This report is an evaluation of restraint system benefits based on lap belt and shoulder harness usage rates and injury reduction benefits for all seating positions in North Carolina accident-involved vehicles. The restraint system data were collected in addition to the accident information normally collected by the North Carolina State Highway Patrol in the summer of 1970. Detailed analyses were conducted based on accident type, impact site, estimated speed just prior to contact, and non-belted and belted frequencies for both serious and minor injuries. Depending on the available sample sizes, chi-square, Poisson, or binomial tests were employed to detect significant differences between the belted and unbelted groups. The results, according to the authors, further document previous findings which show the effectiveness of lap belts and shoulder harnesses and point out the continuing need for programs aimed at increasing restraint system usage rates. /Author/
