Definition: Vehicles heat up very quickly, and that heat can be fatal to young children. Children are at a higher risk than adults of dying from heatstroke in a vehicle because their bodies heat up three to five times faster than adults’ (NHTSA). Children who are too young to communicate or open car doors are at particularly high risk from heatstroke in a vehicle (NHTSA). It is never safe to leave a child or children alone in a vehicle.
