Data Suggests Ride-Sharing May Be a Reason for Decline in DUI Arrests in LA County: LA County Sheriff’s Department Experience with Ridesharing
In 2010 and 2011, the Los Angeles County Sheriff’s Department was making about 3,100 arrests each year for driving under the influence. Then, in 2012, Uber arrived; Lyft followed the next year. Suddenly, the number of DUI arrests started to drop.
By 2017, DUI arrests had fallen 32% from five years earlier. Though DUIs started ticking up again in 2018 and 2019, they’re still 30% below their 2010 level. (Coincidentally, 2018 was the year recreational marijuana became legal in California.)
