Am I Required to Submit to Field Sobriety Testing?

There is no legal requirement to take any field sobriety tests and as such, we recommend that you do not take them. These are subjective tests that are only 65%-77% correct when administered in perfect conditions, administered exactly as designed, and evaluated impartially.

You may absolutely decline to take these tests and it is often wise to do so. There are no consequences for refusing to take them (note that this is different than blood and breath tests which may have consequences for refusal, including the suspension of your driver's license). If you do take the tests, they can be used by the police as evidence against you.

The officer already thinks you are impaired — why else would they request you take the test? An officer who already is biased against you is the one who will be grading your performance. In America, you do not have to prove your innocence; it is the duty of the State and the police to prove you are guilty. You have no obligation to do the officer’s job or help at this point.

The best response is to ask the officer, "Am I required to take these tests?" The honest answer is no. Any other response could leave a jury with the impression the officer is deceptive. At this point, tell the officer that you would like to talk to an attorney before deciding what to do. The officer most likely will refuse your request, but there is a considerable difference between refusing to take the tests and asking to talk to an attorney before making your decision.

Whether you refused field sobriety tests or took and “failed” roadside testing, May McKinney can offer valuable insight regarding your rights and legal options. Call (615) 265-6383to learn more!

Types of Field Sobriety Tests

The National Highway Traffic Safety Administration (NHTSA) worked to develop three field sobriety tests:

  • Walk and Turn
  • One Leg Stand
  • HGN testing

Walk and Turn

In this test, the subject is told to take several steps, heel-to-toe in a straight line. Then he or she must turn on one foot and return back following the same process. The examiner is looking for two or more signs of impairment including: if the subject doesn't listen to the instructions before beginning to walk, stops at any point to regain balance, veers off the line, does not touch heel-to-toe, needs arms to balance or does not turn as directed.

One Leg Stand

This requires the subject to raise one foot six inches off the ground while counting aloud until told to stop (it is supposed to be for thirty seconds). The examiner watches for two or more signs the subject is struggling to balance including hopping, swaying, using arms or placing the foot back down.

HGN Testing

HGN stands for Horizontal Gaze Nystagmus. This is an involuntary jerking of the eyes as they look to the side. It occurs naturally but can be exaggerated if an individual is impaired by alcohol. The subject will be asked to follow an object (like a pen) with their eyes in a slow horizontal motion. The officer will be looking to see if the eye can follow the object smoothly. If the eyes do jerk, the officer will take particular note if it occurs at lesser angles of viewing.

    "Incredibly helpful"
    This was my first experience ever being accused of a crime and I was very nervous and scared. Rob and his staff were incredibly helpful, answering all of my questions and putting my mind at ease throughout the process. In the end, we were able to get everything dismissed successfully. Although in the grand scheme, my case was a relatively minor one, Rob always was there to help and it was clear that his knowledge and experience would be hard to find anywhere else. I would absolutely recommend Rob and his team to anyone looking for a defense attorney.
