The proposed legislation, known as the Bernard N. Gribbin Law, amends Title 75 of the Pennsylvania Consolidated Statutes to introduce a new section addressing the offense of interference with the operation or movement of public transit vehicles. The bill defines various actions that constitute this offense, including attempts to cause serious bodily injury or death to an operator, causing bodily injury to an operator, and intentionally interfering with an operator's duties that result in injury to others. The law categorizes these offenses into different degrees of felonies and misdemeanors based on the severity of the actions.

Specifically, a violation that results in serious bodily injury or death to an operator is classified as a felony of the first degree, while other violations that cause bodily injury or involve threats of serious harm are classified as felonies of the third degree or misdemeanors of the second degree. The bill also provides definitions for key terms such as "operator" and "public transit vehicle" to clarify the scope of the law. The act is set to take effect 60 days after its passage.
