Our Skilled Nampa Attorneys Challenge DUI Field Sobriety Tests
For an aggressive defense against driving under the influence charges
Standardized field sobriety testing (SFST) is alleged to prove a driver’s impairment through a series of activities conducted on the roadside. However, SFST often produces unreliable and insufficient evidence of impairment. Since our founding in 2001, Gulstrom, Roark & Govia PC has challenged SFST results, the administration of the tests and the flimsy science behind them. Our criminal defense lawyers meticulously review videos and police reports to determine if the manner in which you were tested was flawed and if there are inaccuracies in the conclusions presented by the prosecution.
One-leg stand test
To test your balance and coordination, a police officer may ask you to stand on one leg. Your medical conditions, injuries, weight or age may affect your ability to remain steady, as can wearing high heels or flip flops. The unevenness of the ground may also be a factor in your inadequate performance on the test.
Walk and turn test
To further assess your balance and coordination, the officer may instruct you to walk along a straight line by placing one-foot directly in front of the other and turning and repeating the process. As in the one-leg stand test, the ability to complete the task successfully may be affected by the following factors:

You may also have problems walking properly on cracked pavement, gravel, a slope or a slick surface.
Horizontal gaze nystagmus test
A police officer may conduct the horizontal gaze nystagmus (HGN) test by moving an object from side to side and directing you to follow it with your eyes. The HGN test is supposed to detect nystagmus — an involuntary jerking or bouncing eye movement, — which can be a sign of alcohol or drug impairment. However, nystagmus may also result from the following conditions:

Other evidence of impairment
The SFST is likely a crucial component to the prosecution’s case, especially if you refuse to submit to the Breathalyzer DUI test. The Boise or Nampa prosecuting attorneys may also rely on other evidence law enforcement officers included in their reports to which they may testify in court, such as the following:

Our law firm successfully introduces reasonable doubt by presenting valid alternative reasons for certain mannerisms, symptoms and actions.
