National Roadside Surveys (NRSs) are a
central tool in understanding alcohol- and drug-involved driving.
Starting in 1973, roadside surveys of drivers on the road have
estimated the population-level prevalence of drinking and driving
in the United States. The core methodology has continued across
decades, but NHTSA has initiated improvements. The number of sites
has increased, drugs of interest have been modified to reflect use
across the country, and advances in technology have impacted how
data can be collected and specimens analyzed. Conducting an NRS on
a periodic basis (e.g., about every 10 years) allows NHTSA to
examine the prevalence of alcohol and drug use among drivers, and
trends across survey years. Given States are legalizing medicinal
and/or recreational use of cannabis, and other issues such as the
apparent increase in opioid use in the U.S., more information is
needed on the level of alcohol- and drug-involved driving to better
inform NHTSA’s countermeasure development. Roadside surveys provide
objective measures of alcohol and drugs in drivers’ systems when
they are actually driving. These measures are based on results from
breath tests and oral fluid samples collected using established
protocols. Analyses of these specimens allow for the quantitative
determination of alcohol and drug levels. Learning more about
alcohol and other drug prevalence among road users other than
drivers is new to this NRS. These other road users (ORUs) include
pedestrians, bicyclists, scooterists, and those using mobility
aids. NHTSA will conduct two studies. Study 1 will focus on drivers
but include convenience sampling of ORUs passing by the data
collection locations. Study 2 is a pilot test assessing the
feasibility of a NRS specific to ORUs. Both will collect breath and
oral fluid specimens, demographic information, and self-report
questionnaire data on roads across the country. Participation will
be voluntary and anonymous. Study protocols will be reviewed by a
U.S. Department of Health and Human Services-approved IRB. The only
personal identifiable information (PII) collected is oral fluid. No
DNA analyses will be conducted on the oral fluid specimens. These
will only be analyzed for the presence of alcohol and other drugs,
and specimens will be destroyed after the study is complete. The
results will be reported in aggregate form in research reports.
NHTSA anticipates obtaining a Certificate of Confidentiality from
the National Institutes of Health (NIH). Study 1 / National
Roadside Survey. This request is a voluntary, one-time survey. This
survey follows the prior NRS methodology but additionally includes
recruiting ORUs who are passing by data collection locations. Data
collection will occur in 60 primary sampling units (PSUs) using 5
locations at each PSU (300 locations total). There will be a single
data collection event at each location. The biological samples will
be sent to a toxicology lab for testing of the presence of alcohol
and other drugs. Participants’ responses to survey questions on the
use of drugs and traffic safety-related behaviors and attitudes
will also be analyzed. Study 2 / Pilot Test for Other Road Users.
Study 2 examines the viability of a stand-alone roadside survey
focused solely on ORUs. This effort uses 20 new data collection
locations, inclusive of 4 PSUs with 5 locations each. This effort
is to inform NHTSA on the feasibility of such a targeted roadside
survey and to determine the level of effort to execute a nationwide
study of ORUs. The same procedures as Study 1 will be used. NHTSA
will use the information from both studies to produce technical
reports presenting the findings. The technical reports will provide
only aggregate (summary) statistics and tables; no PII will be
retained or reported. The Study 1 technical report is for audiences
interested in traffic safety. The information from Study 2 will
also be used by NHTSA in consideration of research on
ORUs.
