First DWI in Texas: Penalties and How to Protect Your Record

What a first DWI in Texas can cost

A first DWI is charged under Tex. Penal Code §49.04 as a Class B misdemeanor. On conviction, the range is 72 hours to 180 days of confinement, a fine up to $2,000, and a license suspension of 90 days to one year. An open container in the car raises the minimum confinement to six days.

There is a second bill many people never see coming. A DWI conviction also triggers a state fine under Tex. Transp. Code §709.001: $3,000 for a first conviction, or $6,000 if the result was 0.15 or higher. A judge can waive it for someone who cannot pay, but it is on the books, on top of court costs and probation fees.

The ranges on paper rarely match the outcomes for first offenders. Most first DWI cases in Dallas County resolve without jail time. But the ranges set the negotiating field, which is why the charge level matters so much. For how a case moves from arrest to resolution, start with our complete Texas DWI defense guide.

When a first DWI becomes a Class A

Under Tex. Penal Code §49.04(d), a result of 0.15 or more bumps a first DWI to a Class A misdemeanor. The statute pins the number to the time the analysis was performed, not the time you were driving. That wording matters. A sample taken an hour after the stop can read higher than your level behind the wheel, because alcohol keeps absorbing after you stop drinking.

The 0.15 finding doubles the jail and fine exposure, doubles the state fine, and closes the door on the standard sealing path. A borderline 0.15 result is worth fighting for both reasons: it protects the sentence and it protects the record.

Probation vs. deferred adjudication

Most first DWI cases end in one of two supervised outcomes, and the difference between them is the difference between a permanent record and a sealable one.

Probation (community supervision) follows a conviction. You stay out of jail by completing conditions: classes, community service, fees, no alcohol, and sometimes an interlock. But the conviction underneath it is permanent. It cannot be expunged, ever.

Deferred adjudication works differently. You enter a plea, the judge defers a finding of guilt, and if you complete the supervision the case is dismissed without a conviction. A 2019 change in Texas law opened deferred adjudication to most first-time, non-aggravated DWI charges. It is not available when the result was 0.15 or higher or when the driver holds a commercial license, and it still counts as a prior if there is ever a second DWI. For record protection, though, deferred is usually the stronger endgame.

Interlock conditions

An ignition interlock can show up at three points: as a bond condition while the case is pending, as a condition of deferred adjudication or probation, and as a voluntary restriction after the case. On deferred for DWI, judges order an interlock in most cases. The device carries a monthly cost and goes on any car you drive. The upside is real: an interlock restriction held for at least six months cuts the later sealing wait from five years to two.

Sealing your record: nondisclosure basics

Texas never expunges a DWI conviction. What it offers instead is an order of nondisclosure under Tex. Gov't Code §411.0731, which seals the case from public background checks. Employers and landlords stop seeing it. Law enforcement and licensing agencies still can.

The eligibility basics for a first DWI conviction:

1. It was your first and only offense. No other convictions or deferred outcomes, apart from minor traffic fines.
2. The result was under 0.15. A Class A finding under §49.04(d) takes this path off the table.
3. No accident involving another person.
4. You completed the sentence, including fees and any suspension.
5. You waited out the period: two years if you held an interlock restriction for at least six months, five years if you did not.

Here is the part most people learn too late: eligibility is decided by how the case resolves, years before you ever file the petition. A plea structured without sealing in mind can lock the record open for good.

Insurance and employment fallout

The courtroom penalties are only part of the cost. After a DWI conviction, Texas requires an SR-22 insurance certificate, typically for three years, and insurers reprice you as high risk. Premiums climb and stay up.

On the work side, a DWI shows on background checks for jobs, apartments, and professional licenses. Nurses, teachers, pilots, and commercial drivers face their own licensing boards on top of the criminal case. A conviction can end rideshare and delivery driving, and for non-citizens it can complicate status and naturalization in some circumstances. None of this fallout waits for sentencing. Some of it starts at arrest, which is another reason the goal from day one is keeping a conviction off the record.

Why pleading fast is usually a mistake

At the first court setting, a quick guilty plea can feel like the fast way back to normal life. It is usually the most expensive choice in the room, for five reasons:

1. A conviction is permanent. There is no undo, and no expunction later.
2. The first offer is rarely the best offer. Prosecutors price cases before anyone has pushed back on the evidence.
3. Nobody has watched the video yet. The stop and the field tests have not been reviewed by anyone on your side.
4. A fast plea can forfeit deferred adjudication and sealing. The structure of the plea decides your record for life.
5. It does not fix your license. The ALR suspension is a separate civil case with its own 15-day deadline.

Some first DWI cases end in reduction or dismissal when the stop or the testing does not hold up. Every case is different. Past results do not guarantee future outcomes. The point is simpler: you cannot know what your case is worth until someone has examined it. If you refused the breath test, the State's evidence may be thinner than you think. See what happens when you refuse a breathalyzer in Texas.

What a defense review looks for

Before any plea decision, a defense review works through three layers of the case:

• The stop. Was there reasonable suspicion, and does the video actually show the violation the officer wrote down?
• The test. Field tests run to standard? Breath machine maintained and the observation period honored? Blood drawn, stored, and tested with a clean chain of custody?
• The procedure. Statutory warnings read correctly, the ALR deadline handled, and every page of discovery actually produced.

Weakness in any layer changes the negotiation, and sometimes ends the case. That review is the starting point of our DWI defense practice, and the deeper strategy walkthrough lives in the Texas DWI defense guide.
