Are the field sobriety tests reliable?
Unfortunately, the field sobriety tests aren’t much more reliable than the breathalyzer. Even the most accurate DWI test (the combined horizontal gaze and walk and turn) is still inaccurate 20% of the time. Other field sobriety tests—like the one leg stand—are inaccurate up to 35% of the time. Sober people can fail these tests because they’re nervous or they simply don’t understand how the tests work. It’s important to find a DWI attorney who understands the fallibility of these tests and who can dispute these results in court.
