"I'm fine to drive" is a choice that ruins lives in a split second. 🍺❌

As back-to-school season starts, daily routines change fast — drop-offs, new routes and busy mornings. Routine changes are the #1 cause for kids forgotten in a hot car.

Make these habits automatic:
⚫ Place an important item in the back seat.
⚫ Once You Park, Stop. Look. Lock.
⚫ Keep your car locked and keys out of a child's reach.
