abstract="A statistical association is found between the number of traffic citations for belt law violations versus observed belt use. Also, belt use is higher in primary enforcement states where officers issue such citations for belt law violations alone. In secondary enforcement states officers issue such citations only after stopping motorists for another reason. Most belt laws provide for secondary enforcement. Enforcement data were confined to the highway patrol in each state (local arrest data are rarely compiled statewide). Belt use data were based on observational surveys conducted in each belt law state.<p />",
