Filing a Lawsuit Against an Out-of-State Trucking Company in Pennsylvania Courts

If you are injured by an out-of-state commercial truck in Pennsylvania, you can typically sue the trucking company in PA courts. By registering to do business in the state, commercial carriers generally consent to local jurisdiction, allowing you to seek compensation right here at home.

When a massive commercial semi-truck collides with a passenger vehicle on the Pennsylvania Turnpike or I-80, the consequences are often devastating. For residents in cities like Philadelphia, Pittsburgh, and Allentown, the legal aftermath becomes incredibly complicated when they discover the truck that hit them is registered in Texas, Ohio, or Florida. Suing a trucking company located across the country might sound like a nightmare, but Pennsylvania law provides strong mechanisms to hold these interstate carriers accountable. This guide explains how jurisdiction works and the steps you need to take to file a lawsuit against an out-of-state motor carrier.

Establishing Jurisdiction over Out-of-State Motor Carriers

In legal terms, 'jurisdiction' simply means a court's power to hear your case and make a ruling against the defendant. You do not have to travel to the trucking company's home state to sue them. Under the Pennsylvania Long-Arm Statute, 42 Pa.C.S. § 5322, you can sue an out-of-state business if they caused harm within the Commonwealth. Furthermore, recent landmark decisions, such as Mallory v. Norfolk Southern Railway Co., 600 U.S. 122 (US Supreme Court 2023), have affirmed that if an out-of-state corporation registers to do business in Pennsylvania, they effectively consent to being sued in Pennsylvania courts. Since commercial trucking fleets operate widely across PA highways, establishing jurisdiction here is generally straightforward.

Federal vs. PA State Court Pros and Cons

When suing an out-of-state trucking company, you often have the choice to file in a Pennsylvania state court or a federal court. This happens because of a legal concept called 'diversity of citizenship,' which allows federal courts to hear cases where the plaintiff and defendant are from different states.

  • State Court: Filing in a local state court, like the Court of Common Pleas of Allegheny County, Pittsburgh or the Court of Common Pleas of Philadelphia County, Philadelphia, is often preferred by local lawyers. State courts can sometimes move slightly faster in the pre-trial phases, and juries in certain PA counties are historically more favorable to injured plaintiffs.
  • Federal Court: The trucking company's defense lawyers will often try to 'remove' the case to a federal court, such as the U.S. District Court for the Eastern District of Pennsylvania, Philadelphia or the U.S. District Court for the Middle District of Pennsylvania, Harrisburg. Federal courts follow strict scheduling orders and unanimous jury rules, which defense attorneys believe gives them a strategic advantage.

Serving a Summons to an Interstate Trucking Fleet

Before a lawsuit can begin, you must officially notify the trucking company that they are being sued. This is called 'serving process.' Because interstate trucking companies are heavily regulated, they are required by the Federal Motor Carrier Safety Administration (FMCSA) to designate a registered agent in every state where they operate. You do not need to track down the CEO in another state; your lawyer simply delivers the court documents, such as Form AO 440, Federal, U.S. District Court, Summons in a Civil Action, directly to their designated agent in Pennsylvania.

Applying PA's 51% Comparative Negligence Rule

A common defense tactic used by out-of-state trucking companies is to blame the local driver for the crash. They might claim you were speeding or merged improperly. Pennsylvania follows a modified comparative negligence system, specifically 42 Pa.C.S. § 7102. This means you can still recover financial compensation as long as you are not more than 50% responsible for the accident. However, your final payout will be reduced by your percentage of fault. If a jury finds you were 20% at fault and the truck driver was 80% at fault, a $100,000 award would be reduced to $80,000. If you are found to be 51% or more at fault, you get nothing.

How Much Does it Cost to Sue in PA?

Most truck accident attorneys work on a contingency fee basis. This means you pay nothing upfront, and the lawyer takes a percentage (usually 33% to 40%) of the final settlement or jury verdict. However, there are administrative costs to open a case. Filing a civil complaint in a PA Court of Common Pleas generally costs between $150 and $300, depending on the county. Federal court filing fees are typically around $400. Expert witnesses, such as accident reconstructionists needed to prove the truck driver's negligence, can cost thousands of dollars, though your law firm usually advances these costs.

How Long Does the Process Take?

Commercial trucking lawsuits are complex and rarely resolved overnight. If liability is clear and the trucking company's insurance is willing to offer a fair settlement, the process might take 9 to 18 months. However, if the out-of-state carrier fights the jurisdiction, disputes the fault, or drags out the discovery phase, litigating the case in a federal or state court can easily take 2 to 3 years before reaching a jury trial.

Frequently Asked Questions (FAQ)

What is a registered agent?

A registered agent is an individual or business authorized to receive official legal and tax documents on behalf of a company. Out-of-state trucking companies must have an agent in Pennsylvania so that injured citizens have a local address to serve lawsuits.

Does it matter if the truck driver lives in a different state than the trucking company?

Usually, no. Under a legal doctrine called 'respondeat superior', an employer is generally responsible for the negligent actions of their employees while they are on the job. You will typically sue the trucking company itself, regardless of where the driver lives.

Can I sue if the accident happened outside of PA, but I live here?

This is much more difficult. If the crash happened in Ohio, you generally must file the lawsuit in Ohio, even if you are a Pennsylvania resident. Jurisdiction is heavily tied to the physical location where the injury occurred.

Will I have to testify in a federal court?

If your case goes to trial, you will likely need to testify, whether it is in a state or federal court. However, the vast majority of commercial truck accident cases are settled out of court long before a trial takes place.
