Missouri continues to lag behind the national average for seat belt use.
The Department of Transportation says seat belt use has remained stagnant at 79 percent compared to the nationwide average of 85 percent. Use among Missouri teens increased by a single percentage point from 66 percent to 67 percent.
Officials say 62 percent of the more than 600 roadway deaths this year were not wearing a seat belt.
Missouri law officers will be participating Monday in a statewide enforcement effort focused on seat belts and child restraints.
