Long Beach police will run a driver’s license and DUI checkpoint Saturday, the night before St. Patrick’s Day, the department announced today.

The checkpoint will last from 6 p.m. to 2 a.m. somewhere in the Long Beach Police Department’s East Division, which covers most of the city east of Cherry Avenue.

These high-profile checkpoints are meant as a deterrent to drivers who might otherwise get behind the wheel while drunk or high.

“In California, alcohol-involved collisions led to 1,155 deaths and nearly 24,000 serious injuries in 2014 because someone failed to designate a sober driver,” the LBPD said in a news release. “Over the course of the past three years LBPD officers have investigated 1,024 DUI collisions, which have claimed 10 lives and resulted in another 392 injuries.”

The department reminded motorists that a DUI doesn’t mean only alcohol. Drug-impaired crashes have increased in recent years, according to authorities.

“If you take prescription drugs, particularly those with a driving or operating machinery warning on the label, you might be impaired enough to get a DUI,” police said. “Marijuana can also be impairing, especially in combination with alcohol or other drugs, and can result in a DUI.”
