DWI Attorney in Houston, Texas

Being arrested for criminal charges can be devastating to your family. It can cost you thousands of dollars in fines and fees, damage you and your family’s reputation and could cost you your job. That’s why it’s vital that you mount the strongest defense possible with a Houston trial lawyer who knows how to fight.

Houston Trial Lawyers Who Fight DWI Charges

When you are pulled over on suspicion of DWI, you have a 95% chance of being arrested when you step out of the car. However, the Houston trial lawyers and Gary Trichter, the DWI Specialist by the National College for DUI Defense, at Trichter & LeGrand can try to get you a favorable outcome from this unfortunate event.

Gary Trichter is a DWI Specialist by the NCDD who has been defending Texans concerned with preserving their valuable reputations since 1980. He co-authored the textbook Texas Drunk Driving Law, and has authored or co-authored 46 legal and aviation articles. Leslie LeGrand is a former Assistant District Attorney, Felony Prosecutor, Harris County and Assistant District Attorney, Juvenile Prosecutor, 315th District Court as well as Chief Misdemeanor Prosecutor in County Criminal Court.

Gary is one of only four board-certified DWI Specialist attorneys in Texas which means his certifications come from the National College for DUI Defense, the sole entity approved by the American Bar Association to issue this designation. The Texas Bar Association has no board certification in DWI Defense, but recognizes the ABA’s  DWI board certification. In addition, Gary has spoken at more than 300 seminars on criminal defense and DWI and they have taught lawyers, judges and prosecutors about various aspects of DWI defense law.

Boating While Intoxicated

Boating while intoxicated (BWI) in Texas is a serious charge. According to the State of Texas, BWI or Boating While Intoxicated in Texas is when (a) A person commits an offense if the person is intoxicated while operating a watercraft. (b) Except as provided by Section 49.09, an offense under this section is a Class B misdemeanor, with a minimum term of confinement of 72 hours.

It’s always best to be a responsible captain as an owner and operator of  watercraft in Texas. Don’t over indulge on alcohol while enjoying yourself on Texas waters. Always wear a life vest and keep plenty on board for every passenger. And, if you’re going to treat guests on your boat, don’t drink.

The Houston trial lawyers at Trichter & LeGrand have years of experience with Texas boating laws on alcohol in Houston, Conroe and Livingston. A BWI arrest can damage your valuable reputation the same way that a DWI or DUI arrest can.
