Are you using this life-saving device for your child’s car seat?

MATTHEWS, NC (WBTV) - Most parents who install their child's car seats themselves are misusing the tether strap which can be a life saving device. This is according to a new study released by child safety organization, Safe Kids Worldwide.

Safe Kids Worldwide conducted the study between October 2015 and December 2016.

Tim Aycock, with the Matthews Police Department, said his department participated in the study during it's weekly car sear check, one of the only weekly checks in the Charlotte-area.

Last year, Aycock said his department checked about 1,200 car seats, making sure they were installed properly.

"I think most parents, they want their baby to be comfortable and they worry about their comfort… that's the biggest mistake or issue that we see," Aycock said.

Aycock said during the study, officers asked parents and guardians whether they knew what the tether strap was and what is was used for.

"Probably 90 percent of them didn't know," Aycock said.

The device is a tether located on the ceiling, rear shelf, or back of the vehicle seat

According to Safe Kids and Aycock, using the tether properly is simple. All you need to do is locate the strap, attach the car seat hook to the strap, and then tighten it.

Aycock said even though using the strap is simple, it can save a child's life.
