The top federal highway safety official says 90 lives would be saved every year in Missouri if the state had a law that allowed arrests of people not wearing seat belts. Missouri law now allows motorists to be ticketed for not wearing seatbelts only if they are ticketed for something else, too. The Administrator of the National Highway Traffic Safety Administration, Jeff Runge, says a primary seat belt law would reduce injuries in Missouri traffic crashes by one-thousand. He says 73 percent of Missouri motorists buckled up last year. The national average is 79 percent.
