know your rights

Washington State has some of the toughest DUI laws in our nation. These laws carry increasingly severe penalties for those who drink and drive. Washington lowered the BAC limit from .10 to 0.08 in January of 1999. Drivers with a blood-alcohol concentration (BAC) at .08 or above can now be convicted of driving under the influence of alcohol. In addition, because public sentiment is so very negative toward drunk drivers, prosecutors will often pursue a DUI conviction even when the driver’s test result is well under .08! This is possible because they can obtain a conviction if they can show the person drove while “affected by” alcohol, and/or marijuana or any drug, including prescription or over-the-counter medications.
