input: [Action Item Number] 1.5.B [Action Item Name] Collect Further Data on Drugged Driving [Lead Agency] ONDCP [Component(s)] --- [Action Item Description] 
output: Much greater efforts are required by Federal and local agencies to focus on the serious drugged driving threat, but these efforts must be built on a strong foundation of accurate data. Read more Data sources to track drugged driving among the overall population include SAMHSA’s National Survey on Drug Use and Health and NHTSA’s National Roadside Survey of Alcohol and Drug Use by Drivers. In addition, NHTSA’s Drug Evaluation and Classification program captures information on drug evaluations conducted on drivers arrested on suspicion of impaired driving. Further, the Fatality Analysis Reporting System, known as FARS, provides testing results for drivers in fatal car crashes. FARS data on drug use for 80 percent or more of all fatally injured drivers is available for 15 states. The National Roadside Survey of Alcohol and Drug Use by Drivers is the only survey of non-crash-involved drivers using a specific biomarker (generally a blood or saliva test) that confirms the presence of drugs in those who volunteer to participate in the survey. NHTSA has conducted the National Roadside Survey on a 10-year cycle, most recently in 2007. The Survey estimates the use of alcohol and other potentially impairing drugs by drivers. Federal drug control agencies will reduce the length of time between National Roadside Surveys as one measure of progress on drugged driving.
