How Much Does a DWI Cost in Houston, Texas?

A first DWI conviction in Texas usually costs somewhere between $10,000 and $20,000 once everything is added up, and very little of that is the fine a judge hands down. The largest pieces are the lawyer, the $3,000 state fine that comes with a conviction, and three or more years of higher insurance. Most of the bill hangs on one word, conviction, which is why the cheapest DWI is the one that never becomes one.

Two of those, the state fine and the insurance, are bigger than the criminal fine on almost every case we see. Both only happen if you’re convicted.

The $3,000 state fine, and how to avoid it

The old Driver Responsibility surcharges, a yearly payment for three years, were repealed in 2019. What replaced them is a one-time fine under Transportation Code § 709.001(b): $3,000 on a first conviction within 36 months, $4,500 on a second or later one, and $6,000 whenever the analysis showed 0.15 or more. It’s charged on top of the criminal fine, not instead of it.

Read the trigger carefully. The fine applies to a person “finally convicted.” A dismissal doesn’t trigger it, an acquittal doesn’t, and neither does deferred adjudication, because deferred isn’t a final conviction. On a first DWI under 0.15 without a commercial license, deferred has been available since 2019, and keeping a client from a final conviction is worth $3,000 before anything else is counted.

If you are convicted, § 709.001(c) requires the court to waive the whole state fine on a finding that you’re indigent, and subsection (d) lists what proves it: a tax return or wage statement showing household income at or below 125 percent of the federal poverty guidelines, or proof of benefits like SNAP. The court doesn’t make that finding on its own. Someone has to ask.

What a Houston DWI lawyer costs

DWI defense in Houston generally runs from about $5,000 for a first offense resolved without a trial to $15,000 or more for a case that’s tried or has aggravating facts: a crash, a high number, a child in the car, a prior. Most DWI lawyers, including us, quote a flat fee so you know the number before you start.

What moves the price is how much work the case needs. Litigating the stop, challenging a blood result with an expert, running the ALR hearing, and preparing for a jury all take time. A lawyer who does DWI defense every day costs more than one who dabbles in it. On most cases the difference comes back in fines and insurance, and in a record that stays clean.

Your license: $125, or a hearing

A DWI arrest starts an administrative license suspension separate from the criminal case. You have 15 days from the notice to request an ALR hearing. Miss it and the suspension takes effect on its own, and getting the license back costs a $125 reinstatement fee under Transportation Code § 524.051.

Win the hearing and there’s no suspension and no fee; subsection (b) waives the fee when the suspension isn’t sustained. Lose it and you may need an occupational license to keep driving to work. Either way the hearing puts the arresting officer under oath months before trial, which is worth more to the criminal case than the $125. Our page on what happens at an ALR hearing covers it.

Insurance and the SR-22

Insurance is usually the largest single cost of a conviction, and it’s the one people budget for least. A DWI moves you into a high-risk tier for at least three years, and some carriers look back further. On top of that, a conviction-based suspension doesn’t end until your carrier files proof of liability insurance with DPS, the SR-22, and under Transportation Code § 601.056(c) that filing can’t be released until two years after it was first required. Our page on how long a DWI affects your car insurance goes through the numbers.

Ignition interlock

The interlock is a breath unit wired into your ignition, and you pay for the installation and a monthly lease. Under Code of Criminal Procedure Art. 42A.408(c), a judge must order one as a condition of probation if the analysis showed 0.15 or more, if the DWI is a second or later offense, or if you have a prior intoxication conviction within the last ten years. Art. 17.441 separately requires one as a condition of bond on a repeat offense, a child-passenger DWI, or an intoxication assault or manslaughter charge. On an ordinary first DWI it’s up to the judge.

There’s an upside worth knowing. Six months on an interlock as a condition of probation cuts the wait to seal a DWI conviction from five years to two under Government Code § 411.0731(f). Our page on how long a DWI stays on your record explains that trade.

Bail

On a first DWI in Harris County, most people are released on a personal bond without paying a bondsman. Bail goes up with priors, a crash, a child passenger or a felony charge. Our page on how much bail is for a DWI in Texas has the details.

Probation costs

If you’re placed on probation, the judge sets a monthly supervision fee between $25 and $60 under Art. 42A.652, and can waive or reduce it. You’ll also pay for the DWI education program, which Art. 42A.403 requires you to finish within 180 days, and for any drug or alcohol testing, counseling, or victim impact panel the judge orders. On a first DWI, probation can run up to two years, so the monthly costs add up.

The cost that doesn’t end

Every number above stops eventually. A conviction doesn’t. A Texas DWI conviction can’t be expunged, and it enhances any future DWI for the rest of your life. It also shows up on background checks when you apply for a job or an apartment, and professional licensing boards see it too. Nurses, teachers, pilots and commercial drivers feel that one most.

That’s the case for spending money on the defense. A dismissal or an acquittal takes most of the list above off the table, and deferred adjudication takes a big share of it, the state fine included.
