Roadside Agility Exercises

In almost every DUI case in Tampa, Hillsborough County, Florida, the officer will request that the driver submit to certain roadside agility tests which are often called field sobriety exercises (or FST). The tests are entirely voluntary. In other words, you do not have to take the field sobriety exercises.

Since the exercises are designed to assist the officer's testimony at a DUI trial, there is almost never an advantage to taking the tests. The field sobriety exercises are highly unreliable. Although the exercises are referred to as "standardized," the tests are subject to such variables as the driver's weight, athletic ability, medical disabilities, and age.

Testing conditions such as the emotional state of the driver, fatigue, proximity to passing traffic on the roadway, and unfamiliarity with the sobriety exercises all make the test unreliable.

Reasonable Suspicion for Field Sobriety Exercises

Under Florida law, before the police officer can request that a driver submit to field sobriety tests, the officer must have reasonable suspicion that the individual is driving under the influence. U.S.C.A. Const.Amend. 4. State v. Ameqrane, 39 So. 3d 339 (Fla. Dist. Ct. App. 2d Dist. 2010).

Other cases seem to indicate that probable cause is required before the officer can demand that the driver submit to agility exercises at the roadside. In certain cases, the criminal defense attorney can move to exclude any testimony about the subject's refusal to submit to the exercises if the officer does not warn the suspect that such a refusal can be used against him in court. 

Signs of DUI Impairment or Intoxication During the Initial Observations

The DUI officer will attempt to make this showing by claiming that the individual had one or more of the following indications of intoxication or impairment:

  • an odor of an alcoholic beverage on his breath (although the odor of an alcoholic beverage alone is probably not sufficient);
  • an admission that the driver consumed alcohol;
  • slurred speech;
  • bloodshot, watery or glassy eyes; or
  • uncoordinated movements and an uneven gait;
  • difficulty locating documents such as a driver's license, registration or proof of insurance.

In many cases, the arresting officer will recite exactly the same observations in every single case in which he makes an arrest for DUI. In fact, the officer will often recite the initial observations using exactly the same language in exactly the same order each time.

Types of Field Sobriety Exercises Used in Florida

The most commonly used roadside agility tests in Florida include the following:

  1. Eye test or HGN (Horizontal gaze nystagmus test);
  2. Finger to nose exercise;
  3. Walk and turn exercise; and
  4. One-legged stand exercise.

Reasons People "Fail" the Roadside Agility Exercises

For many people, certain factors can cause them to "fail" the test or show signs of impairment that have nothing to do with the consumption of alcohol or any controlled substance. Those issues can include:

  1. Medical problems that affect balance or coordination;
  2. Individuals over a certain age are at a clear disadvantage in taking the field sobriety exercises in Florida;
  3. Women charged with DUI who are wearing high heeled shoes or any individual who is wearing flip-flops can be at a huge disadvantage
  4. Individuals who have hearing problems and cannot hear the instructions for the field sobriety exercises are at a distinct disadvantage;
  5. Individuals for whom English is not their primary language are at a disadvantage in understanding the instructions for the field sobriety exercises.

In many of these cases, your attorney can show that the officer did not administer or grade your performance on the Field Sobriety Exercises correctly.
