Trucking Industry and Legal Industry Terms You May Hear During Your Trial


Going through a trucking injury lawsuit is a challenging, emotionally draining experience for most accident victims. During the lawsuit the victim is often forced to relive the experience. Further adding to this already difficult experience is the fact that the victim will often encounter an abundance of unfamiliar, confusing terms. Both the trucking industry and the legal industry each have their own special lexicon that the average person may never have experienced.


During your case you will probably hear many legal terms. Some may be familiar to you or be terms whose meaning you can readily deduce, while others may be completely unfamiliar and incomprehensible. Your attorney will be able to further explain these and other legal terms and their relevance to you.

Admissible – The term “admissible” is usually applied to whether or not a particular piece of evidence will be allowed to be considered in the case. Not all information is automatically admissible because it may not be pertinent to the case, may not have been obtained legally from a reputable source, or may unfairly create a bias.

Alleged – Until something is proven it is considered “alleged.”

Contract – A “contract” is a legal agreement between two or more parties that is legally enforceable. Types of contracts vary and may be signed and in writing, or they may be verbal.

Damages – The term “damages” refers to the compensation awarded by the court to the wronged party.

Defendant – The “defendant” is the party being sued. In a trucking injury case the trucker and/or trucking company is the defendant.

Discovery – “Discovery” refers to the pretrial phase during which evidence that will be used during the trial is made known to each party.

Doctrine of Respondeat Superior – The Doctrine of Respondeat Superior is commonly used during trucking accident cases. This doctrine applies when truckers are acting within the course and scope of their employment and the trucking company is held liable for the actions of its truck driver. In this way a trucking company can be sued for the actions of a trucker.

Liable – A party is held “liable” when they are determined to be legally responsible for something in a civil case.

Proximate Cause – The “proximate cause” is an event that is sufficiently related to the accident or injury such that it can be determined the cause of that accident or injury.


During your trucking accident case a number of different governmental departments and agencies might be referenced. This is often done to refer to specific regulations or guidelines that these agencies have established. Some of the most commonly referred to departments and agencies for trucking cases include:

Federal Motor Carrier Safety Administration (FMCSA) – The Federal Motor Carrier Safety Administration, or FMCSA, is an administration within the Department of Transportation (DOT).

During the course of your trucking accident trial you will likely hear some specific terms that relate to the trucking industry.
