The latest annual seat belt survey shows Iowa’s not losing –or gaining– any ground in buckling up.The Iowa Department of Transportation survey found no fluctuation in the survey, according to D-O-T traffic safety specialist Scott Falb. Seventy-eight-percent of Iowans wore their seat belts last year. That’s the same number as the year before and just one-percent higher than in 1998. It’s one of the highest rates in the nation. Falb says the people who -don’t- buckle up tend to be poor, rural or elderly people or those who often ignore traffic laws.Falb says younger Iowans tend to wear their seat belts more often, probably since they’ve known little else. The state law was enacted in 1986.
