Field Sobriety Tests in Washington DUI Cases

What are field sobriety tests?

VOLUNTARY ROADSIDE TESTS

Field sobriety tests are roadside exercises — such as the walk-and-turn, one-leg stand and horizontal gaze nystagmus (eye) test — that officers use to look for signs of impairment. In Washington, these roadside tests are voluntary.

Why they are often unreliable

Nerves, fatigue, footwear, weather, road surface, injuries and medical conditions can all affect how a person performs. The tests must also be given and scored according to standardized procedures.

Officers sometimes describe performance in ways the video does not support. Comparing the report with body-cam and dash-cam footage is an important part of a defense.

Testing the Officer’s Observations

Chris Bugbee compares the officer’s report with the video and the standardized testing rules to find where the observations fall short.

WHAT TO KNOW

How field sobriety evidence is challenged

If the tests were not given or scored correctly, their results may carry little weight — and may not support the arrest.

Without reliable field sobriety evidence, the State may struggle to justify the arrest and the tests that followed.

Field sobriety tests are voluntary in Washington — but what happened at the roadside still matters to your case.
