Every year, children die from heatstroke after being left in hot cars—even on days that don’t feel dangerously warm. A child’s body overheats three to five times faster than an adult’s, and within minutes, a car can become deadly.
Prevent child deaths in hot cars in California by never leaving a child unattended, even for a few minutes. Every year, children die from heatstroke after being left in vehicles—even on days that don’t feel dangerously warm—because a child’s body overheats three to five times faster than an adult’s. Within minutes, the inside of a car can become deadly.
In California, it is illegal to leave a child age six or younger alone in a vehicle, and parents and caregivers should always check the back seat before locking the car, place reminders like a phone or bag in the back seat, lock parked cars to stop children from entering, and use car-seat alarms or safety apps. If you see a child left alone in a car, call 911 immediately—quick action can save a life.
Tragic hot car deaths often occur due to:
Forgotten children when routines change
Quick errands that take longer than expected
Unsupervised play where children climb into cars
Sadly, California has been one of the states hardest hit by child hot car deaths. Despite awareness campaigns, these tragedies continue every year.
In fact, according to Kids and Cars, since 1990 more than 836 children in the U.S. have died from vehicular heatstroke, making it one of the leading causes of non-crash child fatalities.
Tragically, we continue to bear witness to hot car deaths here in California and throughout the country. Despite a concerted effort to raise awareness about the serious dangers of leaving children in hot cars, it still happens at an alarming rate. In fact, since 1990, 836 children have died from heatstroke after being accidentally left in cars. That makes it the second-most common cause of nontraffic child fatalities from vehicles, behind accidental backovers. These numbers indicate just what a serious problem.
California fact: Because the state has warm weather year-round, hot car deaths can occur in any season.
The last thing we want to hear is that another child has died of heatstroke due to being left in a hot car. The majority of these deaths occur when the adult forgets the child is in the back seat, but this too can be remedied. Here are a few tips for preventing hot car deaths:
California law makes it illegal to leave a child under 7 years old unattended in a vehicle without supervision from someone at least 12 years old.
California Vehicle Code §15620 prohibits leaving young children alone in cars if:
Conditions present a significant risk to the child’s health or safety, or
The car is left running or the child has access to the keys.
Additionally, California has a “Good Samaritan Law” (Civil Code §43.100) that protects individuals from civil liability if they break into a car in good faith to rescue a child in danger from heat.
Protecting children is everyone’s business! If you see an unattended child in a car and are concerned, you should immediately call 911.
If the child is unresponsive or is in pain, immediately:
If the child is responsive:
H.R.3593, The federal Hot Cars Act was introduced in the U.S. Senate in July 2019 to prevent heatstroke deaths in cars.
The Helping Overcome Trauma for Children Alone in Rear Seats (HOT CARS) Act was introduced to require automakers to include child safety alert systems in all new vehicles.
These systems would function like seatbelt reminders—using sounds and dashboard alerts when a child is detected in the back seat after the engine is turned off.
More information is available at Congress.gov.
The HOT CARS Act of 2019 would require the Transportation Department to mandate all new motor vehicles have a “child safety alert system.” This would work similarly to existing seat belt alerts, with flashing symbols and warning sounds in the driver’s line of sight by the speedometer.
The full name is the Helping Overcome Trauma for Children Alone in Rear Seats Act.
The House version [H.R. 2801] was introduced last June by Rep. Tim Ryan (D-OH13). The Senate version [S. 1666] was introduced last July by Sen. Richard Blumenthal (D-CT).
If your child was left in a hot car due to a caretaker’s negligence, you may have legal rights under California personal injury and child endangerment laws.
If your child has been left in a hot car, call 911 immediately. If you notice a child in the backseat of a vehicle that is unattended, stay present and wait for authorities. Use your best judgment in these situations.
