Summary
Texas grades DWI charges by offense level, from a Class B misdemeanor on a first arrest to a felony for repeat convictions, a child passenger, or a case involving serious injury. Tarrant County prosecutes these cases under the same statewide statute, but the specific facts that push a charge higher are what actually decide how serious a case is.
Texas DWI law is written at the state level under Tex. Penal Code Chapter 49 , and it applies the same way in Tarrant County as it does anywhere else in the state. What changes from county to county is not the statute itself, but how the Tarrant County Criminal District Attorney’s office charges and negotiates cases under it, and what the real exposure looks like once prior history and aggravating facts are added.
A DWI charge in Fort Worth starts with one question: does the evidence support the legal definition of intoxication under Section 49.04? Everything else, including the offense level, the punishment range, and whether the case can resolve short of trial, builds outward from that single determination. Any competent Fort Worth DWI attorney begins the same way, working backward from that determination to map out exactly what a client is actually facing.
Key Definitions
Key Legal Definitions: DWI, DUI & Implied Consent
What Does Intoxication Mean Under Texas Law?
Texas defines intoxication two ways under Section 49.04. The first is a measured blood or breath alcohol concentration of 0.08 or higher. The second is the loss of normal use of mental or physical faculties, whether from alcohol, a drug, or a combination of substances. A prosecutor does not need a specific test result to bring a charge under the second definition, which is why an arrest can happen even when a later test comes back under 0.08.
DWI Vs. DUI: The Legal Difference
DWI applies to any driver who meets the legal definition above. DUI is a separate, narrower offense that applies only to drivers under 21, who can be charged under Texas zero-tolerance law for any detectable amount of alcohol, regardless of whether they meet the 0.08 threshold.
What Is Implied Consent In Texas?
By driving on a Texas public road, every driver has already agreed, by law, to submit to a breath or blood test if lawfully arrested for DWI. That is the implied consent doctrine under Tex. Transp. Code § 724.011. Refusing the test does not withdraw that consent after the fact. It only changes the immediate consequence, since refusal carries its own separate license suspension.
OFFENSE CLASSIFICATION
Misdemeanor Vs. Felony DWI Charges In Texas
Not every DWI is treated the same under Texas law. The offense level depends on prior convictions and on a small number of specific aggravating facts.
| FACTOR | MISDEMEANOR DWI | FELONY DWI |
|---|---|---|
| Prior Convictions | None or one prior | Two or more priors (3rd DWI becomes a 3rd-degree felony) |
| Child Passenger | Not applicable | Under 15 in the vehicle elevates to a state jail felony |
| Injury Or Death | Not applicable | Serious injury (intoxication assault) or death (intoxication manslaughter) |
| Typical Range | Fine and county jail time | State prison time and longer license consequences |
Which category a case actually falls into is rarely obvious at the outset. It often comes down to exactly what DWI defense strategies and evidence in Texas can be raised against the specific facts the State is relying on.
PENALTIES BY OFFENSE LEVEL
Tarrant County DWI Penalties By Offense Level
| Offense | Classification | Jail / Prison | Maximum Fine | License Suspension |
|---|---|---|---|---|
| 1st DWI | Class B Misdemeanor | 72 hours to 180 days | $2,000 | 90 days to 1 year |
| 1st DWI, BAC 0.15 Or Higher | Class A Misdemeanor | Up to 1 year | $4,000 | 90 days to 1 year |
| 2nd DWI | Class A Misdemeanor | 30 days to 1 year | $4,000 | 180 days to 2 years |
| 3rd DWI | 3rd-Degree Felony | 2 to 10 years | $10,000 | Up to 2 years |
| DWI With Child Passenger | State Jail Felony | 180 days to 2 years | $10,000 | 180 days to 2 years |
| Intoxication Assault | 3rd-Degree Felony | 2 to 10 years | $10,000 | Up to 2 years |
| Intoxication Manslaughter | 2nd-Degree Felony | 2 to 20 years | $10,000 | Up to 2 years |
In addition to the fines shown above, Texas law imposes a separate state-assessed fee that can range from $3,000 to $6,000 depending on prior convictions and test results.The total financial impact of a first DWI conviction can include additional costs beyond these fines and state-assessed fees.
What Is The Legal BAC Limit In Texas?
The legal limit for a standard driver is 0.08. For a commercial driver operating any vehicle, the limit drops to 0.04 under federal law. For a driver under 21, any detectable amount at all is enough to support a charge under Texas zero-tolerance law.
Are Tarrant County DWI Fines Different From Other Counties?
No. The fine ranges, jail terms, and license suspension periods for DWI are set by the Texas Penal Code and apply the same way in Tarrant County as anywhere else in the state. What differs from county to county is not the law itself, but how individual courts and
prosecutors approach plea negotiations and sentencing within that same statutory range.
AGGRAVATING FACTORS
Aggravating Factors That Increase DWI Penalties
TESTING CONSEQUENCES
Breathalyzer Refusal Vs. Failure: What Changes
| REFUSE THE TEST | FAIL THE TEST | |
|---|---|---|
| License Suspension, 1st Offense | 180 days | 90 days |
| Prosecution Still Possible | Yes, often through a blood warrant | Yes, using the test result directly |
| Evidence Used At Trial | Officer testimony, plus a warrant-based blood result if one was obtained | The breath or blood test result itself |
A refusal does not end the case. It shifts how the State builds it, and the ALR process in Tarrant County treats refusal and a failed test differently in terms of suspension length. Officers in Tarrant County routinely seek a blood draw warrant when a driver refuses, and once that warrant is granted, the result becomes available to the prosecution regardless of the earlier refusal.
COMMERCIAL DRIVERS
DWI Laws For Commercial Driver’s License Holders
Federal law sets a stricter BAC threshold for any driver holding a commercial driver’s license, regardless of what vehicle they were driving at the time of the stop. That threshold is 0.04, half the standard limit. A first conviction results in a one-year disqualification from operating a commercial vehicle. A second results in a lifetime disqualification. For a driver whose livelihood depends on that license, this exposure is often more consequential than the underlying criminal penalty itself.
RECORD RELIEF
Can A DWI Be Expunged In Tarrant County?
Whether a DWI can be expunged depends entirely on how the case resolved, not on how much time has passed. A charge that was dismissed, or that ended in an acquittal, may qualify for expunction under Tex. Code Crim. Proc. Chapter 55A. A conviction does not qualify, regardless of how long ago it occurred.
Deferred adjudication sits in its own separate category, with narrower nondisclosure rules rather than true expunction. Eligibility for deferred adjudication and the nondisclosure process in Tarrant County depend on specific legal requirements and the facts of the case.
