The DUI Law in California
Drunk driving is charged as DUI in California, at a blood alcohol level of 0.08 or more.
Driving in California is consent to a breath or blood test when an officer has cause to suspect DUI; the license case that follows a refusal or a failed test is run by the DMV, separately from the criminal case.
For charging and sentencing, California counts prior offenses within 10 years.
Who Makes DUI Arrests in Porterville
The Tulare County Sheriff's Office and the agency that reports for Porterville (filed by the FBI as Porterville Police Department) make the DUI arrests in and around Porterville.
The FBI's agency list also places two state agencies, two state police units, one other agency and one campus police department in Tulare County (the arrest records guide names each one); the Highway Patrol's two offices make the arrests on the state highways.
Together, the nine agencies in Tulare County with all twelve months of 2025 on file reported 13,886 arrests to the FBI that year, all offenses together; the FBI's count for Tulare County does not break DUI out.
Booking After a DUI Arrest in Porterville
A driver arrested for DUI and kept in custody goes to the county jail, whichever agency made the arrest. The jail, run by the Tulare County Sheriff's Office, held about 1,190 people on an average day in 2025 by the Vera Institute of Justice's count and has a jail page SearchSystems verified at tularecounty.ca.gov/sheriff. The Porterville inmate search guide covers the jail in full.
The Court Case
The District Attorney files the charge, and the case is heard in the Superior Court of California, County of Tulare.
The District Attorney's page SearchSystems verified is at tularecounty.ca.gov/district-attorney.
The court records page SearchSystems verified for the county is at online.tulare.courts.ca.gov.
California has no single public index of every trial court case; each court's records are looked up through that court.
The License Case
The court case is only half the record. The DMV runs a separate administrative case over the license, which can suspend it before the criminal case is decided, and the California Department of Motor Vehicles keeps the driving record the conviction goes on.
The Records a DUI Leaves
- The arrest report: from the agency that made the arrest, under the California Public Records Act.
- The court file: from the Superior Court of California, County of Tulare, kept by the Superior Court clerk.
- The driving record: from the California Department of Motor Vehicles.
