This study is sponsored by the AAA Foundation for Traffic Safety (AAFTS). NORC will assess and document current state-level policies and practices in all 50 states and DC as they relate to drugged driving. The project team will initiate a literature review process by conducting a Westlaw computer-assisted legal search to identify state legal records. This will be followed by four additional searches: 1) identifying in-state literature and policies directly from state highway safety offices, 2) reviewing documents from the state department of transportation agencies, 3) searching websites and documents from each state police agency, and finally identifying any court level documents relating to drugged driving. Once these steps have been completed, NORC will synthesize and document the findings by comparing information ascertained from the search with the state-level recommendations documented by the AAAFTS drugged driving expert panel.
