Field Sobriety Tests in Texas

Do You Have to Take a Field Sobriety Test?

The short answer? No. If an officer asks you to exit your vehicle, you must comply, but in Texas, the field sobriety tests themselves are voluntary. The real question is: should you refuse the field sobriety tests?

If a police officer pulls you over and wants to conduct tests for drunk driving, it often means he or she witnessed you driving erratically and has reasonable suspicion that you were driving while intoxicated. The officer wants to gain probable cause of this suspicion, which they need to have to arrest you and administer the real chemical tests down at the police station (you do need to take these chemical tests if you don’t want to risk your license being suspended).

Refusing to take field sobriety tests provides enough probable cause of a DWI for an officer to arrest you and take you to the station to conduct chemical tests. If you haven’t had anything to drink, acquiescing to the tests may save you the hassle of going down to the police station. However, if you are unsure whether your BAC is above the legal limit, the safest bet is usually refusing the field sobriety tests. It is easier for your Fort Worth DWI attorney to combat one potentially faulty chemical test before a jury than results of both chemical and field sobriety tests combined.

Field Sobriety Tests

There are three main types of field-sobriety tests: the horizontal-gaze nystagmus, the one-leg stand, and the walk-and-turn. Remember that officers often wear body-cameras or have a camera mounted in their vehicle when conducting these tests.

  • Horizontal-Gaze Nystagmus: This is also known as the pen test. The officer holds a pen or small flashlight in front of you and asks you to follow its movements with your eyes. The officer is looking for abnormal nystagmus—uncontrolled and repetitive eye movements. The officer then determines, based on his or her expertise, whether you passed the test. There is no second opinion or recording of your actual eye-movements, just the officer’s word that you failed.
  • One-Leg Stand: The name is self-explanatory. In this test, the officer asks you to stand on one leg and count to thirty. High heels, wind, unstable ground, shivering from cold, or simply poor balance could affect your ability to accurately perform this test, even if you are sober.
  • Walk-and-Turn: Again, if the officer asks you to exit your car, you must do so. If he asks you to walk in a straight line with feet touching heel-to-toe, then to turn on one foot and repeat, this is not mandatory. Often, this test is conducted in a location where the officer vehicle camera is recording the suspect and, like the one-leg stand, it can be difficult to accurately perform the test for various reasons. Feel free to save yourself the embarrassing footage and politely refuse.

Preliminary Alcohol Screening Breathalyzer

If an officer wants to conduct a breathalyzer test on the side of the road, it is not mandatory that you take the test. This is a preliminary alcohol screening. It is different than the chemical breath test administered in the controlled environment of the police station. Refusing to take a PAS breathalyzer can help your Fort Worth DWI attorney later challenge these tests in court.

Non-Standard Tests

Some non-standard field sobriety tests may include:

  • Counting the officer’s fingers
  • Stating the alphabet backward
  • Tipping head backward while feet are positioned together
  • Touching finger to nose while eyes are shut
  • Leaning backward with arms outstretched

If some of these “tests” sound ridiculous, it’s because they are. Often, cops are doing anything they can to arrest you for DWI. It is important that you remember you do not have to take these tests. Instead, you may state that you will not answer any questions without a lawyer, but you are not resisting. This establishes that you are asserting your right to remain silent while informing the officer that there will not be an altercation.
