A second DWI in Texas is a Class A misdemeanor under Texas Penal Code §§ 49.04 and 49.09. If convicted, it carries a sentence of 30 days to 1 year in jail and a fine of up to $4,000.
Beyond the primary penalties, a second DWI conviction in Texas imposes additional requirements. These ancillary penalties may include:
- Equip their vehicle with an ignition interlock device (a breathalyzer-like device that prevents a vehicle from starting if the driver's breath alcohol level (BrAC) is over a set limit
- Complete probation (which allows convicted offenders to remain in the community under supervision instead of jail, as long as they follow specific rules)
- Have their driver’s license suspended for up to 2 years.
How Texas Law Defines a Second DWI
Texas treats a DWI as a second offense if you have one prior DWI conviction or qualifying disposition, regardless of how old it is.
- No lookback period applies (Tex. Penal Code § 49.09)
- Out-of-state DWIs can count
- Deferred adjudication may still enhance the charge
- A prior DWI from decades ago can still elevate a new arrest.
Criminal Penalties for a Second DWI in Texas
A second DWI is enhanced under Texas Penal Code § 49.09(a).
Penalties include:
- Charge: Class A misdemeanor (Tex. Penal Code § 49.04)
- Jail: Minimum 30 days, maximum 1 year (Tex. Penal Code § 12.21)
- Fine: Up to $4,000 (Tex. Penal Code § 12.21)
- Probation: Up to 2 years (Tex. Code Crim. Proc. art. 42A)
- Mandatory DWI repeat-offender education
- Ignition interlock device required (Tex. Code Crim. Proc. art. 42A.408)
Unlike a first DWI, jail time cannot be waived if you are convicted.
Administrative License Revocation (ALR) Proceedings: Driver’s License Consequences
A second DWI arrest in Texas automatically begins an Administrative License Revocation (ALR) proceeding, which is the state's civil process for determining whether a person’s driver's license should be suspended following a DWI arrest.
The ALR process is entirely separate from the criminal DWI case and is managed by the Texas Department of Public Safety. Unlike a criminal proceeding, the ALR focuses solely on the circumstances of the arrest, not on guilt or innocence of the criminal charge.
As a result, your license can still be suspended through the ALR process even if the criminal DWI charge is dismissed or you are acquitted. Drivers who fail to request the ALR hearing before the deadline, or who lose their hearing, may still be eligible for an Occupational Driver's License (ODL).
A second DWI automatically triggers a civil license suspension case under Texas’s ALR system.
Governing statutes:
-
Tex. Transp. Code §§ 524.011–524.015
Suspension periods:
- Refusal of test: Up to 2 years (§ 524.035)
- Failure (BAC ≥ 0.08): 180 days to 1 year (§ 524.035)
- ALR hearing deadline: 15 days from arrest (§ 524.032)
License suspension applies even if the criminal case is later dismissed.
Ignition Interlock Requirement
Texas law requires an ignition interlock device (IID) for most second DWI cases.
- Required as a bond condition (Tex. Code Crim. Proc. art. 17.441)
- Required during probation (art. 42A.408)
- Often required for license reinstatement.
Driving without the IID is a separate criminal offense.
How Prosecutors Handle Second DWI Cases
Prosecutors treat second DWIs as repeat-offender cases, not mistakes.
Typical posture:
- Deferred adjudication is usually unavailable (Tex. Code Crim. Proc. art. 42A.102)
- Fewer reduction offers
- Mandatory interlock is demanded early.
- Higher bond conditions
Despite this, the State must still prove intoxication beyond a reasonable doubt.
Can a Second DWI Be Dismissed in Texas?
Yes. In the legal context, a second DWI charge can still be dismissed, meaning the court formally ends or drops the case without a conviction, when:
- The traffic stop violates the Fourth Amendment.
- The DIC-24 statutory warning was misread (Tex. Transp. Code § 724.015)
- Breath or blood testing is unreliable.
- The chain of custody is broken.
- The State cannot prove intoxication at the time of driving.
Prior convictions increase penalties, but they do not lower the burden of proof.
Record Consequences
If convicted, a second DWI:
- A second DWI conviction is permanent and remains on the individual’s criminal record indefinitely.
- Cannot be expunged (Tex. Code Crim. Proc. art. 55.01)
- Cannot be sealed by nondisclosure
- Appears on background checks indefinitely
Only dismissal or acquittal allows full expunction.

Bottom Line
A second DWI in Texas represents a significant legal escalation, governed by Texas Penal Code § 49.09, with mandatory jail exposure and license consequences.
The rationale behind the enhanced penalties is to deter repeat offenses and address concerns about public safety, as individuals with a prior DWI conviction are statistically more likely to reoffend. Consequently, unlike a first DWI, a second offense results in substantially increased penalties, including a minimum 30-day jail sentence that cannot be waived, longer license suspensions, mandatory ignition interlock device requirements, and more stringent probation conditions.
However, the case can still be dismissed if there are failures in the traffic stop, testing, or legal procedure.
Frequently Asked Questions about 2nd DWIs in Texas
