In less than a month, five CHP officers have been struck by cars — three driven by motorists accused of driving under the influence of drugs or alcohol.

As a result, the CHP has launched an anti-DUI campaign across the Bay Area to crack down on people driving under the influence, the agency announced in a news release.

Until Jan. 31, all available personnel, including command staff, middle managers, supervisors and officers will patrol freeways for impaired drivers.

Of the three DUI collisions, one resulted in the death of rookie CHP Officer Andrew Camilleri, who died Christmas Eve when a suspected drunk driver slammed into the back his SUV while he and his partner were parked on the shoulder of Interstate 880 in Hayward. His partner, Jonathan Velasquez, was injured but survived.
