Who Can Be Held Liable in a Truck Accident in Massachusetts?

February 27, 2026

Truck accidents are often more complex than standard motor vehicle collisions because multiple parties may be legally responsible. Unlike a typical car crash involving two drivers, truck accident cases frequently involve commercial trucking companies, contractors, maintenance providers, and other corporate entities.

In Massachusetts, potentially liable parties in a truck accident include the truck driver, the trucking company, third-party maintenance contractors, cargo loading companies, and vehicle or parts manufacturers. Liability depends on the specific circumstances of the crash and which parties acted negligently or violated federal safety regulations. Identifying every responsible party is critical for pursuing full compensation after a serious truck accident.

Why Truck Accident Liability Is More Complex Than Car Accidents

Commercial trucking is a heavily regulated industry governed by both Massachusetts state law and federal safety regulations enforced by the Federal Motor Carrier Safety Administration (FMCSA). Truck drivers operating on highways like I-90, I-93, and I-95 through Massachusetts must comply with strict rules regarding hours of service, vehicle maintenance, cargo loading, and driver qualifications.

When a crash occurs, investigators must determine whether those rules were violated and whether negligence by any party contributed to the accident. Because commercial trucks are operated for business purposes, liability often extends well beyond the driver alone.

Truck accidents on Massachusetts roadways frequently involve multiple liable parties, larger insurance policies, and more aggressive defense strategies than standard car accident claims. Understanding the full scope of potential liability is essential to building a strong case.

Potentially Liable Parties in a Massachusetts Truck Accident

1. The Truck Driver

A truck driver may be personally liable if they acted negligently by:

  • Driving while fatigued in violation of FMCSA hours-of-service rules (49 CFR Part 395)
  • Speeding or driving recklessly
  • Using a mobile device while driving
  • Operating under the influence of drugs or alcohol
  • Failing to comply with Massachusetts traffic laws

Driver negligence is typically the starting point in any truck accident liability investigation. However, the driver is rarely the only party at fault.

2. The Trucking Company

In many cases, the trucking company that employs or contracts with the driver is legally responsible under the doctrine of vicarious liability. This legal principle holds employers accountable for the actions of employees performed within the scope of their employment.

A trucking company may also be directly liable if it:

  • Failed to properly train or supervise the driver
  • Encouraged unsafe scheduling practices or pressured drivers to exceed hours-of-service limits
  • Ignored FMCSA safety regulations
  • Failed to conduct adequate background checks or drug testing as required by 49 CFR Part 382
  • Maintained unsafe vehicles or neglected required inspections under 49 CFR Part 396

Trucking companies typically carry substantial commercial insurance policies, often $1 million or more, which is why these claims are aggressively defended by experienced insurance defense teams.

3. Maintenance and Repair Contractors

Commercial trucks require regular inspection and maintenance to remain safe for highway operation. If brake failure, tire blowouts, or steering system defects contributed to the crash, the third-party maintenance company responsible for servicing the vehicle may share liability.

Maintenance records are critical evidence in these cases. FMCSA regulations require trucking companies to maintain detailed inspection and repair logs under 49 CFR Part 396, and gaps or falsifications in those records can be strong indicators of negligence.

4. Cargo Loading Companies

Improperly loaded or unsecured cargo can cause jackknife accidents, rollovers, and shifting-weight collisions. If a separate cargo company was responsible for loading the truck, that entity may be partially liable for the accident.

FMCSA cargo securement rules (49 CFR Part 393, Subpart I) establish specific requirements for how different types of freight must be loaded and secured. Violations of these standards can serve as direct evidence of negligence.

5. Vehicle or Parts Manufacturers

If a mechanical defect contributed to the accident, such as defective brakes, steering components, tires, or coupling devices, a product liability claim may arise against the vehicle manufacturer or parts supplier. These claims are separate from negligence claims and may be pursued under strict liability principles.

Federal Trucking Regulations and Liability in Massachusetts

Truck drivers and trucking companies operating in Massachusetts are subject to FMCSA regulations that establish baseline safety standards for the industry. Key regulatory areas include:

  • Hours of Service (49 CFR Part 395): Limits on consecutive driving hours and mandatory rest periods to prevent fatigue-related accidents
  • Electronic Logging Devices (49 CFR Part 395, Subpart B): Required digital tracking of driver hours to prevent falsification of paper logs
  • Drug and Alcohol Testing (49 CFR Part 382): Pre-employment, random, and post-accident testing requirements for commercial drivers
  • Vehicle Maintenance and Inspection (49 CFR Part 396): Mandatory inspection schedules and repair documentation
  • Driver Qualification Standards (49 CFR Part 391): Minimum age, medical fitness, and licensing requirements

Violations of these federal safety regulations can serve as powerful evidence of negligence in a Massachusetts truck accident case. An experienced attorney will know how to obtain and analyze these records to identify regulatory violations that contributed to the crash.

Comparative Negligence in Massachusetts Truck Accident Cases

Massachusetts follows a modified comparative negligence rule under Mass. Gen. Laws Ch. 231, § 85. Under this statute, an injured person may recover damages as long as their own negligence does not exceed 50 percent of the total fault. If the injured party is found to be 51 percent or more at fault, they are barred from recovering any compensation.

Any damages awarded are reduced in proportion to the injured person's share of fault. For example, if an injured truck accident victim is found to be 20 percent at fault and their total damages are $500,000, the recovery would be reduced by 20 percent to $400,000.

Truck accident cases often involve aggressive attempts by insurance companies to shift blame to the injured driver. Insurers may argue that the victim was speeding, failed to maintain a safe following distance, or was otherwise negligent. A thorough investigation is critical to preventing unfair fault allocation and protecting the injured party's right to full compensation.

Why Identifying All Liable Parties Matters

Truck accidents often result in catastrophic injuries that require extensive medical care, long-term rehabilitation, and significant financial support. Understanding why truck accidents often result in catastrophic injuries is an important context when evaluating the full scope of a liability claim.

Identifying every liable party ensures:

  • Access to multiple insurance policies: Each responsible party may carry separate coverage, increasing the total available compensation
  • Higher available coverage limits: Commercial trucking policies often provide significantly more coverage than personal auto insurance
  • Full recovery of long-term damages: Catastrophic injuries may require lifetime medical care, and multiple sources of recovery may be necessary to cover those costs
  • Accountability for corporate negligence: Trucking companies and their contractors should be held responsible when their practices contribute to serious injuries

Failing to name all responsible parties can significantly limit the compensation available to a seriously injured victim.

How Liability Is Proven in Massachusetts Truck Accident Cases

Proving liability in a truck accident typically requires a more extensive investigation than a standard car crash. Critical steps include:

  • Reviewing police reports and crash data to establish the initial facts of the collision
  • Securing electronic control module (black box) data that records speed, braking, and other vehicle performance metrics before and during the crash
  • Analyzing driver logs and ELD records to identify hours-of-service violations or falsified records
  • Examining maintenance and inspection records to uncover deferred repairs or missed inspections
  • Interviewing witnesses and obtaining surveillance footage from nearby businesses or traffic cameras
  • Retaining accident reconstruction experts to analyze physical evidence and determine how the crash occurred

Because trucking companies and their insurers move quickly to protect their interests after a serious accident, early legal intervention is critical to preserving evidence before it is altered, destroyed, or lost.

What to Do After a Truck Accident in Massachusetts

If you have been involved in a truck accident on Massachusetts roadways, taking the right steps early can help protect your ability to pursue full compensation:

  1. Seek medical attention immediately. Some injuries, including traumatic brain injuries and internal organ damage, may not be immediately apparent.
  2. Report the accident to police. An official accident report documents the scene and initial findings.
  3. Do not provide a recorded statement to the trucking company's insurance carrier without consulting an attorney.
  4. Preserve all evidence. If possible, take photos of the vehicles, the scene, road conditions, and any visible injuries.
  5. Contact an experienced truck accident attorney. Early legal involvement ensures evidence is preserved and all liable parties are identified before critical records are lost.

It is also important to understand that Massachusetts has a three-year statute of limitations for personal injury claims under Mass. Gen. Laws Ch. 260, § 2A. This means you generally have three years from the date of the accident to file a lawsuit. Missing this deadline can permanently bar your ability to seek compensation.

Frequently Asked Questions

Can more than one party be liable in a truck accident?

Yes. Truck accident cases frequently involve multiple liable parties. The truck driver, the trucking company, maintenance contractors, cargo loading companies, and vehicle manufacturers may all share responsibility depending on the circumstances of the crash. Each party may carry separate insurance coverage, which can increase the total compensation available to the injured victim.

Are trucking companies always responsible for their drivers?

In many cases, yes. Under the legal doctrine of vicarious liability, employers are generally responsible for the negligent actions of their employees when those actions occur within the scope of employment. However, the specific facts of each case matter. If a driver was engaged in personal activity at the time of the crash, the analysis may differ.

What if the trucking company claims the driver was an independent contractor?

Trucking companies sometimes attempt to avoid liability by classifying drivers as independent contractors rather than employees. Massachusetts courts examine the actual level of control the company exercised over the driver, including factors like scheduling, route assignments, equipment ownership, and compliance requirements. Courts often look beyond the contractual label to determine the true nature of the working relationship.

How long do I have to file a truck accident lawsuit in Massachusetts?

Under Mass. Gen. Laws Ch. 260, § 2A, you generally have three years from the date of the accident to file a personal injury lawsuit. However, acting quickly is important because critical evidence, including electronic logging data, maintenance records, and black box information, can be lost or overwritten if not promptly preserved.

What types of compensation can I recover in a truck accident case?

Truck accident victims may be entitled to compensation for medical expenses (current and future), lost wages, loss of earning capacity, pain and suffering, emotional distress, and other long-term damages. In cases involving catastrophic injuries, lifetime medical care costs and loss of quality of life may also be recoverable.
