Drunk Driving / DUI / DWI

If you have been arrested for Driving Under the Influence of Alcohol or Drugs (DUI), you could face a variety of serious penalties – including jail time and the suspension or revocation of your driver’s license. The severity of these penalties can depend on your blood alcohol level, your age, your prior record, whether you were involved in an accident, if you had minors in the car at the time and your manner of driving at the time of the arrest. In addition, the Department of Motor Vehicles (DMV) will seek to suspend or revoke your driver’s license irrespective of the result in criminal court. Some of these rights are time sensitive and require setting a hearing within ten (10) days of your arrest. Derek Ewin has literally handled hundreds of these types of cases. An experienced attorney, like Mr. Ewin, can help you navigate through the courts and DMV and greatly increase your likelihood of getting the best possible outcome.

Some of these charges are called wobblers. Wobblers can be charged as either a felony or a misdemeanor. Derek Ewin has worked on all of these types of charges over his career.
