The objectives of this research are to 1) design and implement formative research to identify teen social norms, attitudes, knowledge, and perceptions related to cannabis and driving, and evidence-based approaches and models to support parents and caregivers of teens; and 2) develop educational resources that support parents and caregivers in talking with teens about cannabis impaired driving. The project will develop educational resources to support parents and caregivers in talking with teens about cannabis impaired driving and impaired driving laws.

Research is needed to develop a better understanding of the relationship between enforcement and safety outcomes, and to show how changes in enforcement activity/investments may or may not affect safety outcomes. Quantifying the safety outcomes of traffic enforcement can potentially contribute to the body of knowledge regarding the efficacy of enforcement. Outcomes can also help to calibrate enforcement efforts, favoring those that are more promising for given driving behaviors and violations.

Child Passenger Safety (CPS) is one of the focus areas for State Highway Safety Offices (SHSOs) for which the opportunity exists to more effectively engage underserved populations in protecting children from motor vehicle crash fatalities and injuries. Repeated requests for best practices have yielded some materials, but there is no step-by-step resource to help stakeholders engage and retain participation by underserved communities.

The objective of this research is to characterize the current state of knowledge related to Advanced Driver Assistance Systems (ADAS), identify populations in need of education on the matter, and recommend methods of delivery for that education. 

Young drivers with developmental disabilities may be at increased risk for crashes due to impairments commonly associated these conditions.

The objective of this research is to evaluate the current state of practice for motorcycle licensing in the U.S. and develop recommendations for improvement based on the latest empirical data.

This research will assess the cost-effectiveness of alternative drug screening approaches, assess the costs & benefits associated with the collection of oral fluid at the roadside & inform traffic safety professionals about the costs & benefits associated with alternative DUID crash countermeasures.

The objective of this research is to re-define stakeholder engagement during the development of safety plans, interventions, programs, projects, and policies so outcomes focus on multi-solving decision-making and implementation.

Do teen drivers who are exposed to greater diversity of traffic and road environments early in their driving careers have lower crash involvement than those who are exposed to less diversity? This research project will attempt to answer that question.

This research project will develop guidelines for traffic safety messaging and explain how different demographic groups respond to different methods.
