KANAWHA CITY, W.Va. (WSAZ) -- If you've got small children, you know you need a car seat.
But police say you probably don't know how to use it.
"It needs to be good and tight, and it shouldn't be able to move more than one inch side to side," Trooper L.J. McClung said.
Several West Virginia State Police troopers, St. Albans Police officers, and Ashland Police officers were certified Friday by the Governor's Highway Safety Program to check seats.
Now, they're taking their knowledge on the road to make sure all kids are buckled in properly.
Out of seven car seats inspected Friday morning in Kanawha City, police say none were installed correctly.
The biggest problems dealt with positioning.
"One seat was positioned in the middle, but that doesn't have the proper anchors," McClung said.
Police say seats for children younger than two should face backward.
They also say all car seats have an expiration date stamped on them that should be heeded.
Trish Lusk says the knowledge gives her a chance to make some changes.
"I wouldn't just let my son sit in a car without being strapped in," she said. "He's my whole world."
State Police say regulations differ for each individual car seat, so they encourage you to bring yours down to your nearest detachment to get checked.
If your child is caught without a car seat, troopers you could end up paying about $200.
