Chula Vista Police announced plans for a DUI and license checkpoint at an undisclosed location somewhere in the city limits on Friday night.
Officers will be stopping drivers between 6 p.m. and midnight to check for alcohol or marijuana impairment as well as proper licensing.
Local law enforcement frequently announce these checkpoints in advance because of the deterrent effect on people who might drink or smoke to excess and then get behind the wheel.
Checkpoint locations are chosen based on the frequency of past DUI accidents and arrests.
Consequences for drivers caught impaired include jail time, fines, fees, DUI classes, license suspensions and related expenses that can exceed $10,000.
