| Analysis of Speeding-Related Crashes |
| Speeding is one of the most common contributing factors of traffic crashes. Data extracted from the Fatality Analysis Reporting System (FARS) show that the driver-level attribute “driving too fast for conditions or in excess of posted speed limit” is the critical contributing factor in more than 99 percent of all speeding-related fatal crashes, as defined by the National Highway Traffic Safety Administration (NHTSA). A marginal number of drivers were determined to be speeding through citations of speeding violations reported to FARS. To read the entire report, click on the link below. |

| Review of State Motorcycle Safety Program Technical Assessments |
| A key effort initiated by NHTSA, aimed at promoting motorcycle safety and understanding the factors that contribute to motorcycle crashes, is the State Motorcycle Safety Program Technical Assessments ("State Assessments"), which provide comprehensive reviews of State motorcycle safety programs and practices. During the assessments, reviewers examine the policies States have implemented to promote motorcycle safety and offer recommendations for additional steps States may take to encourage safe riding and reduce crashes, injuries, and fatalities. |
