companies, and insurance issues involved on our Houston truck accident attorney page.

Common FMCSA Violations That Can Cause Truck Accidents

Not every trucking violation causes a collision. However, certain safety violations are frequently examined because they can increase the likelihood of driver fatigue, mechanical failure, loss of vehicle control, or other preventable hazards.

Common violations investigated after commercial truck accidents include:

• Exceeding hours-of-service limits
• Failing to take required driving breaks
• Using incomplete, inaccurate, or falsified electronic logs
• Operating a truck with unsafe brakes or tires
• Failing to complete required inspections
• Hiring or retaining an unqualified driver
• Failing to conduct required drug and alcohol testing
• Allowing an impaired driver to operate a commercial vehicle
• Improperly loading or securing cargo
• Operating an overloaded or unbalanced trailer
• Failing to repair a known mechanical defect
• Pressuring a driver to violate safety rules or delivery-hour limits

The records needed to identify these violations are often controlled by the trucking company or another commercial entity. They may not be included in the standard police crash report.

Hours-of-Service Violations

Driver fatigue is a serious concern in the trucking industry. Federal hours-of-service rules limit how long many commercial drivers may drive and remain on duty before resting.

According to the FMCSA’s official summary of hours-of-service regulations, property-carrying drivers are generally subject to several important limits:

• 11-hour driving limit: A driver may generally drive for a maximum of 11 hours after 10 consecutive hours off duty.
• 14-hour driving window: A driver generally may not drive beyond the 14th consecutive hour after coming on duty following 10 consecutive hours off duty.
• 30-minute break requirement: A qualifying driver must generally take a 30-minute interruption after eight cumulative hours of driving without a sufficient break.
• 60/70-hour limit: A driver generally may not drive after reaching 60 hours on duty in seven consecutive days or 70 hours in eight consecutive days, depending on the carrier’s operating schedule.

Exceptions and special provisions may apply, so driving records must be reviewed in context. However, a pattern of excessive driving hours may suggest that the driver was fatigued or that the motor carrier placed delivery demands ahead of public safety.

Evidence of an hours-of-service violation may include:

• ELD records
• Paper logs
• Fuel receipts
• Toll records
• GPS and telematics data
• Dispatch communications
• Bills of lading
• Pickup and delivery timestamps
• Cell phone records

Comparing these records can reveal whether the driver’s official log accurately reflects the trip. For example, a fuel receipt or toll record may place the truck on the road when the driver’s log claims the vehicle was stopped.

Electronic Logging Device Violations

Electronic Logging Devices automatically record certain information about a commercial driver’s activity and the movement of the truck. They are commonly used to track driving time and help enforce hours-of-service requirements.

The FMCSA provides an official overview of Electronic Logging Device requirements and resources.

Potential ELD-related violations may involve:

• Failing to use a required ELD
• Using an unregistered or noncompliant device
• Failing to maintain required supporting documents
• Entering inaccurate duty-status information
• Improperly editing driving records
• Using another person’s account or driver identification
• Failing to report or correct device malfunctions
• Pressuring a driver to falsify or manipulate logs

An ELD does not necessarily provide a complete picture by itself. Attorneys may compare ELD information with GPS records, dispatch messages, fuel purchases, toll data, vehicle telematics, and delivery records to identify inconsistencies.

This evidence can be especially important when a driver claims to have been adequately rested but the commercial records suggest otherwise.

Inspection, Repair, and Maintenance Violations

Commercial trucks travel long distances, carry heavy loads, and place substantial stress on tires, brakes, steering systems, coupling equipment, and other components. Federal regulations require motor carriers to systematically inspect, repair, and maintain regulated vehicles under their control.

Maintenance-related violations may include:

• Operating with worn or improperly adjusted brakes
• Using damaged, underinflated, or excessively worn tires
• Ignoring steering or suspension defects
• Failing to repair defective lights or reflective equipment
• Operating with damaged coupling devices
• Failing to conduct required inspections
• Failing to document repairs
• Returning an unsafe truck to service

Maintenance records may reveal whether a problem developed suddenly or had been reported repeatedly without being corrected. Driver vehicle inspection reports, roadside inspection results, repair invoices, work orders, and internal communications may all become relevant.

Responsibility may extend beyond the driver. Depending on the facts, the motor carrier, truck owner, leasing company, repair shop, maintenance contractor, or parts manufacturer could be involved.

Cargo Loading and Securement Violations

Cargo must be loaded and secured so that it does not shift, roll, leak, fall, or destabilize the commercial vehicle during transport. Improperly loaded cargo can change a trailer’s center of gravity, increase stopping distance, contribute to a rollover, or cause a driver to lose control.

The FMCSA’s official cargo securement rules explain requirements intended to prevent cargo from shifting within or falling from commercial motor vehicles.

Potential cargo-related violations may include:

• Using too few tiedowns
• Using damaged or inadequate securement devices
• Failing to block or brace cargo properly
• Failing to restrain items that may roll
• Exceeding weight limits
• Improperly distributing cargo weight
• Failing to inspect the load during transport
• Using defective trailer doors, locks, or containment systems

These cases may involve the motor carrier, truck driver, shipper, warehouse, freight company, cargo-loading contractor, or another party responsible for preparing the load.

If cargo falls from a truck or causes multiple vehicles to collide, determining who loaded, inspected, and controlled the shipment may be essential. People involved in a collision should preserve photographs, witness information, and other available evidence. Our guide on what to do after a Texas accident explains practical steps that may help protect a potential claim.

Driver Qualification and Training Violations

Motor carriers have a responsibility to determine whether their commercial drivers are properly licensed, medically qualified, and capable of safely operating the vehicles assigned to them. Hiring a driver is not simply a matter of confirming that the person possesses a commercial driver’s license.

Depending on the operation, a trucking company may be required to investigate and maintain records concerning the driver’s:

• Commercial driver’s license and required endorsements
• Employment application and prior driving experience
• Driving record and history of traffic violations
• Prior commercial driving employers
• Medical certification and physical qualifications
• Road test or equivalent certification
• Annual review of driving performance
• Drug and alcohol testing history

Potential driver qualification violations may arise when a motor carrier:

• Allows someone to drive without the proper commercial license or endorsement
• Fails to investigate the driver’s safety history before hiring
• Ignores prior crashes, disqualifying offenses, or serious traffic violations
• Permits a medically unqualified driver to operate a commercial vehicle
• Fails to provide appropriate training for the truck, trailer, route, or cargo involved
• Continues employing a driver after learning that the driver presents a safety risk
• Fails to properly supervise or monitor the driver’s performance

A driver qualification file may reveal that the trucking company knew—or should have known—that a driver was not prepared to operate safely. This evidence may support claims involving negligent hiring, training, supervision, retention, or entrustment, depending on the circumstances.

The investigation may also examine whether the driver had adequate experience operating the specific type of commercial vehicle involved. Driving a tanker truck, handling hazardous materials, operating a vehicle with multiple trailers, and transporting an oversized load may require specialized knowledge or endorsements.

Drug and Alcohol Testing Violations

Commercial drivers are subject to strict federal drug and alcohol rules. Motor carriers generally must maintain testing programs and prevent drivers from operating commercial vehicles when federal regulations prohibit them from doing so.

Testing may be required in circumstances involving:

• Pre-employment screening
• Random testing
• Certain commercial vehicle accidents
• Reasonable suspicion of drug or alcohol use
• Return-to-duty requirements
• Follow-up testing after a violation

Potential violations may include:

• Allowing a driver to operate after a positive drug or alcohol test
• Failing to perform a required pre-employment inquiry
• Failing to conduct required random testing
• Failing to perform post-accident testing when required
• Allowing a driver to return to work before completing required procedures
• Ignoring signs of impairment or substance misuse
• Failing to maintain accurate testing records
• Using an unqualified testing provider or improper testing procedure

FMCSA’s Drug and Alcohol Clearinghouse is a federal database containing certain records of commercial driver drug and alcohol program violations. An investigation may examine whether the carrier completed required inquiries and whether the driver was legally permitted to operate a commercial vehicle at the time of the crash.

Evidence of impairment may also come from police observations, toxicology results, witness statements, dash camera footage, receipts, cell phone records, or communications with the trucking company.

How FMCSA Violations Can Cause Truck Accidents

Federal trucking regulations address different safety risks, but violations often overlap. A single collision may result from several failures involving both the driver and the trucking company.

Examples include:

• A fatigued driver exceeds federal driving limits, fails to react to stopped traffic, and causes a rear-end collision.
• A carrier ignores repeated brake problems, and the truck cannot stop safely when traffic slows.
• An inexperienced driver receives inadequate training and loses control while navigating a curve or steep grade.
• Improperly secured cargo shifts inside the trailer, causing the truck to jackknife or roll over.
• An overloaded trailer increases stopping distance and places excessive strain on tires and braking components.
• A driver falsifies electronic logs to conceal excessive driving time and fatigue.
• A trucking company overlooks a disqualifying safety history and allows a dangerous driver to remain on the road.
• A maintenance provider fails to properly repair the truck, resulting in a tire, steering, or mechanical failure.

Investigating the violation is only part of the process. The evidence must also show how the unsafe conduct contributed to the collision and the resulting injuries.

Commercial truck crashes frequently cause traumatic brain injuries, spinal cord damage, amputations, internal injuries, severe fractures, and other life-changing harm. Learn more about the long-term damages involved in our overview of Texas catastrophic injury claims.

How Attorneys Investigate FMCSA Violations

Determining whether federal trucking violations contributed to a crash often requires evidence beyond the standard accident report. The trucking company and its insurers may possess many of the most important records.

A truck accident investigation may include obtaining and reviewing:

• Electronic Logging Device records documenting driving and on-duty time
• Engine Control Module or black box data showing speed, braking, throttle position, and other vehicle activity
• Driver qualification files containing licensing, medical, employment, and safety-history information
• Maintenance and inspection records showing reported defects, repairs, and service history
• Dispatch messages and delivery instructions revealing schedules or pressure placed on the driver
• GPS and telematics data documenting the truck’s route, movement, and location
• Dash camera footage capturing events inside or outside the truck
• Drug and alcohol testing records showing compliance with federal testing requirements
• Cargo records and bills of lading identifying the shipment, weight, loader, and responsible companies
• Roadside inspection and safety records documenting previous violations or out-of-service conditions
• Cell phone records that may reveal distraction or communications before the crash
• Police reports, photographs, video, and witness statements documenting the collision itself

These records should be compared rather than reviewed in isolation. A driver’s electronic log may appear compliant until it is compared with toll records, fuel receipts, GPS data, or delivery timestamps showing that the truck was moving during a claimed rest period.

Why Evidence Preservation Matters

Some electronic and corporate records may be overwritten, deleted, or discarded through routine business practices. That is why attorneys may send an evidence preservation letter—sometimes called a spoliation letter—soon after a serious commercial truck crash.

The letter may demand preservation of evidence such as:

• ELD and black box data
• Dash camera and surveillance footage
• Driver logs and qualification records
• Dispatch and internal communications
• Maintenance and inspection documents
• Drug and alcohol testing records
• GPS and telematics information
• The truck, trailer, tires, and damaged components

Prompt action can be especially important when the trucking company’s investigators and insurance representatives begin working immediately after the collision.

Does an FMCSA Violation Prove Negligence?

An FMCSA violation can be important evidence, but it does not automatically establish liability or guarantee compensation. The legal effect depends on the regulation involved, the facts of the crash, the party that violated the rule, and whether the violation contributed to the injuries.

A successful injury claim generally requires evidence showing:

1. A legal duty existed. The driver, motor carrier, or another party had a duty to act with reasonable care or comply with an applicable safety requirement.
2. The duty was breached. The party violated a regulation or otherwise failed to act reasonably.
3. The breach caused or contributed to the crash. The unsafe conduct must be connected to the collision rather than merely being an unrelated paperwork violation.
4. The victim suffered damages. The crash caused injuries, medical expenses, lost income, pain, impairment, or other legally recoverable losses.

For example, a carrier’s failure to update an administrative document may have little connection to a rear-end collision. In contrast, ELD records showing that a driver exceeded federal driving limits before falling asleep may be directly relevant to causation.

The trucking company may also argue that the injured person contributed to the accident. Texas uses a modified comparative responsibility system, which can reduce or prevent recovery depending on the percentage of fault assigned. Our Texas comparative fault guide explains how shared responsibility may affect an injury claim.

Who May Be Liable for an FMCSA Violation?

The truck driver is not automatically the only responsible party. Commercial trucking operations commonly involve several businesses that perform different functions, own different equipment, or control different parts of the shipment.

Depending on the evidence, potentially responsible parties may include:

The Commercial Truck Driver

A driver may be responsible for speeding, distracted driving, fatigue, impairment, unsafe lane changes, falsified logs, inspection failures, or other negligent conduct.

The Motor Carrier or Trucking Company

A motor carrier may be responsible for its own negligence involving hiring, training, supervision, retention, maintenance, scheduling, regulatory compliance, or pressure placed on drivers to meet unsafe deadlines.

The Truck or Trailer Owner

A separate company may own or lease the tractor, trailer, or other equipment. Its maintenance responsibilities and knowledge of defects may become relevant.

The Cargo Loader or Shipper

A warehouse, shipper, loading contractor, or another company may be responsible when improperly loaded, overloaded, or unsecured cargo contributes to the crash.

A Maintenance or Repair Company

An outside service provider may share responsibility if negligent inspection or repair work allowed unsafe brakes, tires, steering components, or other equipment to remain in service.

A Freight Broker or Other Commercial Entity

Depending on the facts and applicable law, a freight broker or another company involved in arranging transportation may face claims based on its own conduct. These claims are highly fact-specific and can involve complicated federal issues.

A Vehicle or Parts Manufacturer

A manufacturer may be involved if a defective tire, braking system, steering component, coupling device, trailer component, or other product contributed to the collision.

Identifying all responsible parties is important because each may possess different evidence, insurance coverage, and legal duties. Our Houston truck accident attorneys investigate the entire commercial operation rather than assuming the crash resulted solely from a driver’s mistake.

What to Do After a Commercial Truck Accident

The moments after a serious truck crash can be overwhelming. Your immediate priority should be obtaining medical care and protecting yourself from further harm.

When possible, the following steps may help protect your health and potential claim:

1. Call 911 and report the collision. Request emergency medical assistance when anyone may be injured.
2. Seek prompt medical treatment. Some serious injuries may not be immediately obvious because of shock or adrenaline.
3. Photograph the scene. Capture the vehicles, truck and trailer numbers, company markings, cargo, roadway conditions, skid marks, debris, and visible injuries.
4. Collect witness information. Independent witnesses may leave before the investigation is complete.
5. Identify the commercial parties. Record the driver’s information, motor carrier name, USDOT number, license plate, trailer number, and insurance details when available.
6. Avoid admitting fault. Provide accurate information without speculating about what caused the crash.
7. Preserve documents and damaged property. Keep medical records, receipts, photographs, clothing, and other relevant evidence.
8. Be cautious with insurance adjusters. A trucking insurer may request a recorded statement before you understand the extent of your injuries or your legal rights.
9. Consider obtaining legal guidance promptly. Important trucking records and electronic data may not be preserved indefinitely.

Before providing a recorded statement to an insurance company, review our Texas recorded statement guide to understand how your answers may affect an injury claim.

Frequently Asked Questions About FMCSA Violations

What does FMCSA stand for?

FMCSA stands for the Federal Motor Carrier Safety Administration. It is the federal agency responsible for regulating and overseeing many aspects of commercial motor vehicle safety.

What are the most common FMCSA violations after a truck accident?

Common violations involve hours-of-service limits, electronic logging devices, vehicle maintenance, driver qualifications, drug and alcohol testing, cargo securement, inspections, and recordkeeping. The relevant violation depends on how the crash occurred.

Can I look up a trucking company’s FMCSA violations?

Some carrier registration, inspection, crash, and safety information may be publicly available through federal databases. However, public information may not include every record needed to investigate a specific accident. Driver files, electronic data, maintenance documents, dispatch communications, and internal company records may require formal preservation and discovery.

Does an FMCSA violation automatically make the trucking company liable?

No. A violation may provide evidence of negligence, but it must generally be connected to the cause of the collision and the resulting injuries. An unrelated administrative violation may not establish liability by itself.

Can a trucking company be responsible for a driver’s violation?

Potentially. A carrier may be responsible for its own conduct involving hiring, training, supervision, maintenance, scheduling, or regulatory compliance. It may also face responsibility based on its relationship with the driver, depending on the facts and applicable law.

What is an hours-of-service violation?

An hours-of-service violation occurs when a regulated commercial driver fails to comply with federal limits governing driving time, on-duty time, required rest periods, or recordkeeping. These violations may be especially important when fatigue contributed to the crash.

What is an ELD violation?

An ELD violation may involve failing to use a required Electronic Logging Device, entering inaccurate information, improperly editing records, failing to address a malfunction, or attempting to conceal excessive driving time.

How long does a trucking company keep electronic evidence?

Retention periods vary according to the record and applicable regulation, and some vehicle systems may overwrite data much sooner than formal corporate records are discarded. Prompt evidence preservation is therefore important after a serious crash.

What if the truck driver was an independent contractor?

Calling a driver an independent contractor does not automatically resolve liability. The investigation may examine the motor carrier’s operating authority, control over the driver, ownership or leasing arrangements, dispatch practices, insurance coverage, and the roles of other commercial entities.

What damages may be available after an FMCSA-related truck accident?

Depending on the circumstances, recoverable damages may include medical expenses, future medical care, lost wages, reduced earning capacity, physical pain, mental anguish, impairment, disfigurement, property damage, and other losses recognized under Texas law.

How long do I have to file a Texas truck accident claim?

Texas personal injury lawsuits are generally subject to a two-year statute of limitations, but exceptions and shorter notice requirements may apply in some cases. Waiting can also make evidence more difficult to preserve, so injured people should not rely on the filing deadline as a reason to delay an investigation.

Should I speak with the trucking company’s insurance adjuster?

You should use caution. The adjuster represents the insurance carrier and may seek information that limits the company’s financial exposure. Consider obtaining legal guidance before providing a recorded statement, signing a release, or accepting a settlement.
