Non-Standardized Tests: Manual Dexterity
Of the non-standardized field sobriety tests, three of them are designed to test manual dexterity. None of them are necessarily scientifically validated, though they do have the advantage of not relying on balancing or standing in order to make an assessment. Your Sacramento drunk driving attorney will be able to tell you what the flaws are for the different types of tests.
The picking up coins test is conducted in two simple steps. First, the police officer places coins on a flat surface, such as the hood of the car. Then, the officer asks the driver to pick up the coins using only one hand. This is a rarely-used test.
The handwriting test also consists of two steps. Basically, the driver writes and the officer decides whether or not the handwriting looks like it was produced by an individual who is under the influence of alcohol. Studies do not validate the accuracy of officers’ handwriting observations. Though changes in handwriting can be seen at each level of intoxication, those changes could not be attributed solely to the consumption of alcohol. In addition, other studies show that handwriting samples taken before and after drinking show deterioration but not any kind that could be used to reliably gauge the BAC of the writer.
The hand pat test is one that is more challenging. The driver places his or her hand in front with the palm up. Then, the other hand is placed on top of that hand so that the palms touch. The subject is to then pat palm to palm, rotate the top hand, pat the top of that hand to the palm below it, and then repeat the process. As the driver proceeds with this test, the police officer will ask him or her to increase the pace of the movements, and then ask him or her to stop. This test is considered designed for failure because even a sober individual will eventually make the wrong motion.
