Dallas DWI Charges: Offenses & Penalties

A DWI charge in Dallas can affect more than your freedom. Depending on the facts, it can cost you your driver’s license, your employment, your professional licenses, and your right to possess a firearm. The charge level and the long-term consequences are shaped by what happened at the stop, what you did afterward, and how the case is handled from the start.

Texas DWI law is not one size fits all. A first arrest looks very different from a third, and a crash that causes injury changes the entire charge picture. A Dallas DWI attorney can walk you through what you are actually facing: the charge levels, what prosecutors must prove, how penalties escalate, and what happens to your license while the case is pending.

Texas defines “intoxicated” two ways under the Texas Penal Code Chapter 49 DWI statutes. The first is a blood alcohol concentration (BAC) of 0.08 or higher. The second is the loss of normal use of mental or physical faculties because of alcohol, a drug, a controlled substance, or any combination. Both paths can support a DWI charge. A prosecutor does not need a chemical test result to build a case, and a test result alone does not settle the matter.

One common source of confusion is the difference between DWI and DUI in Texas. DWI, or Driving While Intoxicated, applies to drivers of any age under Tex. Penal Code Chapter 49. DUI, or Driving Under the Influence, applies only to drivers under 21 with any detectable amount of alcohol, even below 0.08. The two offenses carry different charge levels, different penalties, and different long-term consequences. If the driver is under 21, the zero-tolerance rules work differently.

Not all DWI charges in Dallas carry the same weight. The offense level rises with prior convictions, aggravating facts, and specific circumstances attached to the charge. Understanding where a charge falls on that ladder is the first step toward understanding what you are actually facing.

A first-offense case involves more than the punishment range. The stop, the field sobriety testing, the chemical test, and the officer’s paperwork all deserve a close review.

A second DWI is a Class A misdemeanor under Tex. Penal Code § 49.09, carrying a mandatory minimum of 30 days in county jail, a maximum of one year, and a fine of up to $4,000. License suspension runs from 180 days to two years.

A third DWI is a third-degree felony. The range is 2 to 10 years in prison and a fine of up to $10,000. That shift from misdemeanor to felony affects firearm rights, professional licensing, employment in certain fields, and immigration status for non-citizens. The road to any form of record relief becomes significantly harder after a felony DWI.

Bond conditions in a felony DWI case in Dallas County tend to be more restrictive as well. Courts may require ignition interlock installation as a condition of pretrial release, not just after sentencing.

Prior convictions are the most common enhancement driver in DWI cases, but they are not the only one. Each prior changes what you are facing and how the prosecution approaches the case.

The penalty ranges below are set by Texas statute. Courts have discretion within those ranges, and actual outcomes depend on the specific facts and how the case moves through Dallas County. These ranges reflect the law as written, not typical or guaranteed results.

These ranges cover the criminal case only. They do not include administrative license consequences, the DPS surcharge program, or the real financial cost of a conviction.

An enhanced DWI carries more serious consequences because of a specific aggravating fact. In Texas, certain circumstances automatically push a standard DWI into a higher charge category, regardless of prior history. These provisions are built into the statute, not left to prosecutorial discretion.

If a person is arrested for DWI in Dallas while a passenger under 15 years of age is in the vehicle, the charge becomes a state jail felony under Tex. Penal Code § 49.045. That is true without a prior record and even if no one was injured. The punishment range for a state jail felony is 180 days to two years in a state jail facility, plus a fine of up to $10,000. The child’s presence alone triggers the enhancement.

A DWI arrest in Dallas starts two separate proceedings. The first is the criminal case in Dallas County court. The second is an Administrative License Revocation proceeding managed by the Texas Department of Public Safety under Tex. Transp. Code Chapters 524 and 724. These tracks run on different timelines and require separate action.

Failing a breath or blood test triggers a 90-day suspension. Refusing testing raises that to 180 days and can push the arresting officer toward seeking a blood-draw warrant, which creates a separate set of evidentiary issues in the case. License suspension is not automatic if you act in time.

The statutory fine is only part of what a DWI conviction in Dallas will cost.

Court fines run up to $2,000 for a first DWI and up to $4,000 for a second. On top of that, the Texas Department of Public Safety assesses an annual surcharge for three years following a conviction: $1,000 per year for a first offense, $1,500 for a second, and $2,000 per year if the BAC was 0.16 or higher.

An ignition interlock device, required as a condition of bond or probation in many Dallas DWI cases, runs between $70 and $150 per month in rental and calibration fees. Insurance adds another layer: a conviction triggers SR-22 filing requirements, and premiums often double or triple and stay elevated for years.

The total real-world cost of a DWI conviction in Dallas can reach $10,000 to $17,000 over three years, before accounting for lost wages or long-term career consequences.

How you handle the stop shapes the case. A few clear points:

A DWI conviction generally cannot be expunged in Texas. Cases resolved without a conviction, including dismissals and acquittals, may qualify for record relief under Tex. Code Crim. Proc. Chapter 55A, depending on the outcome and timing. Deferred adjudication is generally not available for DWI in Texas, which also limits nondisclosure options. Eligibility depends entirely on how the case was resolved.

Yes. Commercial driver’s license holders face a BAC threshold of 0.04 while operating a commercial vehicle, not 0.08. A first DWI conviction can result in a one-year CDL disqualification. A second can result in lifetime disqualification. For professional drivers, the career consequences often exceed the criminal penalty itself.

Probation is a common outcome in Dallas DWI cases. Standard conditions typically include:

A probation violation can result in revocation and imposition of the original jail or prison sentence.
