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.

" Know Your Limit " Program
The Huntington Beach Police Department (HBPD) has become California’s “trainer” for other agencies interested in conducting the “Know Your Limit” Program. Officers visited ABC establishments during the hours of approximately 6:30 p.m. to 10:00 p.m. to educate citizens of the affects of alcohol on their body, potential for serious injury or death when driving while impaired, and negative financial penalties of a DUI arrest. Officers engaged the patrons in friendly conversation and explained their educational goal. Most patrons were very responsive and wanted to participate. The patrons were asked what they believe their BAC was based on the number of drinks they had consumed, what city they lived in to determine if they were a resident or a visitor, their age, their gender was noted, and they were asked if they would drive a vehicle. The officers then gave them a breath test and noted the BAC. The patrons were then provided with “Know Your Limit” stickers, educational materials, and $20 Uber cards (donated) for participating. HBPD also used their own funds to purchase a wrap for one of their police vehicles so it’s a half taxi, half police car and has the phrase “Choose Your Ride” on the vehicle. The vehicle was displayed near the establishments in which the programs were conducted. The vehicle was also used for several other DUI awareness activities, such as checkpoints. By adding the “Know Your Limit” educational component to enforcement, it has increased public awareness, strengthened community trust and respect for law enforcement, provided positive feedback from citizens, created discussion about the issues of DUI, and identified future needs or shifts in enforcement/education efforts. The HBPD conducted 16 “Know Your Limit” details, provided 1,144 breath tests, visited 79 bars/restaurants, and trained 14 other agencies from Orange, Riverside, Los Angeles, and Sacramento Counties.

Combined Responsibility to Educate and Eliminate Drunk Driving – MADD
MADD continued its collaborative efforts with community and law enforcement partners to work towards eliminating drunk driving and preventing underage drinking by providing awareness and prevention programs statewide. Educational programs were presented in 143 schools throughout California to increase awareness of the devastating effects of drunk driving to both youth and adult audiences, reaching over 25,800 students, parents, and educators. Community awareness and prevention presentations were conducted at 325 local community events reaching more than 70,389 community members. These presentations included Power of Parents, Power of Youth, Zero Tolerance/ Underage Drinking Prevention presentations, Victim Survivor Stories, and the Consequences of Drunk Driving. Booths with resource materials were displayed by MADD at 146 community events, schools, local businesses, and military bases. These events included Safety Stand Downs, National Night Out events, health and safety fairs, Red Ribbon Week events, Sober Prom/Sober Graduation, and drug and alcohol conferences. Through these combined outreach efforts, MADD distributed over 363,450 pieces of educational material.

California College DUI Awareness – RADD
UC Berkeley Safe Transportation Research and Education Center (SafeTREC), partnered with RADD®, the entertainment industry’s voice for road safety, to conduct the RADD® California College DUI Awareness Project through promotion of the RADD Designated Driver/AT Rewards program on 35 college campuses in California. In honor of the project’s success, Toyota Motor Sales, USA, generously donated campus message materials: 100 “RADD Crew” t-shirts for campus staff, 3,000 sunglasses, and new graphic wraps for RADD’s Toyota vehicles (Scion xB and Prius C). RADD conducted one statewide training; four regional trainings, nine campus trainings and one large community RBS training for RADD Retail Rewards partners. Program highlights included expanding partnership from 32-35 college campuses, 219 campus activations, distribution of 23,940 RADD Pledge Cards, 520 RADD wristbands, with a total on-campus exposure to 93,571 students. Soaring beyond its former scope of “college students on campus,” the campaign served an expanded scope-of-work (all 18-34 year olds) by adding messaging elements off-campus, on-air, and at music festivals. Wide penetration of 2,900,000 unique impressions was achieved through radio, TV, and digital campaigns that resonated with our young adult audiences on campus, in the workplace, at home, on military institutions, in dorms, and out on the town. Social media numbers skyrocketed resulting in a 95 percent increase in RADD’s Facebook likes, a 99 percent increase in Instagram followers, and a 95 percent increase in Twitter followers, plus 25,000 YouTube views, for a combined total of 2,500,000 online impressions. The list of RADD Retail Rewards partners increased from 400 to 425, as staff focused on recommitting existing partners while adding key hospitality zones in areas adjacent to downtown Long Beach, plus downtown San Francisco, the Central Valley, Berkeley, and San Diego’s North County, home of UC San Diego, and USMC Camp Pendleton.

Youth to Youth: Ensuring More Futures - Friday Night Live
This grant focused on youth designed and driven campaigns, with a focus on engaging peers, parents, and the larger community, on reducing underage drinking and traffic safety issues in 32 different communities across California. Projects ranged from local policy, to social norms campaigns, merchant education, parent presentations, and a variety of other efforts aimed at reducing traffic fatalities. Students also hosted a wide range of activities on their campuses to ensure that the campaign efforts had a constant presence at their schools/communities. All sites conducted Roadwatch surveys; a statewide assessment of driver behaviors. They used this activity to launch their larger, yearlong campaigns. Included with the Roadwatch opportunity was a California Common Core math curriculum lesson that was designed to be utilized in classrooms as a process for helping a larger audience understand the data and its implications in their lives. Another important aspect of the project is the Youth Traffic Safety Summit. Youth and adult participants attended two days of traffic safety education and support to create year long campaigns for their individual communities. This year, over 730 participants, representing 32 counties came together to make plans to improve traffic safety in their communities in the upcoming year.
