What to do after getting a DUI

If you have been charged with a DUI do not make the mistake of representing yourself in court. There are many variables that play into effect in determining guilty or not guilty. Hiring a criminal attorney ensures that the officers acted accordingly to bring a charge against you.

Here are some questions that a legal expert can help you review:

  • Did the cop have reasonable suspicion to pull you over?
  • Was the cop justified and taking your blood or searching your car?
  • Were the field sobriety tests conducted in a reasonable and professional manner or any of these things admissible in court?
  • Did the law enforcement officers seek a warrant?
  • Where your Miranda rights read properly for any questioning done for you?
  • What does the video and dashcam footage of the police car show are you actually guilty of the crime that they are alleging?
