Behaviors and Attitudes
NHTSA studies behaviors and attitudes in highway safety, focusing on drivers, passengers, pedestrians, and motorcyclists. We identify and measure behaviors involved in crashes or associated with injuries, and develop and refine countermeasures to deter unsafe behaviors and promote safe alternatives.
Our recently published reports and research notes are listed chronologically below. To the right are additional resources including Traffic Techs.

Breath Test Refusal Rates in the United States – 2011 UpdateBreath alcohol concentration (BAC) test refusals by suspect- ed impaired drivers are a challenge for impaired driving enforcement and prosecution. Periodically, NHTSA gathers data on State BAC refusal rates and develops an estimated national rate. This information can be useful to States and local jurisdictions. It enables them to track changes over time and compare their rates to other States and the Nation as a whole. NHTSA developed previous estimates for 1987, 2001, and 2005. |
