A collision involving a commercial truck is very different from an ordinary car accident. While most drivers focus on police reports, insurance information, and vehicle damage, truck accident investigations often involve an entirely different set of rules that can significantly affect who is responsible for the crash.

Those rules come from the Federal Motor Carrier Safety Administration(FMCSA)—the federal agency responsible for regulating the commercial trucking industry throughout the United States. The FMCSA establishes safety standards designed to reduce preventable crashes involving tractor-trailers, semi-trucks, box trucks, and other commercial motor vehicles.

When these regulations are violated, they may become important evidence in a New Jersey truck accident claim. A trucking company that failed to properly maintain its vehicles, required a driver to work beyond legal limits, or ignored mandatory safety inspections could potentially face additional liability beyond the actions of the driver alone.

AtKhorozian Law Group, Attorney Linda Khorozian understands that commercial truck accidents often require a much more extensive investigation than ordinary New Jersey car accidents. Identifying potential FMCSA violations is one of many steps that may be necessary to determine liability and preserve critical evidence after a serious crash.

A commercial truck undergoes a roadside safety inspection on a New Jersey highway. Federal FMCSA regulations governing inspections, maintenance, and driver compliance can play a critical role in truck accident investigations.

What Is the FMCSA?

The Federal Motor Carrier Safety Administration (FMCSA) is a division of the U.S. Department of Transportation responsible for promoting safety within the commercial trucking industry.

The agency establishes nationwide regulations governing:

• Commercial driver qualifications
• Hours of Service (HOS)
• Vehicle inspections
• Maintenance requirements
• Drug and alcohol testing
• Cargo securement
• Electronic Logging Devices (ELDs)
• Driver medical certification
• Safety records

These rules apply to many commercial vehicles operating on New Jersey highways, including:

• Tractor-trailers
• Semi-trucks
• Box trucks
• Delivery trucks
• Freight carriers
• Interstate commercial vehicles

Many drivers are surprised to learn that trucking companies are subject to far more regulations than ordinary passenger vehicle drivers.

Why FMCSA Regulations Matter After a Truck Accident

Every truck accident investigation begins with one important question:

What caused the collision?

Sometimes the answer is straightforward.

Other times, the truck driver's actions are only one piece of the puzzle.

Investigators may also examine whether:

• The trucking company ignored federal safety regulations.
• Required inspections were skipped.
• Maintenance problems were overlooked.
• The driver exceeded legal driving hours.
• Cargo was improperly loaded.
• Mechanical defects contributed to the collision.

Evidence of FMCSA violations can help explain why the accident occurred—not simply how it happened.

Hours of Service Rules Can Prevent Fatigue-Related Crashes

One of the most well-known FMCSA regulations involves Hours of Service (HOS) limits.

Commercial drivers are not permitted to drive indefinitely.

Federal regulations establish maximum driving hours designed to reduce fatigue-related crashes.

These rules generally limit:

• Daily driving time.
• Weekly driving hours.
• Required off-duty periods.
• Mandatory rest breaks.

Fatigue remains one of the leading contributors to commercial truck accidents nationwide. A driver who has been behind the wheel too long may experience slower reaction times, poor judgment, and reduced awareness—creating dangerous conditions for everyone sharing the road.

If a trucking company knowingly encourages drivers to violate these limits, that information could become highly relevant during a personal injury investigation.

Driver Qualification Files May Reveal Safety Problems

Federal regulations require trucking companies to maintain detailed qualification files for commercial drivers.

These records often include:

• Commercial driver's license information.
• Medical certifications.
• Driving history.
• Previous crashes.
• Safety violations.
• Employment records.
• Required training documentation.

These records may help determine whether a trucking company hired or retained a driver who should not have been operating a commercial vehicle.

Vehicle Maintenance Requirements

Commercial trucks travel thousands of miles each week.

Because of this, FMCSA regulations require carriers to inspect, repair, and maintain their vehicles regularly.

Maintenance records may reveal problems involving:

• Brake systems.
• Tires.
• Steering components.
• Lights.
• Coupling devices.
• Suspension.
• Emergency equipment.

A mechanical failure caused by poor maintenance may expose both the trucking company and other responsible parties to additional liability.

Our Truck Accident Lawyer page explains why preserving maintenance records can be just as important as obtaining the police report after a serious collision.

Electronic Logging Devices (ELDs) Replace Paper Logbooks

Most commercial carriers now use Electronic Logging Devices (ELDs) instead of handwritten logbooks.

ELDs automatically record information such as:

• Driving hours.
• Engine operation.
• Vehicle movement.
• Rest periods.
• Duty status.

These electronic records often become valuable evidence when determining whether a driver complied with federal Hours of Service regulations.

Unlike witness testimony, electronic data frequently provides an objective timeline of the driver's activities before the collision.

Drug and Alcohol Testing May Become Critical Evidence

Commercial drivers are subject to strict FMCSA drug and alcohol testing regulations. Depending on the circumstances of a collision, trucking companies may be required to conduct post-accident testing to determine whether alcohol or controlled substances played a role.

When required testing is delayed, incomplete, or not performed, important evidence may be lost. Investigators often review:

• Post-accident drug and alcohol test results
• Prior testing history
• Employer compliance records
• Company safety policies

While not every truck accident involves impairment, compliance with FMCSA testing requirements is an important part of a thorough investigation.

Cargo Securement Violations Can Lead to Serious Accidents

Improperly loaded or unsecured cargo can dramatically affect how a commercial truck handles on the road.

Cargo that shifts unexpectedly may cause a driver to:

• Lose control during a turn.
• Jackknife.
• Rollover.
• Cross into adjacent lanes.
• Spill debris into traffic.

Federal regulations establish detailed cargo securement requirements because improperly loaded trucks pose a significant risk to everyone on the roadway.

Depending on the facts, liability may extend beyond the truck driver to the company responsible for loading or securing the cargo.

Black Box Data Can Tell the Story of the Crash

Many commercial trucks are equipped with Electronic Control Modules (ECMs) or Event Data Recorders—commonly referred to as a truck's "black box."

These systems may record valuable information, including:

• Vehicle speed
• Brake application
• Engine performance
• Steering inputs
• Throttle position
• Sudden deceleration
• Time of impact

This information can help investigators reconstruct how a crash occurred and determine whether the driver attempted to avoid the collision.

Important Evidence Can Disappear Quickly

Unlike ordinary passenger vehicle accidents, commercial trucking companies maintain large volumes of electronic and paper records.

Some records are preserved only for limited periods unless steps are taken to preserve them.

Potential evidence includes:

• Driver qualification files.
• Electronic Logging Device (ELD) data.
• Maintenance records.
• Inspection reports.
• Dash camera footage.
• Dispatch communications.
• GPS records.
• Driver logbooks.
• Cell phone records.
• Black box downloads.

Because certain records may be overwritten or destroyed in the normal course of business, preserving evidence early can be extremely important.

Who May Be Liable Besides the Truck Driver?

One of the biggest misconceptions after a commercial truck accident is that the driver is always the only responsible party.

Depending on the investigation, liability may also involve:

• The trucking company.
• The company that owns the trailer.
• A maintenance contractor.
• The cargo loading company.
• A vehicle manufacturer.
• Another negligent driver.
• A parts manufacturer.
• A government entity responsible for roadway maintenance, in limited circumstances.

Determining liability often requires reviewing FMCSA records alongside police reports, witness statements, and physical evidence from the accident scene.

Why Truck Accident Cases Are Different From Regular Car Accidents

Truck accident claims frequently involve:

• Multiple insurance policies.
• Federal safety regulations.
• Commercial carriers.
• Preservation of electronic evidence.
• Corporate defendants.
• Extensive maintenance records.
• Higher insurance limits.
• More severe injuries.

These additional factors often make commercial truck accident cases more complex than ordinary passenger vehicle collisions.

Attorney Linda Khorozian understands the importance of identifying all potentially responsible parties and pursuing every available source of compensation for injured clients. Learn more about how these cases differ by visiting our Truck Accident page.

Frequently Asked Questions

What is the FMCSA?

The Federal Motor Carrier Safety Administration (FMCSA) is the federal agency responsible for regulating commercial trucking safety throughout the United States.

Do FMCSA rules apply to every truck accident?

They generally apply to commercial motor carriers and drivers operating vehicles that fall under federal regulations. Whether a specific regulation applies depends on the facts of the case.

Can an FMCSA violation help prove negligence?

Potentially. Evidence that a trucking company or driver violated applicable safety regulations may become relevant when determining liability, depending on the circumstances.

How long is trucking company evidence preserved?

Some records are maintained only for limited periods. Because retention requirements vary, preserving evidence promptly after a collision can be important.

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

You should be cautious before providing recorded statements. Understanding your legal rights before discussing the accident with the trucking company's insurer may help protect your claim.

Protect Your Rights After a New Jersey Truck Accident

Truck accidents are rarely simple. Beyond the immediate injuries and property damage, these cases often involve federal regulations, multiple insurance policies, commercial carriers, and evidence that can disappear quickly if it is not preserved.

Understanding the role of FMCSA regulations is just one part of protecting your rights after a serious collision. A thorough investigation may reveal issues involving driver fatigue, vehicle maintenance, cargo securement, Hours of Service violations, or other safety concerns that are not immediately apparent at the crash scene.

Attorney Linda Khorozian is committed to helping injured victims understand their legal options and ensuring that every available source of evidence is thoroughly investigated.
