What Is the Penalty for First Offense DWI in Texas?

You were arrested for DWI. Maybe it was a Friday night traffic stop. Maybe it was a checkpoint. Maybe you had two drinks at dinner and genuinely did not believe you were impaired. However it happened, you are now staring at a charge that carries real consequences — and you are trying to figure out exactly how serious this is.

The answer is: more serious than most people expect, even for a first offense with no prior criminal history. Texas has some of the toughest DWI laws in the country. The penalties are not limited to what a judge sentences you to in court — they extend into your finances, your driving privileges, your career, your professional licenses, and your permanent record in ways that continue affecting your life long after the case closes.

This guide breaks down every penalty associated with a first offense DWI in Texas — the statutory penalties, the hidden costs, the collateral consequences, and the aggravating factors that can turn a misdemeanor into something far more serious. Understanding exactly what you are facing is the first step toward fighting back.

How Texas Law Defines DWI

Before addressing penalties, it helps to understand precisely what Texas law considers a DWI. Under Texas Penal Code Section 49.04, a person commits Driving While Intoxicated when they operate a motor vehicle in a public place while intoxicated. Texas law defines intoxication in two ways: having a blood or breath alcohol concentration (BAC) of 0.08 or higher, or not having the normal use of mental or physical faculties due to the introduction of alcohol, a controlled substance, a drug, or any combination of these.

That second definition — loss of normal use of faculties — is critically important because it means the state can pursue a DWI conviction even if your BAC was below 0.08. If an officer observes signs of impairment and you fail field sobriety tests, the prosecution can argue you were legally intoxicated regardless of your BAC reading. Conversely, a BAC of 0.08 or above creates a legal presumption of intoxication even if you were driving normally.

This distinction matters because it shapes your defense. Whether the state is relying on the per se BAC standard, observable impairment, or both, there are specific and distinct challenges available to an experienced San Antonio DWI defense attorney for each.

First Offense DWI in Texas: The Statutory Penalties

A first offense DWI with no aggravating factors is charged as a Class B Misdemeanor under Texas Penal Code Section 49.04. Here are the penalties the Texas legislature has authorized for this offense.

Jail time. A Class B Misdemeanor DWI carries a minimum of 72 hours in county jail and a maximum of 180 days. The 72-hour minimum is mandatory — a judge cannot sentence you to less than three days behind bars on a standard first offense DWI conviction. In practice, many first-time offenders in Bexar County are sentenced to time served during the initial arrest and booking, or to a period of community supervision (probation) rather than active jail time. However, jail is always on the table, and the specific judge, the facts of your case, and the quality of your legal representation all influence where within that range your sentence falls.

Fines. The maximum fine for a Class B Misdemeanor DWI in Texas is $2,000. Courts also impose court costs and fees on top of this statutory fine — administrative fees, attorney appointment fees if applicable, and other court-assessed costs that can add hundreds of dollars to the total financial burden.

Driver’s license suspension. A first offense DWI conviction triggers a driver’s license suspension ranging from 90 days to one year under Texas Transportation Code Section 521.344. This is the criminal court suspension — separate from the administrative suspension triggered by your arrest, which is handled entirely independently through the Texas Department of Public Safety.

Community supervision (probation). Texas judges frequently sentence first-time DWI offenders to community supervision rather than active incarceration. Standard first offense DWI probation in Texas can last up to two years and typically includes conditions such as regular check-ins with a probation officer, drug and alcohol testing, DWI education classes, and a prohibition on consuming alcohol. Violating any condition of probation can result in the court revoking supervision and imposing the original jail sentence in full. If you are placed on probation for a first offense DWI, take every condition seriously — DWI probation violations are prosecuted aggressively and can land you in jail on a case you thought was behind you.

Ignition interlock device. A judge has discretion to order installation of an ignition interlock device (IID) as a condition of bond, probation, or license reinstatement. An IID requires the driver to provide a breath sample before the vehicle will start and at random intervals while driving. The cost of installation and monthly monitoring — typically $70 to $150 per month — falls entirely on the defendant.

The DPS Administrative License Suspension: A Separate Fight Running Parallel

One of the most misunderstood aspects of Texas DWI law is that there are two completely separate proceedings affecting your driver’s license — the criminal court case and the Texas Department of Public Safety Administrative License Revocation (ALR) process.

When you were arrested for DWI and either failed a breath or blood test showing a BAC of 0.08 or higher, or refused to provide a specimen, the arresting officer confiscated your driver’s license and issued a notice of suspension. That suspension is not contingent on a criminal conviction. The DPS will suspend your license automatically unless you request an ALR hearing within 15 days of your arrest.

That 15-day deadline is absolute. Miss it and you lose your right to contest the administrative suspension, which for a first offense refusal is 180 days and for a first offense failure is 90 days. These suspensions run independently of anything that happens in criminal court — you can have your criminal case dismissed and still lose your license through the ALR process if you failed to request a hearing.

This is one of the most urgent reasons to contact a DWI attorney immediately after an arrest, not days or weeks later. The ALR hearing request must be filed before the deadline, and an attorney can fight the administrative suspension on separate grounds from your criminal defense — challenging whether the officer had reasonable suspicion for the stop, whether proper testing protocols were followed, and whether the results are valid.

After a suspension, you may be eligible for an occupational driver’s license that allows you to drive for work, school, and essential household activities while the full suspension is in effect. Our attorneys handle license reinstatement and occupational license proceedings in addition to the criminal defense case.

The Texas DWI Surcharge: A Hidden Penalty That Hits Every Year

One of the most financially damaging and least publicized consequences of a first offense DWI conviction in Texas is the state’s annual Driver Responsibility Program surcharge — a fee assessed by the DPS every year for three years following a conviction.

For a first offense DWI conviction, the annual surcharge is $1,000 per year for three years, totaling $3,000 in addition to all court fines, fees, and costs. If your BAC was 0.16 or higher at the time of arrest, the annual surcharge doubles to $2,000 per year — $6,000 total over three years.

Failure to pay the annual surcharge results in an additional driver’s license suspension. Many Texans are blindsided by this ongoing financial obligation, which continues hitting their bank account years after they believe the case is fully behind them. When you factor in the surcharge alongside court fines, court costs, attorney fees, increased insurance premiums, and ignition interlock costs, the true financial cost of a first offense DWI conviction routinely exceeds $10,000 — and that is before accounting for any lost income from jail time or license suspension.

When a First DWI Becomes a More Serious Charge

Several aggravating factors can elevate a first offense DWI from a Class B Misdemeanor to a more serious charge with significantly higher penalties. Every one of these factors is a reason to have an attorney working your case from the moment of arrest.

BAC of 0.15 or higher. Under Texas Penal Code Section 49.04(d), a first offense DWI with a BAC of 0.15 or above is charged as a Class A Misdemeanor rather than a Class B. This elevates the maximum jail sentence from 180 days to one year in county jail and the maximum fine from $2,000 to $4,000. The annual DPS surcharge also increases. An attorney who challenges the validity or accuracy of the blood or breath test result is therefore attacking not just the conviction but the charge level itself — potentially the difference between a misdemeanor with a $2,000 fine cap and a more serious misdemeanor with doubled consequences.

Child passenger under 15 years old. If a child under the age of 15 was in the vehicle at the time of the DWI arrest, the charge is enhanced under Texas Penal Code Section 49.045 to a State Jail Felony, regardless of your prior record or BAC level. A state jail felony carries 180 days to two years in a state jail facility and a fine of up to $10,000. This is not a misdemeanor. It is a felony conviction that permanently impacts your record, your rights, and every aspect of your life going forward. If your arrest involved a child passenger, contact an attorney immediately and understand that you are no longer in misdemeanor territory.

Open container in the vehicle. Under Texas Penal Code Section 49.031, if an open container of alcohol was in the passenger area of your vehicle at the time of the DWI arrest, your minimum mandatory jail time increases from 72 hours to six days in county jail — even on a first offense, even on probation.

Accident causing injury. If your DWI arrest arose from an accident in which another person suffered serious bodily injury, you face Intoxication Assault under Texas Penal Code Section 49.07 — a Third Degree Felony carrying two to ten years in state prison and a fine of up to $10,000. If someone died, the charge is Intoxication Manslaughter under Section 49.08 — a Second Degree Felony carrying two to twenty years in state prison. These are not DWI cases that can be negotiated to misdemeanor level without extraordinary circumstances.

The Collateral Consequences Nobody Tells You About

The statutory penalties — jail, fines, suspension — are the consequences written in the law. The collateral consequences are the ones that follow you out of the courtroom and into every corner of your life. For many people, these are actually more damaging than the formal sentence.

Criminal record. A DWI conviction in Texas is a permanent criminal record. It does not automatically disappear after a period of time. It shows up on background checks run by employers, landlords, banks, and professional licensing boards. In Texas, a first offense misdemeanor DWI cannot be expunged if you were convicted — only dismissed charges or not guilty verdicts qualify for expungement. A conviction can only qualify for an Order of Nondisclosure under very limited circumstances. This is why fighting your case — rather than accepting a quick guilty plea — can have permanent consequences for your future that extend decades beyond the court date.

Employment consequences. Many employers conduct criminal background checks and have policies that exclude candidates with DWI convictions, particularly for positions involving driving, security clearances, financial services, healthcare, and working with children. If you hold a Commercial Driver’s License (CDL), a first offense DWI conviction disqualifies you from operating a commercial motor vehicle for one year — effectively ending or severely disrupting a career built around professional driving.

Professional licensing. Nurses, physicians, attorneys, teachers, real estate agents, insurance agents, and many other licensed professionals in Texas are required to report criminal convictions to their licensing boards. A DWI conviction can trigger a board investigation, suspension of licensure, or additional conditions placed on your license to practice. If you hold any professional license, the licensing board consequences of a DWI conviction may be more immediately threatening to your livelihood than the criminal penalties themselves.

Auto insurance. Insurance companies treat a DWI conviction as a major risk factor. Following a conviction, your auto insurance premiums will increase substantially — by hundreds or thousands of dollars per year — and some insurers will drop your policy entirely, forcing you into high-risk insurance pools at dramatically elevated rates. This premium increase typically persists for three to five years or longer.

Immigration consequences. For non-citizens, a DWI conviction can have serious immigration consequences depending on visa status, the specific charge, and prior history. If you are not a U.S. citizen, you must discuss immigration implications with your attorney before accepting any plea agreement.

Military consequences. Active duty military personnel and veterans stationed at Joint Base San Antonio, Fort Sam Houston, Lackland, or Randolph face additional consequences from a civilian DWI conviction, including potential impact on security clearances, military career advancement, and administrative separation proceedings. Our firm handles cases for active duty and veteran clients and understands the dual-track consequences they face.

Can a First Offense DWI Be Dismissed or Reduced in Texas?

Yes — and this is what an aggressive defense strategy makes possible.
A DWI charge is not a conviction. It is an allegation. The state carries the burden of proving every element of the offense beyond a reasonable doubt, and experienced DWI defense attorneys find weaknesses in that proof every day in Bexar County courts.

Common defense strategies in first offense DWI cases include challenging whether the officer had legal justification — reasonable suspicion — to stop your vehicle in the first place. If the stop was unlawful, all evidence gathered after it may be suppressible. This alone can result in dismissal. Defense attorneys also challenge field sobriety tests, which are notoriously unreliable — the National Highway Traffic Safety Administration’s own research shows they have significant error rates even when administered perfectly, and they are rarely administered perfectly. Breathalyzer results can be challenged based on calibration records, maintenance logs, the officer’s certification, and the conditions of the test. Blood test results can be challenged based on the chain of custody, lab procedures, and whether the blood draw was constitutionally obtained.

When a case cannot be dismissed outright, prosecutors in Bexar County sometimes offer plea agreements reducing a DWI to a lesser charge — most commonly Obstruction of a Highway or Failure to Maintain a Single Lane — in cases where the state’s evidence is weak or where specific circumstances support a reduction. These lesser charges do not carry the same collateral consequences as a DWI conviction and may qualify for expungement. Accepting such an agreement is a strategic decision made case by case, weighing the strength of the evidence, the risk of trial, and the specific collateral consequences most important to that client’s life.

If your case goes to trial and you are found not guilty, or if your charge is dismissed, you may be eligible for DWI expungement or record sealing — removing all records of the arrest and charge as if they never happened. This is the most complete protection of your future available under Texas law, and it is only possible when the case ends in the right way. Every decision made from arrest through resolution affects whether expungement is available. That is yet another reason the decision to fight — rather than plead — should be made with experienced legal counsel, not in a moment of panic.

The 15-Day Clock Is Already Running

If you were arrested for DWI in San Antonio, the most urgent deadline in your case is not your court date. It is the 15-day window to request your ALR hearing with the Texas DPS. That deadline has been running since the night of your arrest.

After that, the most important decision is who represents you. A first offense DWI is not a minor traffic ticket. The combined weight of the statutory penalties, the surcharges, the insurance consequences, the professional implications, and the permanent criminal record make it one of the most consequential legal events in the life of an ordinary person who has never been in trouble before.
