DUI Stops & Rights

California field sobriety tests are roadside tasks officers use when deciding whether to arrest for DUI. Learn how the standardized battery works, how Vehicle Code section 23612 treats a PAS screen as a field sobriety test, where the observations appear in DMV and court files and what limits balance and eye tasks carry.

Police questions at a DUI stop can feel routine, and the answers may end up in a report. Drivers often hear simple advice online, like refusing to say anything at all. The short answer on DUI questioning rights is that the rules change with the stage of the encounter. Identification duties, investigative questions, custodial interrogation and chemical test advisements each follow different law, so one blanket script rarely fits every moment.

A sobriety checkpoint feels different from an ordinary traffic stop. No officer singled out the car, and every driver in line gets the same brief stop. The short answer on California DUI checkpoints is that courts allow this kind of stop without individual suspicion, but only within limits tied to highway safety and to the way officers run the operation. A court can review the actual checkpoint plan and conduct if a case arises from one.

A DUI case often starts with flashing lights in a rearview mirror. Questions about DUI traffic stop legality usually come later, once a driver reads the police report and wonders whether the officer had a valid reason to pull the car over. The short answer is that courts look at the facts the officer knew at each stage. A stop, a longer detention and an arrest each need their own justification, and a court reviews them one at a time.
