How Our Legal Team Can Help You

After police have stopped an individual on suspicion of DWI, they may administer field sobriety tests to gain evidence against the driver. From there, they may request that you submit to a breath or blood test. While these tests are supposed to provide accurate results, they are not always administered correctly. That is where our firm comes in.

We can ask crucial questions such as the following to build your defense:

  • Was the officer responsible qualified to administer the breath or blood test?
  • Were there additional challenges or obstacles added to make your test more difficult to pass?
  • Was the evidence presented collected in accordance with the law?
  • Did the police officer have probable cause for the stop?
  • Was proper procedure followed throughout the process?
  • Did the officer calibrate the breathalyzer correctly?

Just because an officer arrested you after your breath or blood test does not mean your case is lost. Our DWI lawyers in Nassau County are former prosecutor with decades of collective experience. We know how to challenge these tests and ensure the evidence against wasn't gathered unfairly.
