NO! Since you cannot be compelled to be a witness against yourself, you have no legal obligation to perform the field sobriety tests. Furthermore, if you are arrested for the offense of Driving While Intoxicated or Driving Under the Influence, you cannot be forced to give a breath or blood sample. There are legal ramifications for refusing to take a blood alcohol concentration (BAC) test. If you refuse to take a BAC test your driving privileges may be suspended for 60 days up to 2 years. However, if you take a BAC test and fail your driving privileges could be suspended from 60 days to 1 year
