You can be questioned, without a lawyer present, only if you voluntarily give up your rights and if you understand what you are giving up. If you agree to the questioning, then change your mind, the questioning must stop as soon as you say so or as soon as you say that you want a lawyer. If the questioning continues after you request a lawyer and you continue to talk, your answers can be used against you if you testify to something different.
You may be required to give certain physical evidence. For example, if you are suspected of driving under the influence of alcohol, you may be requested to take a test to measure the amount of alcohol in your system. If you refuse to take the test, your driver’s license will be suspended and the refusal will be used against you in court.
Once you have been “booked,” (meaning your arrest has been written into official police records, and you have been fingerprinted and photographed) you have a right to make and complete three telephone calls that are free within the local dialing area.
