How is Liability Determined in Philadelphia Truck Accident Cases?

According to the latest figures from the Pennsylvania Department of Transportation, Philadelphia has one of the highest rates of trucking accidents in the Commonwealth. In 2024, of the 110,765 vehicle accidents in Pennsylvania, 7,312 involved a heavy truck.
Though truck accidents are not uncommon, determining liability in truck accident cases continues to be a complex issue. Truck accident cases can involve multiple defendants, and there may be disputes over who caused the crash. A Philadelphia truck accident lawyer can help you navigate these issues and get the compensation you need. We work with investigators, experts, and advanced technology to determine liability in your truck accident case.
While a passenger vehicle driver can be liable for a truck accident due to negligence, failure to follow highway rules, intoxication, etc., liability is often with the truck driver, the trucking companies, or another party.
When a Truck Driver is at Fault for a Crash
Whenever truck drivers get behind the wheel of a semi-truck, they have an immense responsibility to drive carefully. If a truck driver is negligent or fails to drive with reasonable care, they can be held liable for a truck accident.
Though truck driver negligence is a leading cause of truck accidents, some of the most common causes of truck accidents where truck drivers may be found liable include:
- Fatigued driving: Drivers are only permitted to drive for so many hours under the Federal Motor Carrier Safety Administration. This includes taking breaks after eight hours of consecutive driving, getting enough sleep, etc. When drivers do not take the breaks required under these federal regulations, it can result in fatigued driving and major truck accidents.
- Driver error: Even with extensive training, errors can still occur. Be it ineffective maneuvering of a large truck around back roads, inability to stop, blind spots, etc., these can cause accidents.
- Driving under the influence: There are laws and regulations within the trucking industry that prohibit truck drivers from operating big rigs after the consumption of alcohol, drugs, etc. However, when a driver drinks and drives, fatal crashes can occur.
- Distracted driving: Whenever a truck driver takes his or her eyes away from the road, they are considered distracted. From simple acts like taking a phone call to adjusting dashboard controls, a few seconds of distraction can lead to serious injuries.
When The Trucking Company is at Fault
As much as the driver of other vehicles can be held liable, so too can the trucking company they drive for. When a trucker is employed by a trucking company, the company can be held liable for its employees’ negligent actions. Additionally, the trucking company can be held liable for its own negligent hiring, training, or safety practices that contributed to your truck accident.Reasons trucking companies may be found liable in a truck accident include:
- The commercial truck was not properly maintained by the company: Unless the truck driver owns the semi, the trucking company is required to maintain the vehicle. However, when they allow vehicle defects to go untreated, tractor trailers can become dangerous to operate, leading to collisions.
- Commercial drivers were not adequately trained: Transportation companies can be found negligent if they fail to adequately vet and train their drivers. Truck drivers have to undergo rigorous training in order to operate these large commercial vehicles. However, given the size and weight of these large trucks, if the driver is not well-equipped to drive these long hauls in various terrain, the truck companies can be held at fault in the event of a truck accident.
- Truck drivers were made to adhere to strict deadlines and unrealistic demands: Many truck drivers will tell you that driving a big rig is a stressful job. When you add that stress to deadlines and unrealistic assignments that these drivers must meet, they may not be able to control the schedule they are placed on, putting themselves and other drivers at risk.
When Other Parties Are At Fault
While the trucking companies or the truck driver are two of the most common negligent parties in a trucking accident, other parties may also be at fault or share in the fault of a truck accident.
Those who can be held liable in a truck accident include:
- Loading company: When a truck accident occurs because the rig’s load was not properly loaded, the loading company or the owner of the freight being transported can be held liable for the victim’s injuries.
- Truck manufacturer: If an accident occurred as a result of a faulty part inside the truck, the vehicle manufacturer can be held liable. However, know that only about 5% of truck accidents are caused by equipment failure, most commonly brake or tire failure.
- Mechanic or inspector: A badly maintained truck can malfunction on the road and cause a truck accident. When a large truck undergoes inspection or routine maintenance, we hope the mechanic or inspector has done their due diligence by carefully reviewing the truck. However, defective trucks or unsafe rigs continue to be a problem in truck accidents.
Other third parties can be held liable in a trucking accident, including other passenger vehicles, the government agency in charge of the care of roadways, etc. An experienced truck accident attorney at Munley Law Personal Injury Attorneys can identify all sources of recovery so that you get the full amount of compensation you deserve.

Frequently Asked Questions About Liability in Philadelphia Truck Accident Cases
How Long Do I Have to File a Truck Accident Claim in Philadelphia?
In Pennsylvania, the statute of limitations for personal injury claims is generally two years from the date of the accident. However, certain factors, like claims involving government entities, may shorten deadlines. While two years may seem like a long time, it’s advised to consult an attorney as soon as possible if you wish to file a claim, as they will need time to conduct a thorough investigation and preserve evidence before it disappears.
What Evidence Is Most Important When Determining Liability in a Truck Accident Case?
Critical evidence includes driver logs, black box data, maintenance records, dashcam footage, and witness statements. Trucking companies often control key evidence, which makes early legal intervention essential. Attorneys can send spoliation letters to preserve this data. Strong evidence is the foundation of proving liability.
Why Are Truck Accident Claims Different from Car Accident Claims?
Truck accident claims are significantly more complex due to federal regulations, multiple liable parties, and higher insurance policies. These cases often involve corporate defendants and aggressive legal teams. They also require specialized knowledge of trucking laws. This makes experienced legal representation crucial.
What Role Do Federal Trucking Regulations Play in My Case?
Federal regulations set out by the FMCSA govern driver hours, maintenance, and safety standards. Violations of these rules can serve as strong evidence of negligence. For example, exceeding hours-of-service limits can indicate driver fatigue. Attorneys often use these violations to strengthen claims.
Do Truck Accident Cases Usually Go to Trial?
Many cases settle before trial, but some require litigation to achieve fair compensation. Law firms with trial experience often secure better settlements because insurers know they are prepared to go to court. Trial readiness can significantly impact outcomes, but your attorney will advise the best course.
How Much Does It Cost to Hire a Truck Accident Lawyer?
Most truck accident lawyers, including Munley Law, work on a contingency fee basis. This means you pay nothing up front and only owe fees if your case is successful. This structure allows victims to access high-quality legal representation without financial risk. Additionally, Munley Law offers free initial consultations.
