DES MOINES, Iowa — Traffic safety officials say seat belt use in Iowa has risen to 93 percent from about 18 percent in 1985, the year before the state's seat belt law took effect.
In September 1986, only 46 percent of Iowans followed the newly implemented law. The figure rose to 61 percent by 1990 and to 78 percent by 2000.
Mark Nagel with the Governor's Traffic Safety Bureau says 2011's average figure of 93 percent across Iowa is about 9 percentage points higher than one survey's national average.
Failing to buckle up in Iowa is a "primary" violation for which an officer can pull over a vehicle.
