A study conducted at San Francisco State says almost 600 children have died since 1998 as a result of being left in their caregivers hot cars.
Research shows that on average 37 kids die from being left in the cars every year, so far in 2013, 15 kids have died.
The study says of those near 600 deaths, only 18 percent were the result of parents purposely leaving their kids in cars.
The were accidental, with 52 percent of the parents simply forgetting their children were in the back seat.
The numbers show a sharp increase in those deaths following the creation of passenger-side airbags, and children having to move in the back seats.
Local fire fighters say one tip parents can use to avoid forgetting their kids in the car is to put an important object in the back seat of the car like your cell phone, purse or briefcase.
