NORTH DAKOTA SELECTIVE TRAFFIC ENFORCEMENT PROGRAM (STEP). FINAL EVALUATION

The report presents an evaluation of the North Dakota Selective Traffic Enforcement Program. Five experiments in two counties were evaluated. It was found that the STEP activities of live patrol and conspicuous observation in Grand Forks County were associated with significant reductions in accidents and injuries during a time when these parameters were increasing in the rest of the State. In Cass county it was found that radar speed enforcement combined with a public information campaign was associated with a dramatic increase in compliance with the speed limit. Portable pre-arrest breath testers were given by enforcement officers assigned to experimental groups and their records were compared to officers assigned control groups. The officers with the device made significantly more arrests with significantly lower BAC's than those without. A special speed enforcement study yielded inconclusive results due to speed recording equipment problems resulting in inadequate data.
