If you, a relative or someone you know and care about has been arrested for driving under the influence (DUI) in San Mateo County, please read the material presented in this website, then seriously consider hiring a locally based lawyer who specializes in DUI defense.

California DUI Laws are complicated. A San Mateo DUI arrest most often initiates two separate DUI cases. The first DUI case is the criminal case, while the second DUI case is the DMV case. From the moment a person is stopped by a California Highway Patrol Officer, local Police Officer, San Mateo County Sheriff's Deputy, or other law enforcement officer, they are being subjected to a DUI investigation and incriminating evidence is being collected. A driver's physical appearance and performance on so-called field sobriety tests will be recorded on a police report, as well as the result of a Preliminary Alcohol Screening device, evidential breath test, or evidential blood test.
