Did You Know? Facts From an Oakland DUI/DWI Defense Attorney

California DUI arrests require two separate cases:

1) The DMV action wherein they will attempt to suspend one's driving privilege
2) The case in criminal court for driving under the influence of drugs and/or alcohol.

Some of the best defenses to DUI or drunk-driving charges are those where the defendant has either refused a chemical test or where he claims and has evidence that someone other than the defendant was driving the car.

  • Police officers often make many mistakes in their reports which provide possible defenses to DUI and drunk-driving charges.
  • DMV proceedings are entirely separate from any court proceedings.


You have 10 days from the date of your arrest to defend your right to drive.  If you delay, the DMV will automatically suspend your license 30 days after your arrest.

DO NOT DELAY, if you have been arrested for a DUI, your privilege to drive may be in the process of being suspended.

“The death penalty is a lie, a misguided mistake born of anger and frustration. Capital punishment has become a perverse monument to inequality, to how some lives matter and others do not. It is a violent example of how we protect and value the rich and abandon and devalue the poor. The death penalty is a grim, disturbing shadow formed by the legacy of racial apartheid and bias against the poor that condemns the disfavored among us, but corrupts us all. It’s the perverse symbol elected officials use to strengthen their ‘tough on crime’ reputations and distract us from confronting the causes of violence. It is finally the enemy of grace, redemption and all of us who recognize that each person is more than their worse act.”
