DUI Criminal Cases

A Contra Costa County DUI arrest usually initiates two separate cases. The first case is the Contra Costa County DUI criminal case which will be prosecuted by the Contra Costa County District Attorney's office at the Superior Court located in Walnut Creek, Martinez, Richmond, or Pittsburg. The Contra Costa County District Attorney will almost always charge a person with at least two separate criminal violations following a DUI arrest made in Contra Costa County by a California Highway Patrol officer, Contra Costa County Deputy Sheriff, or local police officer of Antioch, Brentwood, Clayton, Concord, Danville, El Cerrito, Hercules, Lafayette, Martinez, Moraga, Orinda, Oakley, Pinole, Pleasant Hill, Pittsburg, San Ramon, Richmond, San Pablo, or Walnut Creek.

The first Contra Costa County DUI charge is for driving under the influence of alcohol, medication or drugs in violation of California Vehicle Code section 23152, subdivision (a). The second Contra Costa County DUI charge is for driving with a blood alcohol level (BAC) of .08 percent or greater in violation of California Vehicle Code Section 23152, subdivision (b). If a Contra Costa DUI arrest involved an accident resulting in an injury to a person other than the individual arrested for driving under the influence, a more serious misdemeanor or felony DUI will usually be charged by the Contra Costa County District Attorney alleging a violation of California Vehicle Code section 23153, subdivision (a) and California Vehicle Code section 23153, subdivision (b).

The second case is a Department of Motor Vehicles administrative per se (APS) case, in which the arrested person's privilege to drive in California is at risk of being suspended. Drivers arrested for DUI driving with a blood alcohol concentration of .08% or higher in California have only 10 days from the date of arrest to request a DMV administrative per se (APS) hearing. If a DMV hearing is not requested within ten (10) days of the arrest, any California driver's license issued to the person arrested will automatically be suspended thirty (30) days from the date of the arrest for a minimum of four (4) months. If the person arrested in Contra Costa County for driving under the influence (DUI) has an out of state driver license, the privilege of that person to drive within the State of California will be suspended indefinitely thirty (30) days from the date of the arrest and may not be restored until a California DUI school is completed. Additionally, a driving suspension imposed by the California Department of Motor Vehicles for a DUI will usually have an effect on the out of state driver's license.

California DMV hearings are technically complex, and should be handled by lawyers having extensive experience handling California DUI and California DMV cases. In order for the California Department of Motor Vehicles (DMV) to suspend a driver's license, the Hearing Officer must only prove by a preponderance of the evidence that the California Highway Patrol officer, local police officer, or Contra Costa County Deputy Sheriff had reasonable cause to believe that a violation of California Vehicle Code Section 23152, Section 23153 or Section 23154 (relating to motorists on probation for DUI and driving with a blood alcohol level of .01 percent or greater) was committed, that the California DUI arrest was lawful, and that the driver had a blood alcohol concentration (BAC) of .08 percent or greater. California DMV administrative hearings can be won, but usually only by an attorney with specialized knowledge of the hearing process, the type of evidence presented and familiarity with the possible defenses.

The stakes are high in a Contra Costa County drunk driving case. A person accused of driving under the influence faces the possibility of jail, large fines, driver's license suspensions, mandatory alcohol education classes, ignition interlock devices, and other punishment. For that reason, it is critical that anyone who has been arrested for driving under the influence or is being investigated for DUI in Contra Costa County have a qualified California DUI lawyer handling the case.

Contra Costa County General Information

Contra Costa County (Spanish for: Against the Coast) is a suburban county in the San Francisco Bay Area of the state of California. Contra Costa County was one of the original counties of California, created in 1850 at the time of statehood. The county was originally to be called Mt. Diablo County, but the name was changed prior to incorporation as a county. The county's Spanish language name means opposite coast, because of its location opposite San Francisco, in an easterly direction, on San Francisco Bay. Southern portions of the county's territory, including the all of the bayside portions opposite San Francisco, and Northern portions of Santa Clara County were given up to form Alameda County in 1853.
