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.
Evaluation of the NHTSA Distracted Driving High-Visibility Enforcement Demonstration Projects in California and Delaware
It was concluded that high-visibility enforcement can be implemented over widespread, multi-jurisdictional areas and may reduce the number of people who use handheld cell phones while driving.
Evaluation of Washington State Target Zero Teams Project
As part of its "Target Zero" strategic highway safety plan that has the goal to reduce traffic fatalities in Washington to zero by the year 2030, the State of Washington established three detachments of Washington State Patrol (WSP) troopers to focus on nighttime impaired-driving offenses.
Process Overview of the High-Visibility Enforcement Programs Targeting Handheld Device Users in California and Delaware
The information in this process report includes: (1) how to plan and implement a regional/statewide HVE program that targets phone use while driving; (2) distracted driving enforcement practices; and (3) lessons learned from the California and Delaware distracted driving demonstration programs.
Evaluation of a High-Visibility Enforcement Seat Belt Program on the Blue Ridge Parkway
The National Park Service implemented a high-visibility seat belt enforcement program on the Blue Ridge Parkway (BRP), involving low-cost media and strong enforcement partnerships, activity associated with significant increases in observed seat belt use on the BRP.
BAC and Crash Responsibility of Injured Older Drivers: An Analysis of Trauma Center Data
This study examined the distribution of blood alcohol concentrations (BACs) in injured drivers 65 and older and the relationship of older-driver BAC to driving record and crash responsibility.
Ignition Interlock: An Investigation Into Rural Arizona Judges' Perceptions
This study sought to answer several questions regarding 2007 Arizona legislation requiring ignition interlock for all offenders convicted of Driving-Under-the-Influence (DUI), including first time DUI offenders. At the time the law was passed, Arizona was only one of two States [New Mexico being the other] to require ignition interlock for first time offenders.
Investigation of the Use and Feasibility of Speed Warning Systems
This report summarizes a feasibility evaluation of a speed monitoring system that provided speed warning feedback to drivers enrolled in a voluntary program, with particular emphasis on at-risk drivers, especially chronic speeders.
Speed Management Program Plan
The goal of this Speed Management Program Plan is to improve public health and safety by reducing speeding-related fatalities and injuries.
Evaluation of NHTSA Distracted Driving Demonstration Projects in Connecticut and New York
The communities of Hartford, Connecticut, and Syracuse, New York, implemented year-long campaigns to test whether NHTSA's high-visibility enforcement (HVE) model could be applied to reduce two specific forms of distracted driving – driving while talking on a hand-held cell phone or texting.
Demonstration of the "Trauma Nurses Talk Tough" Seat Belt Diversion Program in North Carolina
The results of this study support the combination of high-visibility enforcement and a diversion classroom-based brief intervention as a means of increasing seat belt use in a predominately rural, low-belt-use area.
