As temperatures rise going into spring and summer, so does the risk of vehicular hyperthermia for children left inside hot vehicles. Each year since 1998 an average of 38 children have died in hot cars in the U.S. Although these tragedies occur nationally, California is one of only 20 states that has addressed the issue formally. The law in California (Kaitlyn’s Law) holds that leaving a child unsupervised in a motor vehicle is a violation with a fine of one hundred dollars (CAL. VEH. CODE 15620).
(a) A parent, legal guardian, or other person responsible for a child who is 6 years of age or younger may not leave that child inside a motor vehicle without being subject to the supervision of a person who is 12 years of age or older, under either of the following circumstances:
(1) Where there are conditions that present a significant risk to the child’s health or safety.
(2) When the vehicle’s engine is running or the vehicle’s keys are in the ignition, or both.
