Local law enforcement authorities have planned DUI checkpoints for Friday night in both San Diego and Vista.
At both checkpoints, whose precise locations were not announced in advance, officers will be checking drivers for alcohol and marijuana use as well as proper licensing.
The San Diego Police checkpoint will be in operation from 11 p.m. Friday until 3 a.m. Saturday.
In Vista, San Diego Sheriff‘s deputies will be stopping drivers from 8 p.m. Friday until 2:30 a.m. Saturday.
Law enforcement authorities regularly announce the checkpoints in advance because of the deterrent effect on people who might drink alcohol or smoke marijuana to excess and then drive.
“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,” said San Diego Police Officer Mark McCullough.
