The Long Beach Police Department plans to set up a DUI and driver’s license checkpoint Friday between 6 p.m. and 2 a.m. in the east patrol division of the city.

A DUI does not only result from consumption of alcohol; drivers can be too impaired to drive from taking certain prescription drugs or consuming marijuana, the department warned in a statement.

California has had a “disturbing” increase in drug-impaired driving crashes in recent years, police said.

“The deterrent effect of High Visibility Enforcement using both DUI checkpoints and DUI Saturation Patrols has proven to lower the number of persons killed and injured in alcohol or drug-impaired crashes,” police said. “Research shows that crashes involving an impaired driver can be reduced by up to 20 percent when well-publicized proactive DUI operations are conducted routinely.”

Police did not reveal exactly where the checkpoint would be.

Signal Hill Police will also be holding a DUI checkpoint on the same night.
