The last phase of the NHTSA-U.S. Coast Guard Driver Improvement Training and Evaluation Project is described. Begun in July 1970, the project had two basic objectives. The first was to determine whether or not driver training programs do, in fact, significantly reduce driver errors and accidents and improve overall driver efficiency. The second was to identify which training method--classroom and driving range training (Program 1), classroom-only training (Program 2), or range-only training (Program 3)--is most effective. The population studied was 3,226 young male adults between 17 and 25 years of age. The specific sample studied was United States Coast Guard recruits at the Coast Guard Training Center in Cape May, New Jersey. While pretest data revealed no significant differences between the experimental and control groups, analysis of the posttest data indicated that the experimental groups performed significantly better on the driver knowledge test and on the driving range test than the control groups. A followup analysis of posttraining driving records was also conducted. (NTIS)
