A widely shared figure, 31 children, is being used by local officials to hammer home a grim national problem: pediatric vehicular heatstroke. The Blount County Sheriff's Office posted a warning on Friday, urging residents to lock cars and keep keys out of children's reach, stressing that an enclosed vehicle can become deadly even on a cool day. Safety officials say the boring stuff is what saves lives: a quick back-seat check, locked doors every time, and asking childcare providers to call if a child does not arrive as expected.
In a Facebook post, the sheriff's office cited the 31-death figure and reminded caregivers that children can climb into unlocked vehicles and become trapped, according to the Blount County Sheriff's Office. The post also pointed followers to federal resources on vehicular heatstroke and urged vigilance as warmer weather approaches.
Who is keeping the count
NoHeatStroke.org, the long-running tracker maintained by Jan Null at San Jose State, updated its tally on May 21 and lists 32 pediatric vehicular heatstroke deaths for 2025 and more than 1,000 deaths since 1998. The site's analysis shows most fatalities involve a child forgotten by a caregiver, with "gained access" and "knowingly left" comprising the bulk of the remainder, per NoHeatStroke.org.
How quickly a car becomes deadly
Federal safety officials note that a vehicle's interior can rise roughly 20°F in about 10 minutes and that a child’s body temperature increases three to five times faster than an adult’s, making even short periods alone in a car dangerous. The National Highway Traffic Safety Administration has warned that lethal internal conditions can occur on days as cool as 60°F and packages these warnings under its Stop. Look. Lock. campaign, per NHTSA.
Prevention steps officials recommend
State highway-safety offices and federal partners emphasize a few simple, repeatable steps: check the back seat every time you exit, never leave a child unattended even for a minute, and always lock vehicles and store keys out of children’s reach. Those talking points and ready-made outreach materials are available through federal traffic-safety toolkits and campaign pages, per Traffic Safety Marketing.
Local context and legal outcomes
Local agencies like the Blount County Sheriff's Office are amplifying those warnings as summer nears; in other jurisdictions, investigations into hot-car deaths have sometimes led to criminal child-endangerment prosecutions. A recent Los Angeles case that resulted in a no-contest plea is detailed in coverage by View Park no-contest plea, illustrating how outcomes vary by circumstance and state law.
Officials emphasize that these deaths are largely preventable: neighbors, caregivers, and childcare providers all have roles to play. If you see a child alone in a vehicle, call 911 immediately and follow local emergency guidance; federal and state pages linked above offer print-and-share materials for families and community groups.
