There are, however, several stipulations. A "Good Samaritan" would be protect from liability if he/she:
found the vehicle locked “or there is otherwise no reasonable method for the child to exit” the vehicle;
has “a good-faith belief” that forcible entry “is necessary because the child is in imminent danger of suffering harm if not immediately removed” from the vehicle, and, “based upon the circumstances … the belief is a reasonable one”;
contacts the local law-enforcement agency, the fire department or the 911 emergency telephone service prior to breaking into the vehicle;
leaves a notice on the vehicle’s windshield “with the person’s contact information, the reason entry was made, the location of the child,” and word that authorities have been notified;
remains with the child “in a safe location, out of the elements but reasonably close to the motor vehicle,” until the police or sheriff’s department, fire department or some other emergency responder arrives;
exercised “no more force … than necessary under the circumstances” to enter the vehicle and remove the child.
