How Do Washington Police Know If You're Driving Under the Influence?
During a field sobriety test in Washington, you may be asked to:

- Walk in a straight line, placing the heel of one foot directly in front of the toes of your other foot, then turn and walk back to the police officer
- Track a moving object with your eyes while keeping your head still
How Do Police in Washington State Determine Your Blood Alcohol Content?
Based on your field sobriety test, the police officer may have probable cause to arrest you under suspicion of driving under the influence. Police may subsequently administer a breathalyzer test, a blood test or a urine test to measure your blood alcohol content.
If you refuse to take a BAC test, Washington laws require officials to automatically suspend your license for at least one year.
