San Francisco DUI Attorney Robert Tayac

Specializing in DUI Defense in San Francisco & All Bay Area Counties

San Francisco DUI Lawyers, Law Offices of Robert Tayac Welcome to the website for San Francisco DUI lawyer and California DMV attorney Robert Tayac. If you, a relative or someone you care about has been arrested for driving under the influence (DUI) in San Francisco, or the surrounding counties of Alameda, Contra Costa, Marin, Napa, San Mateo, Santa Clara or Sonoma, or has received a letter from the California Department of Motor Vehicles Driver Safety Office threatening a driver's license suspension or driving privilege suspension, please read the material presented in the "What to Do First" and "DUI Overview" sections of this website, then seriously consider calling this office and hiring an experienced and locally based attorney who specializes in state and federal driving under the influence cases and California driver's license suspension matters.

California DUI Laws are complicated and DUI defense is a specialty. A California arrest for driving under the influence usually initiates two separate cases. The first case is a criminal case, while the second case is a DMV case. Those arrested for drunk driving who hold professional licenses (attorneys, physicians, nurses (registered nurses or licensed vocational nurses), physical therapists, teachers, certified public accountants (CPA's), pilots, stock brokers, bankers, veterinarians, dental hygenists, x-ray technicians, or other professionals) are at risk of having an additional case initiated by the board or commission which issued the license. This additional case may impact a person's license to practice their profession or affect their employment.

Individuals who hold positions of trust, such as law enforcement officers, fire fighters, scientists, teachers, commercial truck drivers, airiline pilots and those who hold security clearances will also be presented with specific legal issues requiring special attention.

Out of state drivers are presented with additional legal issues because the state which issued them a driver's license (home state) can be expected to initiate a case against their out of state driver's license which may carry additional consequences to those which may result from the California Department of Motor Vehicles suspension case. Almost all states have entered into several agreements to include the Interstate Driver's License Compact (DLC), Non-Resident Violator Compact (NRVC), and Interstate Driver's License Agreement (DLA). Collectively, these compacts and agreements are intended to further a national policy that there should be only one driving record for every person who drives or has ever driven a motor vehicle in the United States. The states which are members of these compacts share information through a computer database of information called the National Driver Register (NDR). This database contains information about drivers who have been convicted of minor traffic violations or had their driving privilege suspended or revoked in a state other than the one which issued them a driver's license for a serious traffic violation such as driving under the influence (called driving while impaired and DWI in some states), reckless driving, or other driving offenses. Once the home state is notified, the Interstate Driver's License Agreement requires a member state to post the out of state traffic conviction to their state's driver's license record and apply its own laws and consequences for the out of state conviction.

If a person is not a citizen of the United States, the risk exists of deportation, denial or significant delay of naturalization, exclusion from admission to the United States, exclusion from readmission to the United States following travel outside of the United States, denial of an extension of an H1B work visa or an upgrade to Lawful Permanent Resident status (also called, Resident Alien Permit Holder or Green Card Holder) or other renewal or upgrade of status with the United States. Immigration Agents regularly visit the county jails of each of California's fifty-eight (58) counties, review the records of individuals who have been arrested and interview those in custody in an effort to identify non-citizens who have been arrested for criminal offenses. Once identified, the United States Immigration and Customs Enforcement (ICE) Agent will place an immigraion hold on the arrested person which will prevent them from being released from the county jail by the sheriff's department or a California Superior Court Judge. For this reason, it is essential that release of a non-citizen be arranged as soon as possible following an arrest through bail or other means.

DUI Stop, Investigation, Arrest and Prosecution

Motorists are continuously being monitored and screened for suspicious activity and violations of the law by California Highway Patrol Officers, local Police Officers, County Sheriff's Deputies and other law enforcement officers. Even before being stopped, incriminating evidence is being collected and is sometimes recorded on video cameras mounted on the dashboards of police cars. Officers take note of so-called vehicle in motion DUI Driving Cues, the details of which are included in police reports.

The DUI investigation will continue or be initiated after the officers stop the motorist and make personal contact with the driver during the pre-arrest screening phase of a driving under the influence investigation. A driver's physical appearance and performance on so-called field sobriety tests will be detailed on a police report, as well as the results of a Preliminary Alcohol Screening (PAS) breath alcohol test. Sometimes, the conversation between the officer and the motorist will be recorded on an audio or video recording device. After the DUI arrest, the results of an evidential breath test, or evidential blood test will be included in the police report, as well as on a separate breath test strip or separate laboratory report of blood analysis.

While serious, the consequences of a first offense DUI arrest are less severe than those of a second offense DUI arrest. Multiple offense DUI cases such as a third offense DUI or even a fourth arrest for drunk driving will lead to increasingly serious DUI penalties which may include mandatory jail time or even a state prison commitment.

Additionally, the consequences of a DUI accident or a DUI accident causing injury or death are very severe and may lead to an actual jail or prison sentence even for a first offense driving under the influence conviction. Although there are DUI defenses which may apply to particular cases, many attorneys overstate the extent to which these defenses may be applicable to a particular individual's case. In fact, the California Department of Motor Vehicles has reported that 77.2 percent of DUI arrests made in 2009 resulted in convictions.

Additionally, it is important to understand that special rules, procedures and penalties apply to Federal DUI cases stemming from arrests in the Presidio National Park, Moffett Airfield or on other Federal property by the United States Park Police or other federal law enforcement agencies. Federal driving under the influence cases are prosecuted by the United States Attorney's office and upon conviction result in formal supervised probation by the United States Probation Office who will come to a person's home and may contact their employer.

If you are attempting to locate someone who has been arrested, feel free to use the directory in the "Finding Someone in Jail" section of this website. However, it is important to realize that several hours may pass from the time of the DUI arrest until a person has been transported to the county jail for booking. Depending upon other factors, several additional hours may pass until the individual has been formally booked (interviewed, fingerprinted, photographed, checked for warrants) and their name has been entered into the county jail's database. Feel free to contact this office any hour of the day or night if you need assistance locating someone who has been arrested or in facilitating communication with a reputable bail agent.
