The DUI Law in California
In California the offense is DUI, and the limit is 0.08.
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 Norwalk
The Los Angeles County Sheriff's Office and the agency that reports for Norwalk (filed by the FBI as Norwalk Police Department) make the DUI arrests in and around Norwalk.
The FBI's agency list also places 14 state police units, ten campus police departments, five other agencies and one state agency in Los Angeles County (the arrest records guide names each one); the Highway Patrol's 14 offices make the arrests on the state highways.
Together, the 47 agencies in Los Angeles County with all twelve months of 2025 on file reported 111,326 arrests to the FBI that year, all offenses together; the FBI's count for Los Angeles County does not break DUI out.
Booking After a DUI Arrest in Norwalk

The Court Case
A DUI charge from Norwalk is brought by the District Attorney in the Superior Court of California, County of Los Angeles.

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 Los Angeles, kept by the Superior Court clerk.
