Early Strategy
A DWI Case Moves Quickly
When someone is arrested for DWI, immediate concerns often include jail release, driver’s license issues, court dates, and the long-term effect on employment and reputation. Early legal guidance can make an important difference in how the case is handled. The earlier the defense begins, the more opportunity there is to protect your license, preserve evidence, and address problems before they become harder to fix.
Drinking and Driving Is Not the Same as DWI
Having a drink before driving is not automatically a DWI. The State still has to prove intoxication. Our job is to make the State prove it.
Protect Your License
DWI arrests can trigger separate license-related deadlines and hearings. Prompt attention helps preserve options and avoid preventable mistakes.
Texas DWI Charges Can Become More Serious
A first DWI in Texas is generally charged as a Class B misdemeanor, but the level of the offense can increase depending on the circumstances. For example, a DWI involving an alcohol concentration of 0.15 or more at the time the specimen is analyzed is a Class A misdemeanor. A DWI with a passenger younger than 15 is a state jail felony, and prior DWI convictions can elevate a subsequent DWI to a more serious offense.
The charge level is only one part of the case. The defense should also examine how the traffic stop began, what the officer observed, how field sobriety testing was conducted, whether breath or blood evidence was lawfully obtained, and whether the State can reliably prove intoxication.
Facing a First, Repeat, or Felony DWI?
Texas DWI charges can become more serious depending on prior convictions, alcohol concentration, the presence of a child passenger, and other circumstances.
Your Driver’s License Is a Separate Issue
A DWI arrest can also trigger an Administrative License Revocation (ALR) case that is separate from the criminal prosecution. A person who wants to contest an ALR suspension generally must request a hearing within 15 days. If the hearing is timely requested, the suspension is stayed until the administrative law judge issues a final decision.
Because the ALR process moves independently from the criminal case, that short deadline is one reason early legal advice matters.
HOW DWI CASES ARE DEFENDED
Building a DWI Defense From the Evidence
A DWI arrest does not mean the State can prove intoxication. The defense starts by examining how the investigation began, what the officer actually observed, how sobriety testing was conducted, and whether breath or blood evidence can be trusted and legally used.
The defense strategy should be built around the actual evidence in the case, not simply the arrest report or the number reported by a breath or blood test.
