A DUI Attorney Will Investigate the Circumstances Behind Your Traffic Stop

For some reason, you were stopped by the police while driving. Law enforcement agents are expected to be able to state what that reason for the traffic stop was. Were you weaving unsafely between lanes? Did you roll through a stop sign? Or did you simply have a “look” about you that made a police officer suspect you as a possible impaired driver? When we defend people charged with DWI in North Carolina, we insist that the state meet its full burden of proving that there was a justifiable reason – not just a pretext – for the traffic stop.

DWI Defense Involves Examining All Procedures of the NC DWI Arrest

In support of DWI criminal charges, a Charlotte or Concord, North Carolina police officer collects various types of evidence. Challenging the arrest is not only a matter of challenging field sobriety tests such as the breath test or field sobriety tests designed to measure coordination. Other aspects of the arrest are worthy of investigation – including an examination into what you were told, and when. As a certified Intoxilyzer 5000 instructor and an attorney with more than 10 years of experience, NC DWI defense lawyer Bill Powers can examine the accuracy of Breathalyzer or Intoxilyzer results as well as coordination tests and radar guns.

Challenging NC Field Sobriety Tests: The Validity of Coordination and Intoxilyzer Test Results

Challenging field sobriety tests sometimes takes the form of appealing to the sensibility of a jury with regard to a coordination test. For example, if a person was unable to stand on one leg for thirty seconds, does that verify being impaired? Many other explanations are often reasonable, including obesity, knee problems, fatigue, distraction by cars zipping by, and simple nervousness.

The DWI defense lawyers of Powers McCartan insist that the state meet its responsibility to justify the use of the results of the Intoxilyzer test if it is going to penalize the person severely by taking away his/her driver’s license or sending him/her to jail.The Intoxilyzer results are often the central piece of evidence used in a Mecklenburg County or Cabarrus County DWI prosecution. DWI defense lawyer Bill Powers realized how important it was to fully understand the workings of this machine if he planned on challenging field sobriety tests with full understanding, so he obtained training and became certified in its use and instruction.He has delivered lectures and seminars to other DWI defense lawyers on the subject of why the Intoxilyzer results might sometimes be unreliable. For example, a machine may have been improperly maintained or may not have been calibrated prior to its use at the time of a DWI defendant’s arrest.

Consider the following:

  • DWI cases are complicated and the fact patterns are intricate
  • The penalties even in the best-case scenario tend to be harsh and there is a substantial level of disdain for the offense itself.
  • We are here to help. We offer a free, confidential consultation. Waiting to retain counsel is simply not a good idea.
