As Americans hit the road this holiday season to celebrate with family and friends, it’s important that we all drive safely—and safe driving means sober driving. That’s why NHTSA is again kicking off our annual Drive Sober or Get Pulled Over holiday campaign (December 13-31) to raise public awareness of the dangers of drunk driving.
You can’t drive safely if you’re impaired. That’s why it’s illegal everywhere in America to drive under the influence of alcohol, marijuana, opioids, methamphetamines, or any potentially impairing drug–prescribed or over the counter.

National Distracted Driving Telephone Survey Finds Most Drivers Answer the Call, Hold the Phone, and Continue to Drivehttps://www.nhtsa.gov/document/national-distracted...
From 2011. The National Highway Traffic Safety Administration conducted the first of several periodic national surveys of distracted driving to monitor the public’s attitudes, knowledge, and self-reported behavior about cell phones, texting, and driver choices. The 2010 survey was administered by telephone to 6,002 respondents 18 and older, with 4,877 interviews completed with respondents who were using landline phones and 1,125 interviews completed with respondents who were using cell phones. The survey over-sampled young adults 18 to 34. Interviewing ran during November and December 2010.

The use of medications and multiple medications becomes more prevalent with increasing age. This pilot study explored the relationship between polypharmacy and driving functioning through separate but related research activities. A patient-level administrative claims database containing prescription information as well as E-codes identifying the incidence of motor vehicle injuries was mined, yielding combinations of drugs that became inclusion criteria in a following field study of driver performance among 44 older adults (range: 57 to 89; mean: 79). Driving performance evaluations by an OT/CDRS, a brake response time measure, and functional screening measures were conducted for the study sample, whose drug profiles were documented through a “brown bag” review by a licensed pharmacist. The relationship between medication usage and each of these outcome measures was examined in descriptive data summaries and regression analyses. The driving evaluations were carried out in a dual-brake vehicle also equipped with speed sensor (OBD-2), GPS logger, and two miniature video cameras (driver’s face and forward road views) plus digital recorder. A subsample allowed the same instrumentation package to be installed in their private cars for a week of independent driving; this supported an analysis of within-subject variability in driving behavior during a formal driving evaluation versus independent driving.

These six case studies examine high-visibility enforcement (HVE) programs including discussion of HVE history, enforcement strategies, visibility elements, operation, resources, use of media, educational components, funding, political and community support, barriers encountered, and strengths of the program. Some include statistics on the HVE operations (e.g., number of checkpoints, number of officers per saturation patrol) and impaired-driving crashes, arrests, and/or convictions before and after the program began.
Intelligent Speed Adaptation (ISA) represents a promising approach to reduce speeding. A core principle for ISA systems is that they provide real-time feedback to drivers, prompting them to reduce speed when some threshold at or above the limit is reached. The overall goal of the study was to provide insight into the effectiveness and acceptance by young drivers in the United States, of an ISA consisting of an Active Accelerator Pedal (AAP) system. The project involved the design, development, and production of an AAP that included speed mapping and data logging and its installation in two vehicles used for data collection. The AAP system provided increased accelerator pedal resistance above the 2 lbs. of the original pedal up to a maximum total of 38 lbs. if a person exceeded the posted speed limit. If drivers allowed the vehicle speed to drop back to or below the speed limit, the pedal force returned to normal. After successful development and pilot testing of the system, researchers conducted two separate studies with young drivers (18-24 years old) to examine its speed reduction effects, the workload experienced, and satisfaction with the system. For one study, researchers defined a driving route within the Kalamazoo/Portage area of Michigan consisting of 6 segments. Twenty-two pairs of participants (n=44) matched on age and gender drove the route twice on a single day—morning and afternoon— with one participant in each pair having the AAP active in the afternoon drive. Results of this study showed the AAP led to less speeding and somewhat increased driver workload when activated. The second study involved giving an AAP-equipped vehicle to 4 participants to use for 15 days in place of their personal vehicles. The system was off during the first 5 days, activated during the second 5 days, and again turned off for the final 5 days. Results of this study were encouraging with 2 of the 4 participants showing significantly reduced speeding 5+ mph over the limit when the pedal was active. Participants expressed support for the widespread use of the AAP if it saved them money (e.g., lower insurance premiums).They liked the increased awareness of the speed limit but disliked being slower than prevailing traffic. Overall, the studies produced results not unlike those reported in the literature from Europe. The AAP system showed promise for reducing speeding among young drivers in the United States, but more research is needed to further refine the system and understand how best to introduce it into the total vehicle fleet.

The communities of Hartford, Connecticut, and Syracuse, New York, implemented year-long campaigns to test whether NHTSA's high-visibility enforcement (HVE) model could be applied to reduce two specific forms of distracted driving – driving while talking on a hand-held cell phone or texting.

The American Society on Aging (ASA) and the National Highway Traffic Safety Administration (NHTSA) developed this toolkit for people working directly with older adults to: Understand the issues related to older drivers and later-life independence and mobility; Plan and implement public information events for older drivers, their families and loved ones, and other community members and organizations; and Evaluate the effectiveness of older driver public information events, community understanding of safe mobility issues, and progress
This project was conducted to provide an objective measure of the relationship between older adults’ scores on a set of driving assessment tools and their (serious point) violations and crashes over a period of 18 months following the assessments. An additional objective was to compare alternative methods of measuring driver exposure. The assessments were performed on 692 participants age 70 and older who visited one of four Maryland Motor Vehicle Administration (MVA) field offices between September 2008 and June 2009, under NHTSA contract DTNH22-05-D-05043, Task Order 10. The assessments emphasized cognitive performance domains, specifically visuospatial ability, speed of (visual information) processing, divided attention, visual search, working memory, and response planning or “executive function.” Contrast sensitivity was also measured, as well as simple and choice brake reaction time. The functional assessments examined in this research were computer-based and designed to be self-administered, although the assistance of a test administrator was always available and was required for some measures. Univariate and multivariate analyses examined the relationships between functional assessment scores and safety indicators. The measure of “executive function” (maze performance) was highlighted as a significant predictor of crash risk in the study results. This may be of interest to occupational therapy/driving rehabilitation providers as a potentially valuable tool to support clinical evaluations of fitness to drive; and, to developers of screening tools for early warning of driving impairments, and of products meant to educate older drivers and their families about age-related changes that impact safe driving.
