What Is a First-Time DWI Lawyer in Houston For?
A first-time DWI in Houston is defined under Texas Penal Code § 49.04 as operating a motor vehicle in a public place while intoxicated. Intoxication has two independent legal definitions. The first: a blood alcohol concentration (BAC) of 0.08% or higher. The second: loss of normal use of mental or physical faculties due to alcohol, drugs, or a controlled substance — regardless of BAC level. A first time DWI lawyer Houston drivers hire after an arrest checks which definition the state is relying on before the case moves further.
A first-time DWI with no aggravating factors is classified as a Class B misdemeanor in Texas. If your BAC was 0.15 or higher, the charge is elevated to a Class A misdemeanor — still a misdemeanor, but with higher penalties. A first time DWI lawyer Houston clients trust reviews the BAC reading closely, since it determines which penalty range applies.
What Does a First-Time DWI Lawyer Houston Clients Hire Handle First?
A first-time DWI in Houston, without aggravating factors, is a Class B misdemeanor under Texas law: 72 hours to 180 days in county jail, up to $2,000 in fines, and 90 days to 1 year of license suspension. A BAC of 0.15 or higher elevates the charge to a Class A misdemeanor with up to 1 year in jail and a $4,000 fine. DPS annual surcharges of $1,000–$2,000 per year for three years apply on top of court fines.
| Penalty | Standard (BAC under 0.15) | Enhanced (BAC 0.15+) |
|---|---|---|
| Classification | Class B Misdemeanor | Class A Misdemeanor |
| Jail | 3–180 days | Up to 1 year |
| Fine | Up to $2,000 | Up to $4,000 |
| License Suspension | 90 days – 1 year | 90 days – 1 year |
| DPS Annual Surcharge | $1,000–$2,000/yr for 3 years | $1,000–$2,000/yr for 3 years |
| Ignition Interlock | Possible (judge discretion) | Required for BAC ≥ 0.15 |
| Criminal Record | Permanent if convicted | Permanent if convicted |
Beyond the court-ordered penalties, a first-time DWI conviction can affect your employment, professional licenses, immigration status, auto insurance rates, and security clearances. The long-term consequences often exceed the immediate court penalties. Because these collateral consequences can outlast the criminal case itself, a first time DWI lawyer Houston professionals recommend hiring quickly maps out every angle of exposure before you enter a plea.
What Happens After a First-Time DWI Arrest in Houston?
A first-time DWI arrest in Houston immediately triggers two parallel legal processes: the criminal case in Harris County court and the Administrative License Revocation (ALR) proceeding with the Texas DPS. Both begin at the moment of arrest. The 15-day ALR deadline is the most time-critical action — missing it causes automatic license suspension before your criminal case is resolved.
Arrest & Processing
You are arrested, booked, and typically released on bond within hours. You receive paperwork — including a temporary driving permit valid for 40 days if you provided a breath/blood sample (or 25 days if you refused). Read everything carefully.
The 15-Day Deadline (ALR Hearing Request)
A first-time DWI lawyer Houston clients call immediately knows: within 15 calendar days of your arrest, you must request an Administrative License Revocation (ALR) hearing with the Texas DPS to contest your license suspension. This is separate from your criminal case. Missing this deadline = automatic suspension. A first time DWI lawyer Houston families call within days of an arrest treats this deadline as the top priority. Learn about the 15-Day Rule →
Criminal Arraignment
You appear before a judge who formally reads the charges and sets bail (if not already done). You enter a plea — almost always "not guilty" at this stage. A first-time DWI lawyer in Houston begins gathering all evidence at this stage: police reports, dashcam video, breathalyzer records, officer training records.
Pre-Trial Motions & Negotiations
Your attorney files pre-trial motions to suppress illegally obtained evidence, challenge test results, or dismiss the case entirely. Many DWI cases are resolved favorably at this stage through negotiation or successful suppression motions. A first time DWI lawyer Houston clients depend on for this stage knows exactly which motions carry the most leverage.
Trial or Resolution
If the case proceeds to trial, a jury of your peers decides guilt or innocence. As a first-time DWI lawyer in Houston with an extensive trial record, Herman Martinez cross-examines police officers and forensic experts with precision. Many cases resolve before this point.
How Does a First-Time DWI Lawyer Houston Trusts Build Your Defense?
Herman defends first-time DWI charges by attacking the traffic stop, the field sobriety test administration, and the chemical test results — each a separate point where the state's case can collapse. The state must prove every element beyond a reasonable doubt. Herman, as a former Chief Prosecutor and NHTSA-certified attorney, identifies which element is weakest in each specific case.
Was the Traffic Stop Legal?
Police must have reasonable suspicion to pull you over. If the stop was illegal — for example, an officer pulling you over based on a hunch with no observed traffic violation — everything that follows can be suppressed. No traffic stop, no case. As a first-time DWI lawyer in Houston, Herman scrutinizes every detail of the initial stop.
Were Breath or Blood Tests Accurate?
Breathalyzer machines require strict calibration and maintenance. Operators must be certified and follow exact protocols. Blood tests must have an unbroken chain of custody. As a Houston first-time DWI lawyer with NHTSA certification in field sobriety testing, Herman's deep knowledge of forensic testing gives him an edge in attacking chemical evidence.

Were Field Sobriety Tests Properly Administered?
The Standardized Field Sobriety Tests (HGN, Walk and Turn, One Leg Stand) have strict administration protocols set by NHTSA. Even slight deviations can invalidate the results. As an NHTSA-certified practitioner himself, Herman knows exactly what to look for. Learn about field sobriety tests →
Were There Medical or Environmental Explanations?
Certain medical conditions (diabetes, GERD, neurological disorders) can produce false breathalyzer readings or impair coordination in ways that mimic intoxication. Environmental factors (mouthwash, paint fumes, certain foods) can also affect test results. A first-time DWI lawyer Houston clients hire should raise these explanations early, since they can create reasonable doubt. A first time DWI lawyer Houston juries find credible presents this scientific context clearly and early.
Were Your Rights Violated?
Police must advise you of your Miranda rights at the appropriate time. Any statements made after an illegal detention or before Miranda warnings were given may be suppressible. A thorough first-time DWI lawyer Houston clients trust reviews every police body cam, dashcam, and written report for rights violations.
Herman Martinez didn't just study the DWI prosecution handbook — he wrote cases using it. As a former Harris County Chief Prosecutor, he knows which evidence district attorneys rely on most heavily, what makes a breathalyzer result hard to challenge in court, and where the cracks in a typical DWI prosecution exist. That knowledge now works for you — it's exactly what a first time DWI lawyer Houston clients choose brings to the negotiating table. Why hire a former prosecutor →
After a first-time arrest, the 15-day ALR deadline is the most immediate concern — see the 15-day rule page for how to protect your license before anything else. If you're evaluating whether to fight the charge or pursue diversion, see the DWI divert program page for how the Harris County diversion program works and who qualifies. Either way, a first time DWI lawyer Houston residents rely on maps out the fastest path to resolution during the first phone call.
Frequently Asked Questions — First-Time DWI Lawyer Houston
No — a standard first-time DWI is a Class B misdemeanor. It can become a felony if a child under 15 was in the vehicle (state jail felony), you caused serious injury (intoxication assault, 3rd-degree felony), or someone was killed (intoxication manslaughter, 2nd-degree felony). A BAC of 0.15+ elevates to Class A misdemeanor. A first time DWI lawyer Houston families search for after an arrest can clarify which category applies within minutes.
The law requires a minimum of 3 days in jail upon conviction, but many first-time offenders receive probation without serving additional jail time. A strong defense can sometimes avoid a conviction entirely — through dismissals, suppression of evidence, or participation in the Harris County DWI Divert Program. Note: standard deferred adjudication is not available for DWI charges in Texas. A first time DWI lawyer Houston clients hire routinely pursues probation instead of jail time for qualifying cases.
Yes — and it happens more than most people expect. First-time cases are dismissed when the stop was unlawful, breath or blood tests had procedural violations, field sobriety tests were administered incorrectly, or there is insufficient evidence. Herman has achieved dismissals including cases with positive chemical test results. This is the track record a first time DWI lawyer Houston clients search for before hiring. See case results →
A DWI conviction is permanent — it cannot be expunged or sealed. However, if your case is dismissed or you are found not guilty, you may qualify for an expunction that removes the arrest entirely. This is one of the most compelling reasons to fight aggressively rather than accept a plea. DWI expunctions →
An automatic suspension is triggered but can be contested. You have 15 days to request an ALR hearing — if you do, the suspension is delayed while your case is pending. Winning prevents it entirely. Even if suspended, an occupational driver's license lets you drive to work, school, and medical appointments. A first time DWI lawyer Houston drivers call can request this permit on your behalf.

Harris County's DWI Divert Program offers qualifying first-time offenders a chance to complete education and supervision requirements in exchange for dismissal. Not everyone qualifies — it depends on BAC level, the specific facts of the case, and no prior criminal history. Herman evaluates eligibility for every eligible client on the first call. DWI Divert Program →
Yes. For first-time DWI convictions in Texas, probation (community supervision) is commonly available as an alternative to jail. Probation conditions typically include DWI education classes, community service, alcohol evaluation, monthly reporting, and sometimes an ignition interlock device. Herman advocates for the most favorable probation terms when a plea is unavoidable.
A DWI conviction shows up on background checks and can affect current and future employment, especially for jobs requiring a security clearance, professional license, CDL, or work with vulnerable populations. The arrest itself (even without conviction) may appear on background checks unless expunged. Fighting the charge is always the best career protection strategy.
Yes — DWI can have serious immigration consequences. A DWI conviction may be classified as a crime of moral turpitude or an aggravated felony depending on the circumstances, potentially affecting green card applications, naturalization, and visa renewals. Non-citizens should treat a DWI charge with extreme urgency and ensure their criminal attorney understands the immigration stakes.
Texas DPS imposes annual surcharges on top of court fines. After a first DWI conviction, you pay $1,000 per year for 3 years (or $2,000/year if BAC was 0.16+) just to keep your driver's license. These surcharges are separate from court fines and must be paid to maintain your driving privileges. DWI surcharge guide →
