The San Diego Police Department‘s crackdown on drunk driving during the July 4th holiday week continues with a checkpoint announced for Saturday night.
Officers will be stopping drivers to check for alcohol or marijuana impairment beginning at 11 p.m. Saturday and continuing until 3 a.m. Sunday.
Police said the checkpoint location will be chosen based on previous drunk driving crashes and arrests.
The checkpoints are regularly announced in advance because of the deterrent effect on people who might drink or smoke marijuana and then drive.
“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 said in announcing the Saturday night checkpoint.
