What a Texas DWI Actually Costs, Start to Finish

The number people quote for a Texas DWI is usually a guess. This one is not.

Below is the itemized estimated cost of a first-offense conviction, line by line, adding to about $9,295. Every figure comes from the same source, and the total uses the high end of each range.

What matters just as much is what the total leaves out. Three costs are excluded because they cannot be estimated reliably, and one of them is larger than the entire figure. Any page that gives you a number without telling you what is missing from it is giving you half an answer.

The Full Cost Stack, Itemized

Most people ask what the fine is. The fine is rarely the problem.

A DWI conviction produces a stack of separate obligations, owed to different parties, arriving at different times, and running for different lengths. Some are one-time. Some renew monthly for years. Here is the full stack, in the order it tends to arrive:

Two observations about that list matter more than any single figure in it.

The recurring lines dominate the one-time lines. A fine is paid once. Interlock rental, monthly supervision fees, and elevated insurance premiums renew, and they renew for months or years. That is why the total is so much larger than the number people expect.

Insurance is usually the biggest single line, and it is the one nobody plans for. The Manual’s own first-offense cost table treats increased insurance over five years as the largest entry in the stack, larger than the fine, the court costs, and the super fine combined, and it puts the increase in the range of 300 to 500 percent. That cost is invisible at sentencing and arrives quietly, months later, on a renewal notice.

Fines and Court Costs by Offense Level

Two separate money judgments attach at conviction, and people routinely confuse them.

The statutory fine is capped by the offense classification. A Class B misdemeanor first offense carries a fine of up to $2,000. A Class A, which is where a second offense or a 0.15 or higher first offense lands, carries up to $4,000. A felony DWI carries up to $10,000. Those are ceilings, not automatic amounts.

The state “super fine” is separate and larger. Effective September 1, 2019, the Legislature repealed the DPS surcharges that had been levied on people convicted of DWI and replaced them with a new fine under Transportation Code §709.001:

• $3,000 for a first DWI
• $4,500 where there is a prior DWI
• $6,000 where the DWI involved a BAC of 0.15 or higher

This is assessed in addition to the ordinary fine, on people who are “finally convicted.”

Two qualifications on that, and the second one is the most useful thing on this page.

First, the provision is understood to apply to offenses occurring on or after September 1, 2019, though the bill is not entirely clear on the point.

Second, and more consequential for the typical reader: the super fine appears not to apply to a probated sentence at all. The position taken by Texas prosecutors is that the “finally convicted” language limits the super fine to jail cases and excludes any probated sentence. Since most first-offense DWI convictions resolve in community supervision rather than jail, the $3,000 figure that dominates published cost articles may not apply to the reader at all.

That is worth checking rather than assuming in either direction. It is also a reason to be skeptical of any cost article that adds $3,000 to a first-offense total without asking how the case resolved.

Court costs are set separately from fines, vary by court and by county, and are assessed at disposition. See Texas DWI Penalties for what attaches at each offense level.

Interlock and Monitoring Costs

An ignition interlock is usually the first recurring cost to arrive and one of the last to leave.

It can attach twice: as a condition of bond, which starts within days of arrest and runs until the case resolves, and again as a condition of probation. In a 0.15 or higher case, interlock as a bond condition is mandatory. In a second-offense case it is effectively unavoidable.

The costs come in three parts: an installation charge, a monthly rental and monitoring fee, and a removal charge at the end. The monthly fee is the one that matters, because it multiplies by the number of months the device stays on the vehicle, and in a case with a long probation term that is where the number gets large. Continuous alcohol monitoring devices, where ordered instead of or alongside interlock, work the same way and generally cost more per day.

The two variables you actually control are the length of the term and whether monitoring is ordered at all, both of which are litigated rather than fixed.

What these devices are and how they work day to day is on Alcohol Monitoring.

Insurance and the SR-22

This is the line that outlasts everything else in the case.

An SR-22 is not insurance. It is a certificate your insurer files with the state confirming you carry the required coverage, and the requirement to maintain it typically runs for years after the case ends. The filing itself is inexpensive. The premium behind it is not.

A DWI conviction moves you into a risk category that reprices your policy, and the Manual’s cost table puts that increase in the range of 300 to 500 percent, sustained over five years. Some insurers decline to renew at all, which means shopping the policy from a weaker position. Because this cost lands after sentencing rather than at it, it is almost never included in the number people have in their heads when they decide how to resolve a case.

That timing is the argument for treating the criminal outcome as a financial decision and not only a legal one. The difference between a conviction and a dismissal or a reduction is not a fine. It is years of premiums.

The mechanics are on SR-22 Insurance and the longer picture on DWI and Car Insurance.

Probation, Classes, and the Evaluation

Community supervision is where the small recurring charges live, and collectively they are not small.

Monthly supervision fees. The Manual’s first-offense estimate uses $60 per month, and a 24-month probation term at that rate comes to $1,440 over the life of the supervision. That single line frequently exceeds the fine.

The alcohol evaluation. Texas DWI probation generally requires a substance abuse evaluation early in the term. The evaluation has its own cost, and it carries a second, larger financial consequence: whatever treatment it recommends becomes a condition, and treatment costs more than the evaluation that ordered it.

The DWI education course. A required class with a fixed fee, paid by the defendant.

The additions. A victim impact panel, a Crime Stoppers donation, and community service hours are common conditions. The first two cost money directly. Community service costs time, which for hourly workers is money.

DWI probation carries more conditions than almost any other Texas criminal offense, which is precisely why the running cost is higher than people expect. What supervision actually involves is on DWI Probation.

Getting the License Back

The license costs arrive in two waves and are easy to underestimate because they are spread out.

During the suspension, an occupational license carries a filing fee and, in most cases, the cost of having a lawyer prepare and present the petition. It restores legal driving, but it is a proceeding, not a form.

At the end of the suspension, reinstatement requires a fee paid to DPS, proof of insurance, and the SR-22 filing. Reinstatement is not automatic when the suspension period ends; it happens when you complete the requirements and pay.

The trap here is timing. People assume driving privileges return on a date. They return on a transaction, and a person who does not complete it can spend months believing they are licensed when they are not.

The process is on Getting Your License Back and the occupational license on Occupational Driver’s License.

What a Lawyer Costs Is a Different Question

Everything above is the cost of a conviction. What it costs to hire a defense lawyer is a separate question with a separate answer, and mixing the two produces a number that is useless for either decision.

The distinction matters because the two move in opposite directions. Defense fees are money spent to reduce the stack above. A case that ends in dismissal or a reduction removes the super fine, the probation fees, the interlock term, the education requirements, and in many cases the years of elevated premiums. That is the actual comparison worth making, and it is not fee versus zero.
