The bill establishes legal protections for individuals who rescue vulnerable persons or domestic animals from locked motor vehicles. It introduces definitions for "domestic animal," "motor vehicle," and "vulnerable person," clarifying that a domestic animal refers to pets like dogs and cats, while a vulnerable person includes minors and individuals with disabilities or impairments.

Additionally, the bill provides immunity from civil liability for any damage caused to a motor vehicle during the rescue, provided that the rescuer meets specific conditions. These conditions include confirming that the vehicle is locked, having a reasonable belief that the individual or animal is in imminent danger, notifying law enforcement or calling 911 prior to entry, using only necessary force to gain access, and remaining with the rescued individual or animal until help arrives.
