DWI Laws in Houston, TX:
If you or someone close to you was just arrested for DWI in Houston or anywhere in Harris County, take a breath. Here’s what to do next in Harris County — and what actually matters first. Below is a straight‑talk walkthrough of what happens next: how the ALR license suspension works, what to expect at the Harris County Criminal Justice Center (1201 Franklin St.), and where a lawyer can actually help protect your license and your case.
About this guide: Harris County–specific and based on current Texas law and local procedures. Time‑sensitive steps—especially the ALR hearing request window—are highlighted so you don’t miss a deadline.
Step 1: The Stop — How Officers Build a DWI Case
Most DWI stops in Harris County start with something routine—rolling a stop, drifting over a lane marker, a broken taillight, or a minor crash. Once you’re stopped, officers look for signs of impairment. Common next steps:
- Ask where you were coming from and whether you’ve been drinking
- Administer standardized field sobriety tests (walk‑and‑turn, one‑leg‑stand, HGN)
- Request a breath or blood sample
The stop is in the rear‑view now. From here, ask yourself: Was the stop lawful? Were the tests administered and recorded correctly? A local DWI defense attorney can audit body‑cam/dash‑cam and testing logs to find errors that can lead to suppression of evidence.

Step 2: Arrest & Booking at the JPC (What Actually Happens)
If the officer thinks there’s probable cause, you’ll be arrested under Texas Penal Code § 49.04 and taken for booking. In Harris County, most people go through the Sheriff’s Joint Processing Center (JPC) on N. San Jacinto; some are routed through other Sheriff facilities such as Baker Street. You’ll be searched, photographed, fingerprinted, and either held for a magistrate or released after bond is set.
During booking, officers may request an evidentiary breath or blood sample. Refusing or failing a chemical test triggers the civil license process described next.

Step 3: Your License (ALR) — The Deadline Most People Miss
After a DWI arrest, DPS opens a separate civil case called Administrative License Revocation (ALR)—it runs alongside the criminal case. For drivers 21+, here’s the short version:
- You have 15 days from service of notice to request an ALR hearing.
- If no hearing is requested, the suspension generally takes effect on the 40th day after notice.
- First‑time refusal of a breath or blood test: 180‑day suspension.
- First‑time failure (BAC ≥ 0.08): 90‑day suspension.
If you consented to a blood draw, DPS usually mails a Notice of Suspension after the lab results. You then have 20 days from the mailing date to request the hearing. Mark that date—DPS mail starts real deadlines. Bottom line: don’t miss the ALR deadline.

Step 4: Bond & Conditions — What You’ll Be Required to Do
In practice, most first‑time Harris County DWI defendants qualify for release on bond—sometimes on a personal bond. Expect conditions and read them carefully. The magistrate/judge sets bond and any conditions, which can include:
- No alcohol use and random testing
- Ignition interlock device
- No new arrests; keep court contact information updated

Step 5: Arraignment at 1201 Franklin — Your First Court Setting
Your first appearance—arraignment—is typically scheduled within a few weeks. Harris County misdemeanor DWI cases are heard in the Harris County Criminal Courts at Law at the Criminal Justice Center (1201 Franklin St., Houston, TX 77002).
Arraignment (your first appearance): what happens:
- The court confirms your identity and that you understand the charge
- You enter a plea (often Not Guilty while your lawyer investigates)
- The court addresses bond conditions and sets/reset dates
Missing court can lead to a warrant. If you’ve already received a date, add it to your calendar and speak to counsel about any conflicts well in advance. Plan for security screening and busy elevators downtown; arrive early.
Step 6: Evidence, Motions & Negotiation — Where Cases Are Won
After arraignment, your lawyer requests discovery and reviews evidence such as:
- Body‑cam & dash‑cam video
- Breath‑test records (calibration, maintenance, operator certification)
- Blood‑test chain‑of‑custody and lab documentation
- The initial traffic‑stop basis and detention timeline
In Houston courts, defense lawyers often scrutinize whether the stop was lawful, how SFSTs were run, the breath‑testing protocol, and blood‑draw chain‑of‑custody. Strong issues can lead to dismissals, charge reductions, or suppression that changes the plea/trial posture.

Step 7: Potential Penalties Under Texas Law
Under Texas Penal Code § 49.04, a first DWI is generally a Class B misdemeanor with a minimum 72‑hour jail term. Certain facts can enhance the charge and increase the exposure. For a first offense, Texas law allows the following range:
- Jail: 3 to 180 days (often probated if eligible)
- Fine: Up to $2,000 (court costs and fees are separate)
- License: Potential suspension (separate from ALR)
- Education: DWI class; possible alcohol/drug evaluation
- Interlock: Often required with certain bond or probation terms
If the BAC was 0.15 or higher, the charge can be enhanced to a Class A misdemeanor, which increases potential penalties. If an open container was present, the minimum confinement increases. Repeat offenses and injury cases carry far harsher consequences.

Step 8: Real‑World Fallout — Life After a DWI
Even if jail time isn’t part of the outcome, a DWI can reshape day‑to‑day life:
- Job applications and professional licensing
- Auto insurance premiums and SR‑22 requirements
- International travel (e.g., Canada may restrict entry)
- Housing and background checks

Step 9: Do This Now
In the first few days after arrest, keep two priorities front and center:
- Request the ALR hearing before the deadline to fight the automatic suspension.
- Get a Houston DWI attorney involved early to protect evidence, contest the stop/testing, and manage court dates.
