    DWI Defense in Lewisville

    Facing a DWI in Lewisville?

    Deandra Grant Law defends people charged with DWI in Lewisville and along the I-35E corridor, including The Colony, Corinth, Highland Village, Lake Dallas, and Little Elm. We handle every level of the offense, from a first DWI to high-BAC, repeat, and felony charges, including DWI with a child passenger, intoxication assault, and drugged driving. A Lewisville stop is a Denton County case: Lewisville PD, The Colony PD, Corinth PD, DPS, and the sheriff’s office all charge through the Denton County District Attorney, and every one of those cases is heard at the Denton County Courts Building in Denton.

    That is where our Denton office is, directly across McKinney Street from the building that will hear your case. Denton County prosecutes DWI through a dedicated DWI Unit, prosecutors who handle nothing else, so the defense has to know the evidence better than the people who built it. This firm has tried more than 500 cases to verdict and is led by a managing partner who wrote The Texas DWI Manual. In a blood case we request the lab’s underlying data, the chromatograms and calibration records, and read it at the chemistry level.

    Getting started costs nothing. Call or schedule online to talk through what happened. You have just 15 days from the notice of suspension before your license suspension becomes automatic.

    15-Day Deadline

    Arrested in the last 15 days?

    Your license is on its own clock. It starts when you receive the notice of suspension, which in a blood case often arrives by mail weeks later.

    Local Knowledge

    What Actually Happens to a Lewisville DWI

    A Lewisville arrest runs on Denton County's rules. These are the local specifics that shape a defense here.

    Where your case is heard

    Not in Lewisville. Every Denton County DWI is heard at the Denton County Courts Building, 1450 E. McKinney Street in Denton, misdemeanors in the County Criminal Courts at Law and felonies in the District Courts. Our office is directly across the street.

    Who prosecutes

    The Denton County Criminal District Attorney runs a dedicated DWI Unit. Whether the stop was Lewisville PD on I-35E, The Colony PD, or a DPS trooper, the prosecutor across the table works intoxication cases exclusively.

    Jail release

    Lewisville and other Denton County cities may hold you at a city facility first, then transfer you to the Denton County Jail. Bond is set at magistration, usually within 48 hours.

    Where your blood goes

    Denton County blood draws are sent out for testing, and the receiving lab's methods, calibration records, and quality control data are discoverable. Denton also runs no-refusal periods, when a breath test refusal can turn into a warrant and a blood draw the same night.

    Pretrial programs

    Denton County runs a DWI Treatment Court and a Veterans Court, and its alternative tracks and their DWI eligibility change over time. Whether your case qualifies is one of the first things we check.

    How they prove it

    Marijuana DWI

    Marijuana and edibles can support a DWI without any measurable level.

    The marijuana rules

    Prescription Drug DWI

    A valid prescription is no defense if the medication impaired your driving.

    Prescription rules

    CDL DWI

    A commercial license is disqualified even for a DWI in your own car.

    CDL consequences

    Boating DWI (BWI)

    Operating a boat while intoxicated, prosecuted much like a driving DWI.

    After You Hire Us

    What We Do on Every Case

    From the first call, in order:

    • Request your ALR hearing before the 15-day deadline and use it to question the officer under oath.
    • Demand the dash and body camera video before it is destroyed.
    • Pull the full discovery file: offense report, calibration and maintenance logs, lab records, certifications.
    • Read the underlying chemistry ourselves: the chromatograms and the QC data, not the summary report.
    • Re-score the field sobriety tests against NHTSA protocol, on video.
    • File the motions the evidence supports, because suppression is how DWI cases end.
    • Build your mitigation file, with clinical assessments, at no cost to you.
    • Try the case if the offer is not right. Prosecutors know which firms try cases.

    Intake answers 24/7, and if we can take your case, the consultation with an attorney is free. We quote a flat fee there, so the investment is known before you commit.

    Amazing! Kevin really cared.. my son was not just another money sign. He put his whole heart into getting my son a “Not Guilty” verdict. Denton tried to destroy my son’s career as a police officer and Kevin saw the injustice and was not going to let that happen. He lead a vigorous defense with an amazing team! My son is back doing what he loves! Thank you Kevin and your awesome team!

    Along I-35E

    Serving Lewisville, The Colony, and Corinth

    We defend DWI cases across southern Denton County: Lewisville, The Colony, Corinth, Highland Village, Lake Dallas, Hickory Creek, Little Elm, and Flower Mound. Wherever the stop happened, the case lands at the courts building across the street from our Denton office.

    The Colony. A stop by The Colony PD or by DPS inside the city is prosecuted in Denton like any other Denton County arrest. The Colony sits entirely in Denton County, so there is no county-line question here.

    Corinth and Lake Dallas. The I-35E stretch between Lewisville and Denton produces a steady share of the county’s DWI arrests, from Corinth PD, Lake Dallas PD, and DPS. Those cases are heard in Denton, minutes up the highway.

    The full county walkthrough is on Denton DWI Lawyer, and the building itself on the Denton County courts guide. Facing a non-DWI charge? See Denton Criminal Defense Lawyer.

    Highland Village, Lake Dallas, and Hickory Creek

    The lake towns between Lewisville and Denton along I-35E and FM 2181 are worked by their own police departments and by DPS, and every arrest there is a Denton County case. Our Denton DWI lawyer page covers the courthouse itself.

    The Rest of What We Defend

    DWI is the majority of our work, not all of it. The same attorneys handle these charges in the same courthouses.

    Lewisville

    Lewisville DWI Questions, Answered

    Where is my Lewisville DWI case heard?

    At the Denton County Courts Building, 1450 E. McKinney Street in Denton, not in Lewisville. Misdemeanor DWIs go to the County Criminal Courts at Law, felonies to the District Courts. Our office is directly across the street, and our Denton County guide covers the building.

    I was arrested in The Colony or Corinth. Do you handle that?

    Yes. Every Denton County city prosecutes at the county courts building in Denton. You may sit in a city jail briefly before transfer. Wherever the stop happened, we defend it.

    What's different about Denton's DWI Unit?

    Your prosecutor handles intoxication cases exclusively. That means shortcuts get punished and prepared defenses get respected. We build every Denton County case for a specialist audience, starting with the defenses that actually work.

    How long do I have to save my license after a Lewisville DWI?

    15 days from the notice of suspension to request an ALR hearing, or the suspension is automatic. Inside the window, call today. Past it, an occupational license may keep you driving.

    Can a first DWI end without a conviction?

    It can. Since September 1, 2019, Texas law lets a judge grant deferred adjudication on a first DWI when your alcohol concentration was under 0.15, you have no prior conviction under the intoxication statutes, and you did not hold a commercial license at the time. An ignition interlock is a required condition, and the decision is the judge's, not automatic. Deferred is not a dismissal, but the case ends without a final conviction. It is not available where a child was in the car, or on intoxication assault or intoxication manslaughter. Our guide to deferred adjudication covers who qualifies and what it does to your record.

    Is there a DWI lawyer near me in Lewisville?

    Deandra Grant Law has no Lewisville office. Our Denton office is fifteen minutes up I-35E, directly across the street from the courthouse that will hear your case, which is the proximity that matters. Intake answers 24/7, and if we can take your case, the consultation can be by phone or video.

    What does a DWI lawyer in Lewisville cost?

    It depends on the charge and whether the case is headed to trial, and we are direct about numbers at the first call. If we can take your case, the consultation with an attorney is free, and we offer payment plans. Our fee guide explains what a DWI defense should and should not cost, and How Much Does a DWI Cost in Texas? covers the fines and fees a conviction adds.

    Is a DWI a felony in Texas?

    Usually not the first time. A first DWI is a Class B misdemeanor, or Class A if your alcohol concentration was 0.15 or higher, and a second DWI is a Class A misdemeanor. It becomes a felony with a third offense (third-degree felony, two to ten years), any DWI with a passenger under 15 (state jail felony), intoxication assault (third-degree felony), or intoxication manslaughter (second-degree felony). Our felony DWI guide covers each level.

    What is the legal alcohol limit in Texas?

    0.08 for most drivers, 0.04 for anyone holding a commercial driver license, and any detectable amount for a driver under 21. The number is not the whole story: Texas also defines intoxication as losing the normal use of your mental or physical faculties, so a driver under 0.08 can still be charged, and a 0.08 result can still be challenged on how the sample was taken and tested. See what 0.08 actually means.

    How long can my license be suspended after a Lewisville DWI?

    The administrative suspension comes first. A failed breath or blood test brings 90 days for a first offense, and a refusal brings 180 days. A prior alcohol-related contact in the last ten years raises those to one year and two years. A conviction can add its own suspension of 90 days to a year. Requesting the ALR hearing within 15 days of the notice of suspension is the only way to contest the first one, and an occupational license can keep you driving in the meantime. See our license guide.

    Will I go to jail for a first DWI in Denton County?

    The statute allows it: a first-offense DWI carries 72 hours to 180 days in the county jail, and up to a year if the result was 0.15 or higher. In practice a first offense in Denton County more often ends in a dismissal, a reduction, deferred adjudication where you qualify, or probation, and the jail exposure is what the defense is built to remove. The time you already spent in the Denton County Jail after the arrest counts against any sentence.

    What are the penalties for a first DWI in Denton County?

    A first DWI in Texas is a Class B misdemeanor under Penal Code 49.04, and Denton County prosecutes it at the Denton County Courts Building in Denton, not in Lewisville. The numbers below are the statutory ranges; most first offenses in Denton County that end in a conviction resolve with probation rather than jail time.

    Penalty Standard first DWI (Class B) First DWI at 0.15 or higher (Class A)
    Jail range 72 hours to 180 days Up to one year
    Criminal fine Up to $2,000 Up to $4,000
    State traffic fine on conviction $3,000 $6,000
    ALR license suspension 90 days after a failed breath or blood test, 180 days after a refusal
    Suspension on conviction 90 days to one year
    Ignition interlock At the court's discretion Required as a condition of probation
    Deferred adjudication Available Not available

    The state traffic fine is separate from the criminal fine and is usually the largest single cost of a conviction. None of this applies if the case is dismissed, won at trial, or reduced to a non-DWI offense. Our first-offense DWI guide covers each penalty in detail.

    How do I choose a Lewisville DWI lawyer for a first offense?

    Ask every lawyer you talk to the same five questions. Did they prosecute DWI cases before they defended them? Deandra Grant prosecuted DWI as a Dallas County Assistant District Attorney. How many cases have they tried to verdict? Our attorneys have tried more than 500. Can they read the lab's chromatogram, not just the summary report? Deandra Grant and Douglas Huff are ACS-CHAL Forensic Lawyer-Scientists, and every step of the lab's work on your blood is discoverable. Will they request your ALR hearing inside the 15-day window? We do it on the first day. And do they work at the Denton County Courts Building every week? Our Denton office is directly across the street from the courts building. Our guide to choosing a DWI lawyer goes deeper on each question.

    I was just arrested for DWI in Lewisville. What should I do first?

    Call us before you do anything else, because two clocks are already running. The 15-day window to request an ALR hearing starts when you receive the notice of suspension, and your bond conditions take effect the moment you are released. Write down everything you remember about the stop while it is fresh, keep the paperwork you were handed, and do not discuss the case with anyone but your lawyer. Intake answers 24/7, and if we can take your case, the consultation with an attorney is free.
