In addition, only 55 percent of parents report using the upper tether, which provides additional attachment of the child safety seat to the vehicle and has been shown to reduce forward movement of the child's head, minimizing risk of head impact.

To help raise awareness of the LATCH system, NHTSA and the Advertising Council have created a series of public service announcements that are designed to raise awareness among all parents and caregivers about the importance of securing their children properly in their car seats.

"Informed parents and caregivers are the first line of defense for our youngest passengers traveling on our nation's roads," said NHTSA Acting Administrator David Kelly. "LATCH is an effective way to keep children restrained in a vehicle and safe in the event of a crash."

Protecting a child means making sure that his or her car seat is installed properly.

The LATCH System makes it easier to correctly install car seats.
