The current data from The National Center for Statistics and Analysis (NCSA) Fatality Analysis Reporting System (FARS) shows that, in Los Angeles County, 670 deaths were involved in a motor vehicle traffic crash in 2018 [1]. There is evidence that some drivers in California have accepted the practice of drinking and driving [2] even though there is a perceived high risk of arrest [3,4]. This situation may actually be underestimated due to underreporting of actual alcoholimpaired driving [5].Los Angeles County has a population size of just over 10 million inhabitants. In addition, there are 471,000 people who commute into Los Angeles County for employment [6]. Any of these people could have been one of the 670 alcohol-related fatalities in 2018 [1]. Preventing, if not mitigating alcohol-impaired driving in Los AngelesCounty can be achieved by applying countermeasures, such as regulations, court monitoring, offender treatment and monitoring, and enforcement [7]. For example, the latter has recently been shown, in the City of Los Angeles, to decrease the number of crashes, up to a week after, when utilizing low staffed sobriety checkpoints [8].
