Sevierville police took to social media this week with a blunt reminder that stunned even some longtime locals: federal data show 31 children have already died in 2025 after being left in, or climbing into, hot vehicles. Their Facebook warning tracked closely with national safety campaigns and stressed that a parked car can turn deadly in minutes, especially for infants and toddlers whose bodies heat up far faster than adults. The department urged drivers to build a habit of checking the back seat every time they park, to lock vehicles, and to keep keys where curious kids cannot get them.
Federal officials have been sounding the alarm for years, and the numbers behind this latest warning are grim. According to NHTSA, 31 children died from vehicular heatstroke in 2025, and the agency reports that a vehicle can heat up by about 20°F in roughly 10 minutes. NHTSA also notes that “even on days as cool as 60 degrees, a child can die in a hot car,” and that more than 1,000 children have lost their lives this way since 1998.
How many children are affected?
The exact count shifts slightly depending on who is tracking the cases, since each group compiles reports from news coverage and public records, but the overall picture is chillingly consistent. The Jan Null NoHeatStroke database lists 32 pediatric vehicular heatstroke deaths for 2025, while nonprofit trackers maintain detailed incident lists. For ongoing, case-by-case documentation, NoHeatStroke and Kids and Car Safety both show that the majority of victims are infants and toddlers and that more than a thousand children have died in hot cars since the late 1990s.
Why vehicles become deadly so fast
Children’s bodies heat up three to five times faster than adults, which leaves very little margin for error when a child is stuck in a sweltering vehicle. Inside temperatures can spike quickly even when it does not feel particularly hot outside. Federal safety materials point out that cracking a window or parking in the shade does little to reduce the danger, since cabin temperatures can still climb tens of degrees within minutes. The federal campaign site Traffic Safety Marketing notes that heatstroke can occur when outdoor temperatures are as low as 60°F.
What officials recommend
Safety officials say that straightforward, repeatable routines are what save lives: check the back seat every single time you park, no matter how short the trip, lock the car, and keep keys and fobs out of reach of children. The federal Stop. Look. Lock. campaign and local safety offices also urge bystanders to call 911 immediately if they see a child alone in a vehicle. Sevierville police echoed that advice in their Facebook message, tailoring the reminders to local caregivers.
When these tragedies become criminal cases, the legal outcomes vary widely by state and circumstance. Some incidents result in child endangerment or homicide charges, while others do not lead to prosecution. National outlets and advocacy organizations keep running tallies of cases and court decisions for researchers and policymakers; recent coverage by ABC News highlights how those investigations can unfold.
