The California Highway Patrol (CHP) charged 60 drivers with DUIs over an 8-hour period last weekend in central and south Sacramento.

CHP officials deployed 25 patrol units to scour freeways and surface streets in the area as part of a periodic program called RAID, which stands for Rapid Apprehension of Impaired Drivers, according to the Sacramento Bee.

Mike Bradley, a CHP spokesman, told the news source that arresting 60 drivers in one Sacramento night does not constitute an unusual event. “The south Sacramento area is a high-concentration area for alcohol and drug-related driving offenses. This is why Sacramento is one of the crash leaders in the state.”

He added that the police force typically arrests about 50 drivers for DUI charges in a single RAID effort. Most of the arrests are made between 11 p.m. and 2 a.m.

According to CHP officials, RAID is financed by anti-DUI grants from the California Office of Traffic Safety, which keeps statistics on Sacramento’s driving records and alcohol-related crashes.

Research by Mothers Against Drunk Driving estimates that one arrest for DUI is made for every 88 episodes of driving with a blood-alcohol concentration that is over the U.S. legal limit.
