Katy DWI Lawyer &
Criminal Defense Attorney

Most of Katy falls within Harris County — DWI arrests there go to Harris County Criminal Courts at Law in downtown Houston. Parts of Katy in Fort Bend County go to Fort Bend County Courts at Law in Richmond. The small Waller County portion uses Waller County District Court in Hempstead. Herman practices in all three and handles the court appearances in whichever jurisdiction applies to your arrest. A Katy DWI lawyer who knows all three courthouses saves clients from having to explain their case twice.

In many cases yes — for misdemeanor DWI charges, Herman can appear on your behalf so you do not need to miss work or travel to the courthouse. He handles the arraignment, pre-trial hearings, and negotiations with the prosecutor while you stay informed through regular updates. Trial preparation involves more of your time, but most Katy DWI cases are resolved before trial. That's one advantage of hiring a Katy DWI lawyer who handles the paperwork and negotiations directly.

Regardless of where in Katy you were arrested, the ALR license suspension process runs through the Texas Department of Public Safety — not the local court. You have 15 days from the date of arrest to request an ALR hearing. Herman immediately requests your hearing to preserve your right to contest the suspension, often arguing the stop was unlawful, the test was improperly administered, or the evidence is insufficient to support suspension. A Katy DWI lawyer who moves quickly on that filing protects your ability to drive while the criminal case is pending.

Yes. The I-10 West corridor through Katy is one of the most heavily patrolled stretches of highway in the greater Houston area, particularly on weekend nights and during special DWI enforcement campaigns. Texas DPS troopers, Harris County Constables, and Katy Police all run enforcement operations in this corridor. Herman is familiar with the specific patrol patterns, checkpoints, and officer practices in the Katy area and uses that knowledge in defense strategies. Recognizing those patrol patterns is part of what makes an experienced Katy DWI lawyer effective in this specific corridor.

Prior convictions make negotiation harder, but they do not eliminate defense options. Herman focuses on the evidence in the current case — the stop, the field sobriety tests, the chemical test, and the officer's conduct. A strong challenge to current case evidence can still result in dismissal, reduction, or acquittal regardless of prior history. Prior convictions also make suppression motions more important, since a successful suppression can collapse the state's case entirely. A Katy DWI lawyer who prepares suppression motions carefully gives repeat clients a real chance at a better outcome.

Yes — each county has distinct prosecution practices, court cultures, and judge temperaments. Fort Bend County prosecutors tend to be more conservative in offering diversion or non-conviction outcomes on DWI cases compared to Harris County. Herman has experience in both jurisdictions and tailors his defense strategy to the specific court where your case is pending, rather than using a one-size-fits-all approach. That's why choosing a Katy DWI lawyer with experience in both counties matters more here than in a single-county case.

First — say nothing to police beyond identifying yourself. Second — call Herman Martinez as soon as you are released. Third — do not discuss the case on social media or with anyone except your attorney. Time is critical: the 15-day ALR deadline begins at arrest, surveillance footage gets overwritten, and early attorney involvement produces better outcomes. Herman offers 24-hour emergency availability for DWI arrests throughout the Katy area, day or night, weekday or weekend.

Texas DWI checkpoints are permissible under federal constitutional law but must follow specific procedural requirements. If a checkpoint did not use a neutral, predetermined vehicle selection pattern — or failed to meet publicity and supervisory requirements — the stop may be constitutionally defective. Herman challenges checkpoint procedures when the required protocols were not followed, which can suppress all evidence obtained from the stop.

In Harris County (where most of Katy falls), misdemeanor DWI cases typically resolve in 4–9 months through negotiation or dismissal. Cases that proceed to trial take longer. Fort Bend County cases often move faster on the docket. Herman keeps clients updated throughout the process and works proactively to resolve cases as efficiently as possible while never sacrificing the quality of the defense. A Katy DWI lawyer who communicates proactively keeps clients from feeling like their case has stalled.

A DWI arrest triggers CDL disqualification risk beyond the standard ALR suspension. Federal regulations disqualify CDL holders from operating commercial vehicles for one year after a DWI conviction — even for a first offense in a personal vehicle. A second DWI results in lifetime CDL disqualification. Herman treats CDL protection as a primary goal in every DWI case involving a commercial driver, negotiating to avoid any outcome that triggers federal CDL disqualification.
