Did you know when it’s 80 degrees outside, the temperature inside a vehicle can reach deadly levels in only 10 minutes—even with a window rolled down a couple of inches? As the thermometer soars this summer, summer vehicle safety for children is once again top of mind for all parents and caregivers.

Children overheat more easily than adults, and infants and children under 4 are at greatest risk. Accidents can happen to even the most conscientious parents and caregivers, so the U.S. Department of Transportation’s National Highway Transportation Safety Administration (NHTSA) and Safe Kids are now working to increase awareness the dangers of heatstroke.

In the “Where’s baby? Look before you lock.” Campaign, NHTSA and Safe Kids recommend the following precautions to help you prevent a heatstroke tragedy:

1. Never leave a child unattended in a vehicle. Period.
2. Make a habit of checking front and back seats before locking your vehicle and walking away.
3. Ask your childcare provider to call if your child is absent.
4. Do things that remind you a child is in the vehicle, like putting your purse or briefcase in the back seat.
5. Keep your vehicle locked when not in use, and always store keys out of your child’s reach.

When you’re out and about, if you ever see a child alone in a hot vehicle, immediately call 911—every minute counts.
