An Act relative to leaving the scene of a collision

This bill amends Massachusetts law to clarify when a driver must stop after a collision. It adds two specific scenarios requiring drivers to stop: (1) if they collide with or cause injury to any vehicle or property, and (2) if they cause injury to a person without resulting in death. The changes modify existing language in the statute to explicitly include these situations, replacing "shall" with clearer phrasing requiring action after knowing injury occurred. This directly affects drivers involved in collisions where property damage or non-fatal injuries happen, expanding the legal obligation to stop beyond cases involving death or property damage alone.
