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?

Call us today. Do not wait to get the justice you deserve.
