Since 1998, more than 700 children have died in vehicles from heat stroke in the USA.
More than 70% of heat stroke deaths occur in children younger than age 2.
More than half of heat stroke deaths occur because a caregiver forgot the child in the car.
Roughly 30% of heat stroke deaths occur because the child got in the car without a caregiver knowing and couldn't get out.
Nearly 20% of deaths occur because a caregiver intentionally left the child in the car.
