Facing Felony DWI Charges in Galveston County?

Being arrested for a felony DWI in Galveston County can leave you feeling uncertain about what comes next. Many people assume a DWI is always a misdemeanor, but Texas law allows certain circumstances to elevate the charge to a felony offense with much more serious consequences. A felony DWI can affect your freedom, your employment, and your future opportunities.

Prosecutors in Galveston County and throughout the Houston area often take felony DWI cases seriously, particularly when prior convictions or aggravating factors are involved. Understanding how Texas law applies and what defenses may be available is critical if you are facing these allegations.

We represent individuals accused of felony DWI in Galveston County and across Houston. Our role is to carefully evaluate the facts, examine the legality of the stop and arrest, and challenge the prosecution’s evidence wherever possible. Every felony DWI case is different, and early action can make a significant difference in the outcome.

What Makes A DWI A Felony In Texas

Under Texas Penal Code §49.04, driving while intoxicated is generally charged as a misdemeanor for first-time offenders. However, Texas law allows a DWI to become a felony under several circumstances.

One of the most common reasons for felony DWI charges is prior convictions. Under Texas Penal Code §49.09(b)(2), a third DWI offense is charged as a third-degree felony. Texas does not impose a time limit on prior DWI convictions. Even older convictions may still be used to enhance a new charge.

Other situations that can lead to felony DWI charges include:

  • Intoxication assault under Texas Penal Code §49.07
  • Intoxication manslaughter under Texas Penal Code §49.08
  • DWI with a child passenger under Texas Penal Code §49.045
  • Prior felony DWI conviction enhancing a new offense

These felony charges carry significantly higher penalties and more long-term consequences than misdemeanor DWIs.

Penalties For Felony DWI In Galveston County

A felony DWI conviction in Texas carries severe penalties. A third-degree felony DWI under Texas Penal Code §12.34 may include:

  • Two to ten years in prison
  • Up to a $10,000 fine
  • Driver’s license suspension
  • Mandatory ignition interlock device
  • Probation in some cases

In addition to these penalties, a felony conviction can create lasting consequences. Many individuals face challenges related to employment, housing, and professional licensing. A felony record can also affect immigration status and firearm rights.

Galveston County prosecutors often review prior criminal history, blood alcohol levels, and whether an accident occurred when evaluating felony DWI cases. These factors can influence how aggressively the case is pursued.

How Texas Defines Intoxication

Texas Penal Code §49.01 defines intoxication in two ways. A person is considered intoxicated if they:

  • Do not have normal use of mental or physical faculties due to alcohol or drugs
  • Have a blood alcohol concentration of 0.08 or higher

This means prosecutors do not always need a chemical test result. Officers may rely on observations, field sobriety tests, and other evidence to argue intoxication.

How Felony DWI Cases Are Investigated

Felony DWI cases typically involve multiple forms of evidence. Law enforcement officers often collect:

  • Officer observations
  • Field sobriety test results
  • Breath or blood test results
  • Body camera footage
  • Witness statements
  • Accident reports

In cases involving prior convictions, prosecutors must also prove the prior offenses. This often requires certified court records and identification linking the defendant to those convictions.

Common Defenses To Felony DWI Charges

Every felony DWI case is unique. However, several defense strategies are frequently applied in Galveston County felony DWI cases.

Challenging The Traffic Stop

Law enforcement must have reasonable suspicion to initiate a traffic stop. If the officer lacked a lawful basis, evidence obtained afterward may be challenged. Dash camera footage, dispatch records, and officer reports often help determine whether the stop was valid.

Challenging Field Sobriety Tests

Field sobriety tests are not always reliable. Many factors can affect performance, including:

  • Medical conditions
  • Fatigue
  • Weather conditions
  • Uneven surfaces
  • Improper instructions

We review whether officers followed proper testing procedures and whether the results are reliable.

Challenging Breath And Blood Tests

Chemical tests must follow strict procedures. Potential issues may include:

  • Improper calibration of breath machines
  • Improper handling of blood samples
  • Chain of custody issues
  • Improper warrants for blood draws

Scientific and procedural errors can weaken the prosecution’s case.

Challenging Prior Convictions

In felony DWI cases based on prior convictions, prosecutors must prove those convictions beyond a reasonable doubt. Errors in documentation or identification may create opportunities to challenge the enhancement.

Administrative License Revocation Hearings

After a DWI arrest, the Texas Department of Public Safety may attempt to suspend your license. Under Texas Transportation Code §524.011, you typically have 15 days to request a hearing. If you fail to request a hearing, your license may be automatically suspended.

An Administrative License Revocation hearing provides an opportunity to challenge the suspension and obtain valuable information about the prosecution’s case.

The Felony DWI Court Process In Galveston County

Felony DWI cases usually involve several steps:

  • Arrest and booking
  • Magistrate hearing
  • Grand jury indictment
  • Arraignment
  • Pretrial hearings
  • Negotiations or trial

Each stage provides opportunities to challenge the case and protect your rights.

Long-Term Consequences Of A Felony DWI Conviction

A felony DWI conviction can impact your life beyond court penalties. Many individuals face:

  • Difficulty finding employment
  • Professional licensing issues
  • Housing limitations
  • Increased insurance rates
  • Permanent criminal record

Texas law provides limited options for sealing felony DWI convictions. This makes defending the case aggressively from the beginning especially important.

Why Early Legal Representation Matters

The earlier we become involved, the more opportunities exist to challenge the case. Early representation allows us to:

  • Preserve evidence
  • Interview witnesses
  • Review police conduct
  • Challenge testing procedures
  • Develop defense strategies

Prompt legal guidance can significantly influence the outcome.
