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.

NHTSA’s recently published reports are listed chronologically below. To the right are additional resources including Behavioral Research Notes and Traffic Techs. The most recent Behavioral Research Note is dated October 2017. The most recent Traffic Tech is dated September 2017.
