In a word, NO. Field Sobriety Tests (FSTs) are generally not a good idea. The problem with FSTs is that they are typically given on the side of the road or on a nearby parking lot, at night, in the presence of an officer, under stressful inquisition type circumstances by an individual whose primary motivation is accumulating evidence to use against you in Court. The FSTs measure varying levels of physical coordination and the ability to listen and to follow what the officer is telling the suspect to do. The tests are not natural, some are open to serious critism and often times they are not properly explained by the officer. If a suspect chooses not to engage the FSTs, there is no penalty for that decision but the suspect is cautioned to be respectful and polite to the officer when making the decision.
