The Center for Health and Safety Culture at Montana State University conducted a comparative case study to better understand law enforcement’s attitudes and beliefs about traffic safety. This research project was part of the Traffic Safety Culture Transportation Pooled Fund and examined the differences between agencies in two rural and two urban states. The researchers conducted both qualitative and quantitative analysis to provide a deeper understanding of the cases involved. The project findings were based on the analysis of self-reported responses to a survey and augmented by interviews of law enforcement leaders. The Center made recommendations about methods to increase engagement in traffic safety efforts based on beliefs identified in the study.
