A first DWI arrest in Texas feels overwhelming, but it's also the charge level with the most room to maneuver. Many first-offense cases in Dallas-Fort Worth resolve without any additional jail time — and some are dismissed or reduced entirely when an attorney finds weaknesses in the stop, the tests, or the paperwork.
What a first DWI actually carries
A first-offense DWI is a Class B misdemeanor under Texas Penal Code § 49.04:
| Penalty | Range |
|---|---|
| Jail time | 72 hours to 180 days (6-day minimum if an open container was in the vehicle) |
| Court fine | Up to $2,000 |
| State fine (§ 709.001) | $3,000 — assessed on top of the court fine |
| License suspension | 90 days to 1 year |
| Other | DWI education program, possible ignition interlock, possible probation with conditions |
If your BAC was 0.15 or higher, a first offense jumps to a Class A misdemeanor: up to one year in jail, a $4,000 court fine, and a $6,000 state fine.
The two cases you're actually fighting
Most people don't realize a DWI arrest creates two separate proceedings:
- The criminal case — determines guilt, jail, fines, and probation.
- The ALR case — a civil process that suspends your license unless you request a hearing within 15 days.
Winning one doesn't automatically win the other, which is why fast legal help matters even for a first offense.
How first-offense cases are defended
- The traffic stop. No reasonable suspicion, no lawful stop — and everything after it can be suppressed.
- Field sobriety tests. The three standardized tests are frequently administered incorrectly, on bad surfaces, or to people with medical conditions that mimic impairment.
- Breath test reliability. Texas breath machines require strict maintenance and operator certification — records often tell a different story than the printout.
- Rising BAC. Alcohol absorbs over time; your BAC at the station may overstate your BAC behind the wheel.
Probation, reductions, and record sealing
For genuine first offenses with no accident or aggravating factors, probation (community supervision) is a common outcome — typically with a DWI education class, community service, and fees. Some cases are reduced to a non-DWI charge like obstruction of a roadway. And while Texas does not allow DWI convictions to be expunged, certain first-time Class B convictions may qualify for an order of nondisclosure (record sealing) after a waiting period.
