The police asked me a bunch of questions and they never read my “Miranda rights”. Can what I told the police be used against me in court?

The answer is very likely YES. The police are not required to read you your Miranda rights unless you are in “police custody”. This normally means you have been identified as a suspect and you are not free to go. When you are stopped by a police officer who smells alcohol on your breath the law allows the officer to ask you how much you had to drink and to ask you to perform certain tests. You can refuse to answer his questions legally (other than to advise him of your name and provide him with proof of registration and insurance). You can refuse to take the field sobriety test. However, if you choose to answer his questions or take the tests that evidence can be used against you. Miranda rights are not required until you are arrested and in police custody.
