If you were arrested for DWI in Houston last night — or last week — the clock is already running on a deadline most people don’t know exists. Here’s exactly what happens in the first 15 days after a Harris County DWI arrest, what decisions you need to make, and why waiting costs you options.
The Moment of Arrest: What the Officer Did and Why It Matters
When a Harris County or Houston police officer arrests you for DWI, a specific sequence of events begins that has legal consequences at every step. Understanding what happened during the stop — not just the arrest itself — is often the foundation of your defense.
The officer initiated contact with you for a reason. That reason matters under the Fourth Amendment. If the traffic stop lacked probable cause — a broken tail light you didn’t have, a lane change that was technically legal, a tip that didn’t justify the stop — everything that followed may be suppressible. Your attorney’s first job is to examine the stop itself, not just what happened after it.
At the scene, the officer likely asked you to perform Standardized Field Sobriety Tests (SFSTs): the walk-and-turn, the one-leg stand, and the horizontal gaze nystagmus test. These tests are not simply pass/fail measurements of impairment. They are scored observations that require the officer to follow specific administration protocols. Improperly administered tests, results affected by medical conditions (inner ear disorders, knee injuries, neurological issues), poor lighting, or uneven surfaces can all be challenged.
If you submitted to a breath or blood test, the results are part of your case — but they are not unchallengeable. Breathalyzer calibration records, the 15-minute observation period required before testing, and the chain of custody for blood samples are all subject to scrutiny by an experienced DWI attorney.
The Critical 15-Day ALR Deadline — Most People Miss This
This is the most time-sensitive issue in your DWI case and the one most people learn about too late.
When you were arrested for DWI in Texas and either failed or refused a breath or blood test, your driver’s license was automatically confiscated and you received a temporary driving permit valid for 40 days. That 40-day permit will expire — and your license will be automatically suspended — unless you request an Administrative License Revocation (ALR) hearing within 15 days of your arrest.
This is a separate process from your criminal case. The Texas Department of Public Safety (DPS) handles it, not the Harris County courts. Your criminal defense attorney handles both.
The ALR hearing is your opportunity to challenge the license suspension on administrative grounds — not your guilt or innocence in the criminal case, but whether the officer had reasonable suspicion to stop you, whether you were properly informed of consequences, and whether the testing was properly conducted.
Even if you don’t win the ALR hearing, requesting it accomplishes two things: it extends your driving privileges while the hearing is pending, and it gives your attorney an early opportunity to cross-examine the arresting officer under oath — valuable intelligence for the criminal case.
If you don’t request the hearing within 15 days, you lose the right to challenge the suspension entirely. Your license will be suspended automatically 40 days after your arrest, and the only remaining option is to apply for an occupational driver’s license.
Your Harris County DWI Timeline: The First 15 Days
Day 0
Arrest and Booking
You are booked into the Harris County Jail. Your temporary driving permit begins on this date. The 15-day ALR clock starts now.
Day 1–2
Magistration and Bond
A magistrate judge sets your bond — typically $1,000–$5,000 for a first-offense DWI, higher if there was an accident or elevated BAC. Your attorney can appear to argue for lower bond or personal recognizance.
Day 1–5
Hire an Attorney
The sooner you retain a DWI attorney, the more options are preserved. The ALR deadline can be met in 24 hours. Waiting past Day 10 leaves very little margin.
Day 15
ALR Hearing Request Deadline — Hard Stop
Your attorney must request the ALR hearing by this date or your right to a hearing is permanently waived. This is not a flexible deadline.
Day 40
Temporary Permit Expires
If no ALR hearing was requested, your license suspension takes effect today. If a hearing was requested, your driving privileges continue until the hearing is resolved.
What Happens in the Criminal Case
Separate from the license issue, your DWI criminal case will move through the Harris County court system. A first-offense DWI without aggravating factors is a Class B misdemeanor and will be assigned to one of Harris County’s misdemeanor courts.
After magistration, your case proceeds through several stages: arraignment and plea entry, the discovery phase (where your attorney requests all evidence — dashcam, bodycam, breath test records, the officer’s training records), any pre-trial motions including suppression hearings, and ultimately either a negotiated resolution or trial.
What Can a DWI Attorney Actually Do?
A DWI attorney doesn’t just show up to court with you. They examine whether the stop was lawful, whether field sobriety tests were properly administered, whether the breathalyzer was calibrated and the operator was certified, whether your blood was drawn with proper consent and maintained in proper chain of custody, and whether there are any constitutional violations that could suppress evidence or dismiss charges.
They also analyze whether any of the DWI’s classic defenses apply to your specific situation: rising blood alcohol (BAC was below the legal limit while driving but rose to above it by the time you tested), mouth alcohol contamination, medical conditions affecting test results, or a medical necessity defense in rare circumstances.
Consequences Beyond the Criminal Case
A DWI conviction in Texas carries consequences that extend well beyond any jail sentence or fine. A first-offense conviction results in a criminal record that appears in background checks, a license surcharge of up to $2,000 per year for three years (the Driver Responsibility Program), potential consequences on professional licenses, and for non-citizens, possible immigration consequences that must be evaluated carefully before any plea is entered.
If you are not a U.S. citizen: A DWI conviction, while generally not an aggravated felony or crime of moral turpitude under current 5th Circuit law, can still affect discretionary immigration relief and may create complications for naturalization applications, visa renewals, and DACA renewals if charged with intoxication assault or manslaughter. Consult a crimmigration attorney before accepting any plea.
The Single Most Important Thing You Can Do Right Now
It is not complicated: hire a DWI attorney before the 15-day ALR deadline passes. Everything else in your case — the criminal charges, the potential defenses, the negotiation strategy — can be worked on over the coming months. The ALR deadline cannot be extended, cannot be reset, and cannot be appealed once missed.
A DWI arrest in Harris County is not an automatic conviction. Many cases are reduced, dismissed, or won at trial. The outcome depends almost entirely on the quality of the legal representation and how quickly it begins.
