In the United States, and here in Massachusetts, commercial motor vehicles are strictly regulated. A complex web of state and federal laws and regulations govern the trucking industry, mandating everything from who can drive a commercial motor vehicle to how long a trucker can be on the road without taking a break. As a result, any claim for a tractor-trailer collision necessarily involves an investigation into whether any of these rules were violated. In addition, truck accident lawsuits often involve more than just the at-fault driver and their insurance company. Truck drivers are typically employed by trucking companies. Under the doctrine of respondeat superior, employers may be held liable for the negligence of their employees -- and so a lawsuit may be filed against the trucker, their employer, and possibly other parties. Truck crashes also tend to involve more serious or even fatal injuries. While any motor vehicle accident can cause severe injuries, because commercial trucks are so much bigger and heavier than passenger vehicles, the potential for catastrophic injuries is much higher. To increase the likelihood of recovering for the full extent of losses in this type of case, it is important to work with a Worcester personal injury lawyer with experience handling truck accidents.
