Subjected to a Field Sobriety Test? We Fight For You When It Matters Most

Field Sobriety Tests in Nevada

If you have been pulled over by a police officer who has probable cause to believe that you are driving under the influence, then he may administer some field sobriety tests. They are meant to assess whether you are intoxicated or not.

These tests include:

  • The walk and turn test: The officer will be testing your balance and ability to follow instructions. Failing at 2 or more aspects of this test make it appear that you have a blood alcohol concentration (BAC) higher than 0.08.
  • The horizontal gaze nystagmus test (HGN): Nystagmus refers to uncontrollable eye-jerking, which the officer will look out for as you are asked to follow an object with your eyes. Nystagmus can be a symptom of a BAC higher than 0.08.
  • The one-leg stand test: You have to stand on one leg while further performing mental tests.

There is a great deal of room for human error in these tests. The officer may fail to administer the test properly. You may not be able to understand the instructions, or may not be coordinated. Factors such as age, weight, medical conditions, or even feeling nervous can severely skew any of these results. In any such instance, you could be mistakenly charged with a DUI. According to the National Highway Traffic Safety Administration (NHTSA), these field sobriety tests can only be 65-77% reliable at best. In fact, the NHTSA approximates that as much as 25% of those charged with a DUI because of field sobriety tests were not actually under the influence. An experienced DUI defense attorney will know how to probe for the evidence to show that your test results are highly questionable.
