It's National Child Passenger Safety Week, and State Police in Erie are taking part.
They offered free car seat checks at Erie's Emergycare on Tuesday. Parents got their child's car seats inspected to make sure they're installed correctly, and if they weren't up to code, state police replaced them.
Tuesday, police noticed most seats came in aren't properly installed.
"It can be anything from just being too loose or the straps aren't right, or it might have a seat belt and latch system," said Trooper Steve Oler, Pennsylvania State Police. "So there's a lot of different variables."
State Police conduct car seat checks once a month.
