Alcohol-Impaired Driving

Impaired driving and alcohol-related crashes constitute a major threat to the safety and well being of the public. This is especially true among young people age 15 to 24, where impaired driving is the leading cause of death. These programs aim to prevent people from driving under the influence (DUI) of alcohol or other drugs and to remove DUI drivers from the road. OTS grants use a comprehensive approach by funding educational, prevention, and enforcement programs and by focusing on high-risk groups.

  • Reduce the number of persons injured in alcohol-involved collisions.
  • Reduce hit-and-run fatal collisions.
  • Reduce hit-and-run injury collisions.
  • Reduce nighttime (2100 – 0259 hours) fatal collisions.
  • Reduce nighttime (2100 – 0259 hours) injury collisions.
  • Reduce the number of motorcyclists killed in alcohol-involved collisions.
  • Reduce the number of motorcyclists injured in alcohol-involved collisions.



Law enforcement agencies conducted high visibility enforcement during the NHTSA Summer and Winter
mobilizations. During these campaigns, officers conducted DUI checkpoints, roving DUI patrols, and DUI warrant/probation operations for those who failed to comply with court orders and habitual offenders identified as the worst-of-the-worst. Agencies also conducted “DUI Doesn’t Just Mean Booze” media efforts and DUI enforcement during Super Bowl Sunday, St. Patrick’s Day, Cinco de Mayo, Halloween,
and other local festivals and events with identified DUI problems. Local and regional media efforts were coordinated focusing on the awareness of impaired driving and the effects of illicit drug use and prescription medication when combined with alcohol, the tragedy caused by one’s choice to drive impaired, and the importance of designating sober drivers.


California’s high-risk DUI probationers continue to be intensively supervised to ensure compliance with court-ordered terms and to be held accountable when falling short of compliance. Throughout FFY 2018, grants to 13 county probation departments (Butte, Contra Costa, Fresno, Kern, Los Angeles, Placer, Sacramento, San Bernardino, San Diego, San Joaquin, Santa Barbara, Solano, and Tulare) facilitated the supervision of rotating caseloads numbering more than 1,880 probationers. Probationers were required to complete alcohol education programs, keep regularly scheduled office appointments, and were subjected to random afterhours home searches that included alcohol testing. Many of the probation departments participated in DUI warrant service operations with local enforcement agencies within their counties. Intensive supervision compels the vast majority to adhere to their terms of probation; however, when probationers failed to comply, they were held accountable.


Riverside County Department of Public Health
Riverside County Department of Public Health implemented the Be Wiser Teen Impaired Driving program at eight high schools during the FFY 2018 grant period. The purpose of the program was to engage youth in meaningful ways to reduce impaired driving behavior. This was addressed by training select youth advocates on each campus about the physical, legal, and emotional impact of impaired driving. These youth advocates were then challenged to lead campus wide activities aimed at educating their peers on the dangerous consequences of driving under the influence.

Program accomplishments include training approximately 191 high school youth to become traffic safety advocates. These engaged and informed youth then completed 16 awareness campaigns impacting 7,941 high school youth county-wide. The campaigns included hosting pledge tables, creating obstacle courses to highlight the impact impaired driving has on reaction time, reflexes, and perception while driving, as well as handing out impaired driving information such as DUI costs for underage drivers, tips for seeking sober rides, and how to talk to peers about impaired driving. Evaluations conducted by program staff concluded that 96 percent of youth trained found the information useful, and 98 percent felt the Be Wiser program would be beneficial to other school sites. In addition, pre/post surveys distributed to all sites during the project period revealed a 22 percent increase in knowledge around traffic safety and impaired driving education among Riverside County youth.



San Mateo County Superior Court
The San Mateo County Superior Court implemented a DUI Intensive Supervision Court designed to stop repeat DUI offenders. The goal of the program was to reduce recidivism rates and alcohol related collisions, injuries, and fatalities. These goals were achieved by mandatory court and probation supervision for all repeat offenders and mandated participation in treatment programs. The DUI Court Treatment Program admitted over 130 people into their Intensive Supervision DUI Court program during their first grant year and achieved a graduation rate of 88 percent.
