Class A vs. Class B Texas DWI Charges

Understanding the Differences Between Class A and Class B DWI Misdemeanors in Texas

When facing a Driving While Intoxicated (DWI) charge in Texas, it’s critical to understand the distinction between a Class A misdemeanor and a Class B misdemeanor. This seemingly small legal difference can significantly impact your penalties, your driver’s license, and even your freedom.

For those in Galveston County—including the scenic and historic Galveston Island—and Harris County, including League City and Friendswood, this post breaks down these classifications, explains what each entails, and highlights the importance of proper legal representation.

The Legal Basics of DWI in Texas

Under Texas law, driving while intoxicated means operating a vehicle with a Blood Alcohol Concentration (BAC) of 0.08 percent or higher—or being impaired by drugs or alcohol. Texas law prohibits drivers from operating a vehicle if they have consumed a drink containing alcohol beyond the legal limit. It is a crime to drive under the influence of alcohol or drugs in Texas. DWI laws also apply to boating, making it illegal to operate a boat while impaired. Drivers of any age can be charged with DWI, but those under the legal drinking age face additional penalties. Breaking DWI laws can result in severe legal consequences. A combination of drugs and alcohol, even if each alone would not exceed the legal limit, is also illegal and can result in a DWI charge. However, not all DWIs are treated equally. The classification of your offense hinges on factors like your BAC at the time of arrest, whether it’s your first offense, and the circumstances of the incident. Additionally, carrying an open container of alcohol in your vehicle is illegal in Texas, which can further complicate a DWI case.

The two most common classifications for first-time DWI offenses are Class A misdemeanor DWI and Class B misdemeanor DWI. Here’s how they differ:

Class B Misdemeanor DWI

For most first-time DWI offenders, the charge typically starts as a Class B misdemeanor. Here’s what establishes the offense:

• A BAC of 0.08 percent or more but less than 0.15 percent.

• Driving under the influence but without circumstances that elevate it to a Class A offense.

• Drivers suspected of a Class B DWI are typically arrested at the scene and taken into custody for further testing and processing.

Penalties for a Class B DWI

If convicted, the penalties for a Class B misdemeanor DWI in Texas include:

• Fines: Up to $2,000

• Jail time: Minimum of three days, up to six months

• Driver’s license suspension: 90 days to one year. License suspensions can range from 180 days to 2 years, depending on prior offenses.

If a driver refuses to take a chemical test, their license may be automatically suspended, regardless of the outcome of the DWI case. The results of the test are a key factor in determining the classification and penalties for a DWI.

A first-time Class B DWI may seem straightforward, but it can still significantly disrupt your life. That’s why effective legal counsel is vital to challenge the evidence or reach a favorable plea agreement.

Class A Misdemeanor DWI

Your case escalates to a Class A misdemeanor DWI if your BAC exceeds 0.15 percent or under other aggravating circumstances. This higher classification doesn’t just increase the penalties—it also marks your record in a much more serious way. The length of jail sentences and license suspensions also increases with the severity of the offense.

Penalties for a Class A DWI

The consequences of being convicted of a Class A DWI are substantial:

• Fines: Up to $4,000

• Jail time: 30 days to one year in county jail. In cases involving aggravating factors or repeat offenses, the maximum jail sentence can extend up to five years.

• Driver’s license suspension: 180 days to two years. The penalties for DWI increase with each subsequent conviction.

Class A DWIs are deemed significantly more severe due to the higher likelihood of impaired driving causing harm. Courts often hold offenders to stricter standards, requiring experienced legal intervention to handle these cases.

Why Blood Alcohol Content (BAC) Matters

The critical distinction between these two classifications boils down to BAC levels. Texas DWI laws apply to any person found operating a vehicle with a BAC above the legal limit. Why does this matter so much? Put simply, higher BAC levels correlate to greater impairment, which increases the risk of accidents, injuries, and fatalities.

BAC Testing and Legal Challenges

Law enforcement often uses tools like breathalyzers or blood tests to determine your BAC. However, these methods are not infallible. Equipment malfunctions, improper testing procedures, and even physiological conditions can lead to inaccurate readings.

Should the prosecution attempt to elevate your offense based on BAC, your defense attorney can challenge the validity of these tests. This is particularly important in cases where the evidence might push the charge from a Class B to a Class A offense.

Case in Point: Pho Van Do v. State

A recent decision by the Texas 14th District Court of Appeals serves as a stark example of why understanding the distinction between Class A and Class B DWIs matters. The history of DWI law classifications in Texas, which has evolved over time to address changing legal and social concerns, provides important context for this case.

The Situation

The defendant, in this case, was charged with a DWI in January 2017. The charging document alleged that the defendant’s BAC was “at least 0.15 percent,” automatically categorizing the offense as a Class A misdemeanor. However, this fact was never presented to the jury—a significant procedural misstep.

Ruling and Impact

The jury convicted the defendant of a general DWI offense. Nonetheless, at sentencing, the judge improperly treated it as a Class A misdemeanor based on the BAC level. The judge claimed the BAC was a “punishment element,” rather than a key element of the offense itself. However, the appellate court ruled this incorrect, emphasizing that BAC is central to determining the offense’s classification.

The defendant’s one-year sentence—appropriate for a Class A misdemeanor—was voided. In more severe DWI convictions, especially for repeat offenders or felony cases, the penalties can include longer prison sentences rather than just jail time. The case highlighted not only the severity of ensuring the accurate handling of legal distinctions but also the critical role of thorough legal representation in defending one’s rights.

The Real-World Impact of DWI Convictions

Collateral Consequences

Beyond jail time, fines, and license suspensions, DWI convictions carry extensive collateral consequences. Whether classified as a Class A or Class B misdemeanor, these offenses can:

• Raise insurance premiums dramatically

• Impact employment opportunities, especially in roles requiring driving or background checks

• Create permanent public criminal records

• Add points to the driving record for any driver convicted of a DUI or DWI.

Probation may be available as an alternative to jail time for some DWI offenders, allowing them to remain in the community under court-ordered supervision. Participation in an alcohol education or treatment program may also be required as part of sentencing, supporting rehabilitation and reducing repeat offenses. In certain cases, installation of an ignition interlock device is mandatory for DWI convictions, restricting vehicle operation unless the driver is sober. A skilled lawyer can serve clients by advocating for reduced penalties, alternative sentencing options like probation, and ensuring the best possible outcome.

Additionally, for those with professional or commercial licenses, a DWI conviction—even at the Class B level—can jeopardize their ability to work. For instance, CDL holders risk losing job certifications with even a first-time intoxication offense.

The Importance of Hiring a Skilled DWI Lawyer

Because these cases involve technical legal elements—like BAC results and procedural protocols—having a seasoned DWI defense lawyer is paramount. A knowledgeable attorney can:

• Scrutinize the accuracy of BAC tests

• Challenge law enforcement reports for inconsistencies

• Ensure proper procedural adherence by the prosecution and court

• Negotiate plea deals to reduce the severity of charges or penalties

• Advocate for alternatives like ignition interlock devices, which may be required under certain circumstances after a DWI conviction.

• Advise clients on how to formally request participation in the Ignition Interlock Program to regain limited driving privileges during a license suspension.

• Scrutinize the accuracy of BAC tests

• Challenge law enforcement reports for inconsistencies

• Ensure proper procedural adherence by the prosecution and court

• Negotiate plea deals to reduce the severity of charges or penalties

If you’re facing a DWI, don’t assume the penalties are set in stone. With the right legal strategy, outcomes can often shift in your favor.
