This project tests bystander interventions to determine their effectiveness and inform development of new interventions for school-age children.
This project collects self-reported data about over-the-counter, prescription and illegal drug use, and biological samples to detect the presence of these drugs among drivers arrested for DUI and/or DUID.
This project seeks to assess features in an Interlock Enhancement Counseling program by comparing treatment and control groups.
This project explores the effects of modules to train novice drivers in (1) hazard identification and (2) the risks associated with using electronic devices while driving on their subsequent crash and citation rates. The original study sites withdrew due to COVID-19. NHTSA is requesting new study sites and expects data collection to begin in 2021.
This project seeks to identify the major data sources of drug-impaired driving information by listing the various sources of data on drug use and drugged driving and noting the strengths and weaknesses of each.
This project synthesizes various studies evaluating the effectiveness of speed feedback signs to reduce speeding and speeding-related crashes.
This project examines why riders choose to wear — or not wear — high-visibility gear. Through a focus group of motorcycle riders, the report finds that while most participants did not regularly wear such gear, those who did reported doing so after having been in a crash with a motor vehicle, or personally knowing another rider who had been in such a crash.
This project seeks to determine the use of on-site oral fluid testing devices in the U.S. and abroad, scan agency protocols and examine legal issues regarding their use.
This project examines existing risk communication strategies for impaired and distracted driving, reviewing messages and materials, theories and models of behavior change, risk communication, and communication theory and how these are relevant to impaired and distracted driving.
This project focuses on risk communications for seat belt safety, consisting of a literature review of theories of behavior change and communications theory and their relevance to vehicle occupant protection as well as review and catalog existing messages.
This project provides an inventory of state-managed interlock programs, lists their key program elements and discusses how states manage their ignition interlock device data. Recruitment and data collection for this project were delayed due to COVID-19.
This project conducts a scan of LEL programs across the states including position descriptions, program objectives, reporting requirements and performance strategies. The Phase 1 final report is under review, with optional task planning underway.
This project involves developing a white paper summarizing research on the connection between THC use and driving performance and the likelihood of increased crash risk as well as the impact of marijuana per se limits and laws.
This project performs a meta-analysis to evaluate the tools law enforcement agencies and partners use to assess the level of enforcement needed to have a deterrence effect in their communities.
