Abstract:This dataset supports the conclusions of the 2013–2014 National Roadside Study of Alcohol and Drug Use by Drivers. The three report volumes -- Methodology, Drug Results, and Alcohol Results -- are available in this repository and linked to this record.
This dataset records results from 11322 roadside surveys conducted across the United States in 2013 and 2014, as described in the Methodology volume. When possible, oral fluid and blood samples were taken and were subjected to laboratory screening and liquid chromatography-mass spectrometry (LC/MS/MS; the term MS/MS is the combination of two mass analyzers in one mass spec instrument) and gas chromatography-mass spectrometry (GC/MS) confirmation respectively for alcohol and six classes of drugs, allowing researchers to estimate a national prevalence of alcohol and other drugs in drivers. The dataset also includes information from a self-administered questionnaire, also described in the Methodology document. All drivers’ responses were completely voluntary and anonymous. Re-identification risk of study participants from this dataset is very low.
The data files are collected into a single ZIP file, with a total size of 54 MB.
