A First-Time DWI Charge Is Serious, But It Isn’t Hopeless.

A first-time DWI arrest hits hard. You may have questions regarding your license, criminal record, and current employment. If this is your first encounter with the criminal justice system, this uncertainty is understandable.

What matters most right now: you’ve been arrested, not convicted. The State must prove every element of the offense beyond a reasonable doubt, and that burden doesn’t shrink because the charge feels serious and overwhelming.

At Denuna & Westbrook, PLLC, we represent individuals facing first-time DWI charges throughout Houston and the Gulf Coast region. In every case, we examine the evidence, challenge weaknesses in the State’s case, and pursue all options for the best outcome.

What a First-Time DWI Charge Means in Texas

A first-time DWI with no serious accident and no passenger under fifteen is charged as a Class B misdemeanor when the alleged BAC is below 0.15, carrying a punishment range of up to 180 days in jail and a maximum fine of $2,000. If the State alleges a BAC of 0.15 or higher, the charge can be elevated to a Class A misdemeanor, with a punishment range of up to one year in jail and a maximum fine of $4,000.

A Class B charge also carries potential consequences beyond jail and fines:

• Probation with reporting requirements
• Driver’s license suspension
• Ignition interlock device requirements
• Surcharges and additional fees

Which of these apply, and to what degree, depends on how the case is charged and resolved.

Ignition Interlock Requirements in Texas DWI Cases

After a DWI arrest, the court may require you to install an ignition interlock device as a condition of bond or probation.

For a Class B misdemeanor, where the alleged BAC is below 0.15, installation is not mandatory, but the court has discretion to order one. For a Class A misdemeanor, where the alleged BAC is 0.15 or higher, an ignition interlock is mandatory under Texas law.

In cases involving a blood draw, lab results may not be available for weeks after the arrest. If those results come back showing a BAC of 0.15 or higher, a case originally filed as a Class B misdemeanor can be enhanced and recharged as a Class A. When this happens, ignition interlock requirements that weren’t part of the original bond conditions may become mandatory.

Additional State Fines Exclusive to DWI Cases

Unlike other criminal charges in Texas, a DWI conviction also triggers a mandatory state fine under Texas Transportation Code Section 709.001, separate from whatever fine the court imposes.

For a first-time conviction, those amounts are:

• Standard first-time DWI: $3,000
• First-time DWI involving any accident: $4,500
• First-time DWI with a BAC of 0.15 or higher: $6,000

These fines stack on top of court costs, probation fees, ignition interlock expenses, and any judge-ordered fine. Whether the mandatory fine applies can turn on how the case is resolved, which should be discussed with an attorney early in the process.

Two Cases, One Arrest: Criminal Court and ALR Proceeding

A DWI arrest doesn’t just create a criminal case. It creates two separate proceedings that run on different tracks.

The criminal case is handled by the district attorney’s office or county attorney’s office, depending on the county prosecuting the case. The Administrative License Revocation (ALR) case is a separate proceeding brought by the Texas Department of Public Safety, focused entirely on whether your driver’s license gets suspended. Even if the criminal case is dismissed, you may still face a license suspension connected to the arrest itself, which is why the ALR process deserves immediate attention from the start.

The ALR process moves quickly, but the deadline depends on how the investigation unfolded. In cases involving a breath test failure, breath test refusal, or blood test refusal where a warrant was obtained, the officer issues a Notice of Suspension at the scene. You have 15 days from that date to request a hearing. Miss that window and the suspension takes effect on the 40th day.

The one exception involves a consensual blood draw. When a person voluntarily consents to a blood draw rather than refusing, no Notice of Suspension is issued at the scene. The clock doesn’t start until DPS receives the lab results showing a BAC of 0.08 or higher and mails a notice to the address on the driver’s license. From that mailed notice, you have 20 days to request a hearing. Because the notice can arrive weeks after the arrest and goes to whatever address DPS has on file, this deadline is easy to miss.

CDL Holders Face a Higher Standard and Greater Consequences

For drivers holding a Commercial Driver’s License, a DWI arrest in a personal vehicle creates additional problems and consequences.

A Lower BAC Threshold

The legal BAC limit for CDL holders operating a commercial vehicle is 0.04%, exactly half the standard 0.08% threshold that applies to non-commercial drivers. A reading between 0.04% and 0.08% won’t result in a standard DWI charge, but it can still trigger CDL disqualification. In near-threshold cases, the forensic science behind the testing becomes especially important. A marginal reading carries significant uncertainty, and challenging the BAC deserves close examination.

The type of vehicle being driven at the time of arrest doesn't matter. A DWI conviction in a personal vehicle triggers the same CDL disqualification as one involving a commercial vehicle.

DWI and CDL Disqualification

Under Texas Transportation Code Section 522.081, a first-time DWI conviction results in a minimum one-year CDL disqualification. If the driver was transporting hazardous materials at the time, that extends to three years. A second conviction, at any point in the driver’s lifetime, results in a lifetime CDL disqualification, with only a narrow reinstatement path available after ten years in certain cases.

There is no occupational CDL available during the disqualification period. A standard license suspension allows limited driving privileges for work and household essentials. CDL disqualification carries no such relief. A commercial driver whose CDL is disqualified cannot legally work in any commercial driving capacity until the period ends.

A deferred sentence, a guilty plea, or a no-contest plea all count as a conviction for CDL disqualification purposes. The criminal outcome and the CDL consequence don’t always track the same way, and that distinction matters when evaluating how to resolve the case.

The ALR Deadline Is the Same, But the Stakes Are Higher

The 15-day ALR deadline applies to CDL holders just like other drivers charged with DWI. But missing the deadline carries far greater consequences for a commercial driver.

A standard driver who misses the ALR deadline faces a license suspension that may be addressed through an Occupational Driver’s License. A CDL holder, on the other hand, faces disqualification with no occupational CDL available. There is no limited driving relief during a CDL disqualification period. For a commercial driver, that means no work, no income, and no alternative until the disqualification period ends.

The ALR hearing also carries strategic value beyond the license itself. It compels the arresting officer to testify under oath early in the case, before the criminal proceedings develop, creating a sworn record that can be used throughout the defense.

For any CDL holder facing a DWI arrest, acting immediately isn’t a suggestion; it’s a necessity.

How the State Tries to Prove a First-Time DWI

Under Texas Penal Code Section 49.04, the State must prove that a person operated a motor vehicle in a public place while intoxicated. Texas law defines intoxication three ways, each caused by alcohol, drugs, controlled substances, or any combination:

• Loss of normal mental faculties
• Loss of normal physical faculties
• A blood alcohol concentration of 0.08 or greater

It’s easy to assume the case begins and ends with a breath or blood test number. That’s not how prosecutors always approach it. Officer observations, field sobriety tests, video footage, and witness accounts can become the centerpiece of the State’s case with or without a test result. A result below 0.08 doesn’t close the door on a prosecution, and neither does the absence of a test entirely.

That’s especially true in drug-related DWI cases, where there’s no numerical threshold to point to. Prosecutors in those cases rely on observations, field testing, and Drug Recognition Expert testimony to argue impairment existed at the time of driving.

A test result above 0.08 isn’t the end of the analysis either. Questions about how the sample was collected, whether the equipment was properly maintained, how the breath or blood testing was performed, and whether the results were correctly interpreted can all factor into the reliability of that number.

Challenging the Evidence in a First-Time DWI Case

Reviewing all of the evidence, not just the arrest report, is where a first-time DWI case is won or lost. Three areas deserve close attention in every case.

Traffic Stops and Welfare Checks

The traffic stop is the first issue worth examining, but the interaction between law enforcement and a driver doesn’t always begin with a moving violation. Many DWI arrests start with a welfare check, where an officer approaches a vehicle that is stopped, idling, or parked, usually after someone reports a driver asleep or slumped over at the wheel. Whether the case begins with a traffic stop or a welfare check, law enforcement needs legal justification for the interaction. If that justification didn’t exist, or the encounter didn’t comply with constitutional requirements, the evidence that followed may be subject to challenge.

Standardized Field Sobriety Tests (SFSTs)

Field sobriety tests are treated as objective proof of intoxication, but performance can be influenced by fatigue, nervousness, medical conditions, physical limitations, uneven surfaces, weather, and how the instructions were given. The conditions under which those tests were administered matter as much as the results.

Blood and Breath Testing

Blood and breath testing isn’t beyond scrutiny. Collection procedures, chain-of-custody issues, calibration records, laboratory analysis, and how results are interpreted all factor into whether that evidence holds up.

Can a First-Time DWI Be Dismissed or Reduced?

Dismissal and reduction are realistic outcomes in first-time DWI cases, and they happen more than people expect. Whether either is available depends on the evidence, the legal issues uncovered during the investigation, and the county handling the case.

Many Texas counties offer diversion or pretrial intervention programs for qualifying first-time cases. When it’s the right fit, diversion can be an effective way to avoid a conviction. But it shouldn’t be the assumed destination before the evidence has been evaluated. The strength of the State’s case should drive that conversation, not the assumption that a conviction is automatic.

Minors Under 21 and Texas Zero Tolerance

Texas law treats drivers under 21 differently. The standards are stricter, the consequences are real, and the clock starts running shortly after the arrest.

DUI vs. DWI for Minors

For adult drivers, the legal threshold for intoxication is a BAC of 0.08 or higher. For drivers under 21, there is no threshold. Under Texas Alcoholic Beverage Code Section 106.041, any detectable amount of alcohol in a minor’s system while driving is enough for a criminal charge. This is a separate offense called Driving Under the Influence by a Minor, commonly referred to as a DUI. A first-time DUI is a Class C misdemeanor, carrying fines up to $500, community service, an alcohol awareness course, and a license suspension of 60 to 180 days.

If a minor’s BAC reaches 0.08 or higher, the charge becomes a standard adult DWI under Texas Penal Code Section 49.04, a Class B misdemeanor with the same punishment range, ALR consequences, and long-term record implications as any adult facing the same charge. In some cases, a minor can face both charges simultaneously.

ALR Deadlines Apply to Minors Too

The 15-day ALR deadline applies to minors just as it does to adults. From the date the Notice of Suspension is received, a minor has 15 days to request an ALR hearing to challenge the license suspension. Miss that window and the suspension takes effect automatically on the 40th day. Parents and families often don’t realize this clock is running from the night of the arrest.

The Record Consequences Are Real

A DUI or DWI conviction doesn’t disappear when a minor turns 21. It stays on the record permanently unless addressed, and it can surface in college applications, scholarship reviews, employment background checks, professional licensing, and housing. For a young person at the beginning of their academic or professional life, how the case is resolved can carry consequences well beyond the courtroom.

Your Criminal Record After a First-Time DWI

A DWI conviction doesn’t just close a court case. It follows a person into job applications, professional licensing, insurance, and more. And in Texas, convictions stack.

A second DWI is automatically enhanced to a Class A misdemeanor, carrying a mandatory minimum of three days in jail even when probation is granted. A third becomes a Third-Degree Felony, with a punishment range of two to ten years in prison. The progression doesn’t stop there. A child passenger, a serious accident, or a fatality can push any DWI into felony territory regardless of prior history. What starts as a misdemeanor can escalate quickly, and each prior conviction makes the next case more serious.

DWI convictions can’t be expunged, but a first-time conviction doesn’t have to follow you forever. Certain first-time offenses may qualify for nondisclosure if there was no accident involving another person and the BAC was below 0.15. Waiting periods apply, and the court has discretion, but when the conditions are met, a nondisclosure seals the record from most public background checks. Deferred adjudication, when available and appropriate, offers a separate and generally more accessible path to nondisclosure with its own requirements. Either way, how a first-time DWI is resolved determines which options remain open down the road.

Frequently Asked Questions — First-Time DWI in Texas

Will I go to jail for a first-time DWI?

Jail is possible but not automatic. The outcome depends on the allegations, the evidence, the jurisdiction, and how the case is resolved.

Will I lose my driver’s license?

You may face a suspension, but you have a limited window to request an ALR hearing and challenge it. Acting quickly matters.

Can a first-time DWI be dismissed?

Some are. Whether dismissal is realistic depends on the facts, the evidence, and any legal issues in the State’s case.

Will I have to install an ignition interlock device?

It depends on how the case is charged. A Class B misdemeanor gives the court discretion, though many counties order one. A Class A misdemeanor, where the alleged BAC is 0.15 or higher, makes it mandatory. If the State enhances the charge from a Class B to a Class A after blood test results come in, interlock requirements can change mid-case.

Should I hire a lawyer for a first-time DWI?

A DWI arrest reaches further than a single court date. Early representation helps protect your driving privileges, preserve evidence, and make sure nothing is missed before the case moves forward.
