| Sometimes, an officer will encounter a disabled driver who cannot perform the SFST. In such cases, some other battery of tests such as counting aloud, reciting the alphabet, or finger dexterity tests may be administered. Several appellate court decisions have indicated that, if you administer a test that requires the subject to respond orally in other than a routine information-giving fashion, such as requiring them to indicate the date of their sixth birthday, and if they are in custody at the time, you should administer the Miranda warning first, because you are seeking information from them that is testimonial or communicative in nature.
Tests given by some officers may include:
- Reciting the alphabet, or a portion thereof.
- Picking up coins off the ground.
- Patting or hand clapping.
- Estimating time.
- Counting backwards.
- Reciting the alphabet.
- Touching fingers to the thumb in a pattern set by the officer.
- Touching index fingers to the tip of the nose while the person’s eyes were closed and head tilted back.
Some have in the past involved strange, one-legged tapping on the roadway with a raised foot. These “made-up” tests were administered to subjects without any scientific or empirical basis for reliability in detecting an impaired driver. These tests were designed for failure, not for fairness. Even worse, police officers often forced people to perform these voluntary evaluations, thereby violating these citizens’ rights.
Some “non-standardized” tests are so ridiculous and difficult that proof of non-validity was easy with almost any jury or judge. Today, officers who lack NHTSA training invariably cannot cite any studies or scientific research which “validated” their tests, the scoring (e.g., “pass” or “fail”) or their testing methods. Almost always, no scoring system is used on tests which do not adhere to NHTSA guidelines. If non-standardized tests are used, the number of errors that are required for a subject to fail is totally subjective with each officer. Hence, the untrained officer is usually an easy target for a skilled and knowledgeable criminal defense attorney who knows the “limitations” of these field tests. |
