When one is facing a charge of DWI, one can go to trial or engage in plea bargaining with the state. Deciding to negotiate a guilty plea, just like going to trial, carries with it its own set of potential advantages and disadvantages. If you plead guilty, the state can use that offense against you if you are charged again in the future for another DWI, unless you can show that your plea was improperly obtained. One driver from St. Tammany attempted to defeat his guilty plea by arguing that he did not knowingly and voluntarily waive his rights. The Louisiana Court of Appeal was unpersuaded, though, since the evidence in the case showed a knowing and voluntary plea, even though the trial judge did not obtain an express statement of waiver of rights from the driver in open court.
On Aug. 31, 2010, a Louisiana State Trooper reported to the scene of a single-car accident on US 190 in St. Tammany Parish. In investigating the vehicle, the trooper found a bottle and a cup that smelled of alcohol. At a nearby hospital, the trooper performed sobriety tests, which the driver, Thomas Mason, III, failed. A blood-alcohol test yielded a result of 0.17. The driver had alcohol, Ambien, Xanax, and hydrocodone in his system.
