The San Luis Obispo Police Department is conducting DUI patrols Saturday evening.
From 4 p.m. to 12 a.m., officers will be looking for drivers suspected of driving under the influence of alcohol and/or drugs.
Drivers caught driving impaired and charged with a first-time DUI face an average of $13,500 in fines and penalties, as well as a suspended license.
The San Luis Obispo Police Department said impaired driving is not just from alcohol. Some prescription medications or over-the-counter drugs may interfere with driving.
