We are committed to meeting your needs for any of the following:

We know what it takes to win cases and can help you investigate the circumstances of your arrest to fight the charges you face to reduce or eliminate any penalties.

Know Your Options for DUI Defenses

If you've been arrested for Driving Under the Influence, you do have options. A DUI conviction can severely impact your professional and personal life and limit your ability to find employment, buy or rent a home or car, or find affordable insurance. Additionally, a suspended license and marred record can stain your reputation among peers. Having a defense attorney in your corner who can explore all avenues to form a solid defense can help you avoid or mitigate negative ramifications of a DUI arrest.

We will question and challenge the following aspects of your DUI arrest:

  • Did the arresting officer have probable cause to pull you over?
  • Were you read your Miranda Warnings?
  • Was your behavior caused by other factors and misinterpreted for inebriation?
  • Can witnesses attest to your sobriety?
  • Were breath, blood, or urine tests administered properly?
  • Were results of any Blood Alcohol Content tests accurate?

If you want to speak with a member of the team at Ronald Dinan & Associates regarding your DUI, you can also contact our 24/7 DUI Help Line.
