Do I have to do Field Sobriety Tests?
In Utah, there is no crime in declining field sobriety tests. In fact it is probably best not to. Very few people can do the tests as perfect as the police require for a "pass". You are only giving evidence against you.
Do I have to answer questions?
You are only required to give basic identifying information. You do not need to answer any questions, and probably should not. Ask for a Lawyer.
