There are a wide range of field sobriety tests (FSTs), including heel-to-toe, finger-to-nose, one-leg stand, alphabet recitation, modified position of attention, fingers-to-thumb, hand pat, etc. Most officers will use a set battery of three to five such tests.

Unlike the chemical test, where refusal to submit may have serious consequences, you are not legally required to take any FSTs. The reality is that officers have usually made up their minds to arrest when they give the FSTs; the tests are simply additional evidence which the suspect inevitable "fails". Thus, in most cases a polite refusal may be appropriate.
