New Texas Criminal Laws in 2026: What Changed and How It Could Affect Your Case

As we settle into 2026, Texas has seen dozens of new laws take effect that have meaningful implications for criminal law, law enforcement procedures, and penalties. Many of these changes stem from the 89th Texas Legislature and became effective on January 1, 2026, or late in 2025, and are now fully in force across the state.

For Texans facing criminal charges, understanding these updates is not just helpful — it can be critical to building a strong defense and protecting your rights. Below, we break down some of the most important new laws and criminal law-related shifts that may directly affect your case.

DWI in 2026: When a “Simple” DWI Isn’t So Simple

Texas lawmakers tightened DWI penalties going into 2026 after a rise in alcohol-related crashes across the state.

What that means for you is this: certain facts can now turn what looks like a standard DWI into something much more serious very quickly. Here are the situations that now carry tougher consequences:

• DWI with a child passenger can be charged as a felony instead of a misdemeanor.
• DWI committed in a school zone can also be elevated to a felony.
• A blood alcohol concentration of 0.15 or higher is now charged as a Class A misdemeanor instead of a Class B misdemeanor, which increases possible jail time and fines.
• If a drunk driving crash causes more than one death, the charge can be filed as a first-degree felony, carrying a punishment range of five to 99 years, or even life in prison, plus fines up to $10,000.

Those are not small changes. A case that might have once meant probation or county jail time can now expose someone to prison and a permanent felony record depending on the circumstances.

If you’ve been arrested, the key question becomes whether the State can actually prove the enhancement they are alleging. Was the BAC testing accurate? Was the school zone properly designated? Can they prove the passenger’s age? Are they charging the correct level of offense based on the facts?

Stronger penalties do not eliminate defenses. They simply raise the stakes. And when the stakes are higher, the details matter even more.

If you’ve been charged with DWI in Houston, especially in a case involving enhanced penalties, you need an experienced attorney who understands how to challenge BAC testing, school zone allegations, and felony upgrades.

Arrested and Not a U.S. Citizen? Jail Cooperation Laws Matter

Another major change that took effect January 1, 2026 requires many Texas counties that operate jails to cooperate more closely with federal immigration authorities.

This law does not create a new criminal offense. But it can dramatically change what happens after you are arrested. Under the new requirements:

• County sheriffs must enter into formal cooperation agreements with federal immigration authorities.
• Jail officials may assist in identifying individuals who are not U.S. citizens.
• Immigration holds, also called detainers, may be placed more quickly after booking.

What does that mean for someone facing charges?

If you are not a U.S. citizen and you are arrested, your criminal case may now carry immigration consequences much faster than before. Posting bond does not always mean you go home. You could be transferred to federal custody. A case that might otherwise result in probation could still trigger deportation proceedings.

If immigration status is part of your situation, your defense strategy must account for that from the very beginning. Waiting until a plea offer is on the table is often too late to protect your options.

If your case involves immigration concerns, it’s critical to work with a Houston criminal defense lawyer who understands how criminal charges can affect your status. Greg Tsioros can evaluate your case early and build a strategy designed to protect both your freedom and your future.

Criminal Procedure Updates Now in Effect

In addition to DWI and immigration-related changes, certain procedural updates are now fully in effect as of January 1, 2026. These changes affect how cases move through the system and how evidence is gathered.

One key shift involves the continued expansion of electronic warrant processing. Courts and law enforcement agencies are now authorized to use secure digital systems for:

• Submitting search warrant applications
• Issuing arrest warrants
• Approving blood draw warrants in DWI cases
• Filing sworn affidavits electronically

This means judges can legally review and sign warrants without requiring in-person appearances or paper filings. The legal validity of electronically signed warrants is now clearly recognized under Texas procedure.

When warrants are issued quickly and charges are filed aggressively, early legal representation matters. If you believe a search, arrest, or warrant was improper, speak with Houston criminal defense attorney Greg Tsioros as soon as possible to evaluate your options.

New AI Law in 2026: When Technology Becomes a Crime

Texas passed House Bill 149, called the Texas Responsible Artificial Intelligence Governance Act, and it took effect January 1, 2026. The law sets rules for how artificial intelligence can be used in Texas.

Most of the law deals with regulation and oversight. But some parts matter in criminal cases. The law makes it illegal to use AI to:

• Create fake sexually explicit videos or images of someone
• Produce or share child sexual abuse material
• Build or use AI tools designed to encourage crime or self-harm
• Manipulate people into committing violence or illegal acts
• Use automated systems in ways that result in unlawful discrimination

In simple terms, using AI itself is not a crime. But using it to create fake explicit content, exploit someone, or push someone toward illegal behavior can now clearly cross the line under Texas law.

If a criminal case involves digital manipulation, deep fake content, or AI-generated material, this new law may come into play along with existing criminal charges.

If you are facing allegations involving digital evidence, online activity, or AI-generated content, you need a defense attorney who understands both the technology and the law. Greg Tsioros has the experience to challenge complex digital evidence and protect your rights.

What This Means for You

The legal landscape in Texas continues to shift, with new laws shaping everything from technology regulation and prosecutorial reach to law enforcement authority and immigration cooperation. If you are:

• Facing criminal charges,
• Involved in an ongoing investigation, or
• Concerned about how new statutory changes might affect your rights

It is essential to speak with an experienced criminal defense attorney who is tracking these developments and can advise you on how they apply to your case.

Stay informed, and do not wait until it is too late to understand how these changes could impact the outcome of your legal matter.
