A collision between a passenger car and a fully loaded tractor-trailer is not simply a bigger version of an ordinary truck accident. The physics, the regulations, and the corporate structure behind the truck all change the case. At Scalli Murphy Law, P.C., attorney Christopher Murphy handles tractor-trailer and 18-wheeler crash claims across Massachusetts and understands what it takes to hold trucking companies accountable when their equipment or their drivers cause serious harm.
How Tractor-Trailer Crashes Happen and Why They Are So Severe
Big rigs fail differently than passenger vehicles, and the failures tend to be catastrophic. A jackknife occurs when the trailer swings out from behind the cab, often during hard braking or on wet pavement, and can sweep across multiple lanes of traffic. Underride crashes happen when a car slides beneath the trailer in a rear or side impact, frequently causing fatal roof and cabin intrusion. Override crashes, where the truck climbs over a smaller vehicle, carry similarly devastating consequences. Add in the “no-zones,” the wide blind spots along the sides and rear of a trailer where a driver simply cannot see a car, and highway speeds that leave little room for correction, and the risk multiplies. A loaded tractor-trailer can weigh twenty to thirty times more than a sedan, so even a low-speed impact can produce injuries far beyond what the same crash would cause between two passenger cars.

Who Can Be Held Responsible After a Truck Accident
Trucking cases rarely involve a single defendant. The driver may be an employee of the motor carrier or an independent owner-operator leased to it. The motor carrier that dispatched the load can bear responsibility for hiring, training, and supervision. The owner of the tractor or trailer, if different from the carrier, may share liability for maintenance failures. A freight broker that arranged the shipment can face claims for negligent selection of an unsafe carrier. When a load shifts or a trailer is improperly balanced, the company that loaded the cargo may also be at fault. Sorting out which entity, or combination of entities, caused a given crash requires reviewing lease agreements, dispatch records, and insurance policies early, before those relationships become harder to untangle.
What Makes Tractor-Trailer Accident Claims Different
Commercial trucking is governed by federal regulations that do not apply to ordinary drivers. Hours-of-service rules limit how long a driver may be behind the wheel without rest, and fatigue remains a recurring factor in serious highway crashes. Carriers must maintain qualification files, drug and alcohol testing records, and vehicle inspection reports. Under Federal Motor Carrier Safety Administration rules, most interstate carriers must maintain liability insurance of 750,000 dollars or more, which reflects how seriously federal regulators treat the risk these vehicles pose. Modern trucks also generate their own record of what happened: the electronic logging device (ELD) tracks hours and location, and the engine control module, sometimes called the truck’s black box, records speed, braking, and throttle data in the moments before a crash. That data is valuable evidence, but it is also routinely overwritten or purged on a schedule set by the carrier. A prompt written request to preserve this evidence, along with dash-cam footage and maintenance logs, helps prevent spoliation before it happens.

Evidence and Why Acting Early Matters
Because so much of the proof in a trucking case lives inside the carrier’s own systems, delay works against the injured person. Skid marks fade, vehicles get repaired or scrapped, and electronic logs cycle out. An early investigation can include photographs of the scene, the police report, witness statements, and a formal preservation letter sent to the carrier and its insurer. The same urgency applies whether the vehicle involved was a tractor-trailer, a dump truck, a delivery truck, or a hazmat carrier, each of which brings its own regulatory and evidentiary wrinkles. When a crash results in a death, the family’s legal options shift to a separate wrongful death claim, which carries its own procedures and timeline.
Deadlines and Shared Fault
Massachusetts law gives an injured person three years from the date of injury to file a personal injury lawsuit under G.L. c. 260, section 2A. Massachusetts also follows a modified comparative negligence rule under G.L. c. 231, section 85: a person found more than fifty percent at fault for the crash is barred from recovery, and any recovery is reduced by the injured person’s own share of fault. Because multiple parties, and multiple insurers, are often involved in a trucking case, how fault gets allocated among them can significantly affect the outcome.
