First Offense DWI in Texas: What You're Actually Facing
A first DWI in Texas is a Class B misdemeanor — but the real cost is far greater than the $2,000 fine. Surcharges, insurance increases, and a permanent criminal record can cost you tens of thousands of dollars over time. Here is exactly what the law says and what a skilled defense can do about it.
Is Jail Mandatory for a First DWI in Texas?
Yes — but in limited form. Under Tex. Transp. Code §49.04(b), a first offense DWI carries a mandatory minimum of 72 hours (3 days) in county jail. This is the floor, not the typical outcome. Most first-offense DWI cases do not result in additional jail time beyond what was served at the time of arrest.
If your blood alcohol concentration (BAC) was 0.15 or higher at the time of arrest, your charge is elevated to a Class A misdemeanor under Tex. Transp. Code §49.04(d). The mandatory minimum remains 72 hours, but the maximum penalty increases to one year in jail and a $4,000 fine.
Alternatives to jail — such as community supervision (probation), home confinement, or an ignition interlock device — are frequently available on first-offense DWI cases in Texas. An experienced DWI attorney negotiates for these alternatives from the first appearance.
- Tex. Transp. Code §49.04(b) — First DWI — Class B misdemeanor, 72-hour mandatory minimum, up to 180 days
- Tex. Transp. Code §49.04(d) — BAC ≥0.15 — Class A misdemeanor, up to 1 year and $4,000 fine
How Long is Probation for a First DWI in Texas?
Community supervision (what most people call probation) for a first-offense DWI in Texas runs up to 2 years. This is authorized under Tex. Code Crim. Proc. Art. 42A.052 for misdemeanor DWI cases.
During community supervision, you are typically required to:
• Report to a probation officer monthly
• Complete 24 hours of community service
• Attend a DWI education program (DPS-approved)
• Attend a victim impact panel
• Install an ignition interlock device on any vehicle you drive
• Pay monthly supervision fees ($25–$60/month)
• Submit to random alcohol and drug testing
• Pay all fines, court costs, and surcharges
Violating any probation condition can result in revocation and imposition of the original jail sentence. A defense attorney who negotiates your probation terms carefully can make those two years significantly more manageable.
- Tex. Code Crim. Proc. Art. 42A.052 — Community supervision — misdemeanor DWI, maximum 2 years
- Tex. Transp. Code §521.246 — Ignition interlock device required during license suspension
What Are the Full Penalties for a First Offense DWI in Texas?
The statutory penalties for a first DWI conviction under Tex. Transp. Code §49.04 include:
• Criminal fine: Up to $2,000 (Class B) or $4,000 (Class A if BAC ≥0.15)
• Jail: 3 to 180 days (up to 1 year if Class A)
• Driver's license suspension: 90 days to 1 year (Tex. Transp. Code §524.022)
• DPS annual surcharge: $1,000–$2,000 per year for 3 years under the Driver Responsibility Program
• Court costs: Typically $1,000–$2,500
The true financial impact often exceeds $10,000 when you add insurance premium increases (typically 60–80% higher for 3–5 years), ignition interlock installation ($70–$150) and monthly monitoring ($60–$90), SR-22 insurance, and time off work for court appearances and probation meetings.
A DWI that is dismissed or results in acquittal has none of these consequences. A plea to a lesser charge (such as obstruction of a passageway) avoids the DWI conviction entirely. These outcomes are not guaranteed, but they are achieved regularly by experienced Texas DWI defense attorneys.
- Tex. Transp. Code §49.04 — First DWI offense — offense classification and penalty range
- Tex. Transp. Code §524.022 — License suspension period after DWI arrest — 90 days to 1 year
- Tex. Transp. Code §708.102 — Driver Responsibility Program — annual surcharges on DWI convictions
Can a First DWI Be Dismissed or Reduced in Texas?
Yes. Many first-offense DWI cases in Texas are dismissed or reduced — especially when the defense challenges the stop, the field sobriety tests, or the breathalyzer or blood test results.
Common defense strategies for first-offense DWI cases include:
• Challenging the lawfulness of the traffic stop (Fourth Amendment)
• Attacking field sobriety test validity (lighting, surface, medical conditions)
• Challenging breathalyzer calibration records and operator certification
• Contesting blood draw chain of custody and laboratory procedures
• Arguing rising BAC (BAC was below 0.08 at time of driving, but rose by time of test)
• Reviewing dashboard and body camera footage for inconsistencies with the officer's report
Not every case has a winner — but every case deserves a thorough defense review before any plea is entered. Texas Defense Team evaluates the full evidence package before advising a client on how to proceed.
What Is the 15-Day ALR Deadline After a DWI Arrest?
Within 15 days of a DWI arrest in Texas, you or your attorney must request an Administrative License Revocation (ALR) hearing with the Texas DPS under Tex. Transp. Code §524.031. This is separate from your criminal DWI case.
Missing the 15-day deadline results in automatic license suspension:
• 90 days for first offense if you submitted to a test
• 180 days for first offense if you refused the breath or blood test (Tex. Transp. Code §724.035)
The ALR hearing is also an invaluable tool for your criminal defense. Your attorney can cross-examine the arresting officer under oath, subpoena the breath test records, and preserve testimony that will be used later in your criminal case. This discovery opportunity is completely lost if you miss the 15-day deadline.
- Tex. Transp. Code §524.031 — 15-day deadline to request ALR hearing after DWI arrest
- Tex. Transp. Code §724.035 — Refusal suspension — 180 days first offense
Frequently Asked Questions
Is a first DWI in Texas a felony?+
No. A first offense DWI in Texas is a Class B misdemeanor under Tex. Transp. Code §49.04 — unless you had a child passenger under 15 in the vehicle, in which case it becomes a state jail felony regardless of prior record.
Can I get deferred adjudication for a first DWI in Texas?+
No. Texas explicitly prohibits deferred adjudication for DWI under Tex. Code Crim. Proc. Art. 42A.102(b). This means any plea of guilty or no contest results in a conviction on your record — making acquittal, dismissal, or a reduction to a different charge critically important.
Will a first DWI affect my job?+
Potentially yes. A DWI conviction is a permanent criminal record visible on background checks. Professional licenses (nursing, law, teaching, commercial driving) may be affected. Commercial driver's license holders face especially severe consequences — a CDL can be disqualified for one year on a first DWI conviction.
How much does a first offense DWI cost in Texas total?+
All-in, a first DWI conviction typically costs $10,000–$17,000 over 3 years when you account for fines, court costs, DPS surcharges ($1,000–$2,000/year for 3 years), ignition interlock, insurance increases, probation fees, and mandatory education classes. The cost of a defense attorney is almost always less than the total cost of a conviction.
How long does a first DWI case take in Texas?+
Most first-offense DWI cases in Texas resolve in 6–18 months. Cases that go to trial take longer. County-to-county timelines vary significantly — Williamson County cases typically move faster than Travis County cases.
