Seat Belt Use in North Dakota

The purpose of North Dakota’s seat belt use study is to provide statistically reliable data from which generalizations, comparative analyses and recommendations can be developed. The sampling methodology for this study was originally developed in 2001 with guidance from National Highway Transportation Safety Administration (NHTSA) and it has remained stable since then, with relatively no change in the counties and sites that make up the sample. The 2011 survey was based on a random probability sample of 16 North Dakota counties and 319 observation sites developed for and approved by NHTSA in 2001. Trained observers used the week of June 6-10 to visit each site in their assigned county and collect the seat belt use data as prescribed in the handbook they received at training. Front seat drivers and outboard passengers in automobiles, vans, sport utility vehicles (SUVs), and pickup trucks were observed for seat belt use. Observation data forms from each site were submitted for entry and analysis. For the 2011 statewide survey, observers tracked seat belt use for 16,390 drivers and 4,104 outboard passengers, for a total of 20,494 vehicle occupants. The estimates of seat belt use were 71.4% for drivers, 75.9% for passengers, and an overall unweighted estimate of 72.3% belted for drivers and passengers combined. This result compares to the unweighted rate of 69.8% belted in 2010. In general, the findings in the 2011 North Dakota statewide survey are consistent with the findings of previous surveys. The weighted state rate for 2011 is 76.7% compared to 74.8% for 2010.
