What Are Field Sobriety Tests?
Field sobriety tests are administered to determine if a police officer has probable cause to make a DUI arrest. Most police departments follow the National Highway Traffic Safety Administration’s DWI Detection and Standardized Field Sobriety Testing Student Manual. There are many instructions on how to conduct the sobriety test and any departure or failure of an officer to follow proper procedure may be grounds for having a DUI charge dismissed.
If you are charged with a DUI after a sobriety test, it will be in your best interest to challenge the allegation. As a criminal defense attorney, I will investigate the scene where a field sobriety test was given. I review the actions of the arresting officer and identify mistakes that compromise the reliability of the field sobriety test.

Are Field Sobriety Tests Reliable?
A field sobriety test is supposed to determine whether or not an officer has probable cause to arrest a suspect for drunk driving. How well or poorly someone does on a field sobriety test is, however, a matter of judgment on the part of an officer. Practically speaking, this means an officer acts as judge and jury in the field. If he makes a mistake or fails to properly follow procedure, there is no one there to advocate on your behalf.
Secondly, field sobriety tests are really nothing more than agility tests. Some people, due to inner ear problems, age, health conditions or poor balance, will fail them even when sober. In fact, researchers S. Cole & R.H. Nowaczyk conducted a study involving 21 people with a BAC of .00 performing the field sobriety test. When officers reviewed the film of these test subjects, 46 percent of them thought they had too much to drink. This is a good indication of just how unreliable a field sobriety test can be.
The Importance Of How A Field Sobriety Test Is Conducted
Officers should receive instruction in how to properly administer a field sobriety test. They should be knowledgeable of the procedures and instructions in the DWI Detection and Standardized Field Sobriety Testing Student Manual involving where a test should be conducted, what should be done when a test subject halts, moves from one foot to the other, or moves his arms up and down while trying to walk a straight line. That’s why I recover dashboard footage of a field sobriety test when possible.
I also inspect the area where a test was conducted, noting any uneven pavement, gravel or inclines. In many cases, I can have a DUI charge dismissed if there are clearly identifiable violations of proper procedure when administering the field sobriety test.
