It is extremely important to understand the difference between field sobriety tests and a test of your breath or blood for alcohol concentration.

If you refuse to successfully complete a breath or blood test to determine alcohol concentration, you will lose all driving privileges for twelve months. 

There is no such penalty for refusing to perform field sobriety tests like the walk and turn, one leg stand, finger to nose, finger count, any verbal tests that requires reciting the alphabet or numbers, or horizontal gaze nystagmus.

Horizontal gaze nystagmus is a test in which the person will be asked to follow the top of a pen being moved in front of his/her eyes.

You have the right not to perform these field sobriety tests.
