The California Highway Patrol said today that it will have enhanced presence on state roadways from 6 p.m. Dec. 24 through midnight on Dec. 27.
Officers will focus on possible cases of motorists driving under the influence.
"The holidays are about family, friends and celebration. Unfortunately, it's also a time of year when we see too many alcohol-related fatalities," said CHP Commissioner Joe Farrow.
CHP said 37 people died on California roads during last year's Christmas-enforcement period, with 23 being killed in alcohol-related crashes.
Never miss a local story.
Along with increased enforcement, CHP is asking motorists to call 911 to report suspected drunk drivers. Callers should be prepared to provide dispatchers with a description of the vehicle, its location and direction of travel.
CHP said it will conduct a similar holiday enforcement effort from 6 p.m. Dec. 31 through midnight on Jan. 3.
