## TLDR

- A car can heat about 20°F in 10 minutes; most hot-car deaths happen when a loving caregiver forgets after a routine change.
- Look before you lock: put your phone or bag in the back seat, and ask childcare to call if your child doesn't arrive.
- Walk around the car before moving it, keep cars locked, and all kids under 13 ride in the back. See a child alone in a hot car? Call 911.

## Hot cars: why it happens

- A car's inside temperature can rise about 20°F (11°C) in 10 minutes, even on a mild day with
  windows cracked. Children heat up much faster than adults.
- Most hot-car deaths happen when a loving, capable caregiver forgets a child is in the car,
  usually after a change in routine: a different parent doing drop-off, a skipped stop, a new job.
  Memory works this way for everyone; plan for it.
- About a quarter of cases involve children who got into an unlocked car on their own.

## Habits that prevent it

- **Look before you lock:** open the back door every time you park.
- Put something you need, like your phone, bag or work badge, in the back seat.
- Ask your childcare provider to call you if your child hasn't arrived by a set time.
- Talk through drop-off changes out loud with partners, co-parents and grandparents.
- Never leave a child alone in a car, even for a quick errand, with the engine running or not.
- Lock cars at home, keep keys and fobs out of reach, and check cars and trunks first if a child
  goes missing.

## Driveways and parking lots

- Small children are hard to see behind or in front of a vehicle, even with cameras.
- Walk around the car before you move it, and know where every child is. Have kids stand by the
  door with a hand on the car, or hold an adult's hand, during loading.
- Don't let driveways become play areas.

## Inside the car

- All children under 13 ride in the back seat. See the car seats guide for seats and boosters.
- Secure loose items such as bags, groceries and water bottles; they fly forward in a crash.
- Power windows can trap fingers and necks; use the window lock.
- Use child locks on rear doors, and never let children play in a parked car.
- Car seats are for travel. Once you arrive, take a sleeping baby out to a flat, firm sleep space.
- Never ride with a child on your lap, and no children in truck beds or cargo areas.
- Rideshares and taxis: bring your child's seat.

## Long trips and summer days

- Plan stops every 2 hours or so. Kids need breaks, and so do drivers.
- Check seat surfaces and buckles before buckling in; metal can burn skin in the sun.
- Sunshades on side windows help, but secure them so they don't become projectiles.

## When to check in

- Ask your childcare center about its late-arrival call policy at enrollment.
- If someone in your home is often worn out, talk together about adding reminder systems.
- If you see a child alone in a car, especially on a warm day, call 911.
