DWI and DUI in San Antonio, TX: the Bexar County court, the deadlines and choosing a lawyer

A drunk driving arrest in San AntonioTexas charges it as DWI, driving while intoxicated — runs on two clocks at once. The criminal case goes to the Bexar County court, and your license is handled separately by the state. That second deadline is the short one, and it does not wait for your court date.

Wording

In Texas it is called DWI, not DUI

DWI stands for driving while intoxicated. Court paperwork, the police report and Texas attorneys all use that term, so searching for a «DUI lawyer» in San Antonio turns up firms describing the same work under a different label.

In Texas the two are separate charges rather than two names for one thing. DWI applies to drivers 21 and over at 0.08% BAC or otherwise intoxicated; DUI is the zero-tolerance offense for drivers under 21, who can be charged over any detectable amount of alcohol.

Where your case goes

Bexar County handles DUI cases from San Antonio

San Antonio lies in Bexar County and its city limits also reach into Comal County and Medina County — if you were stopped on that side of town, the case may be filed there instead. The city has about 1,495,295 residents, and local practice matters more than most people expect: prosecutors in one county run diversion programs that the next county does not offer, and the judges who hear these cases week after week have known preferences on sentencing.

This is the practical argument for hiring locally rather than by search ranking. An attorney who appears in Bexar County regularly knows which prosecutor is handling the docket and what a realistic outcome looks like there — knowledge that does not transfer from a neighboring county.

How common drunk driving cases are in Bexar County

Federal crash records show what the county deals with. It is worth knowing before your first hearing, because it shapes how routinely local prosecutors handle these cases — and how little novelty your argument will have.

Source: NHTSA Fatality Analysis Reporting System, 2020–2022. Counts fatal crashes where police recorded that a driver had been drinking, which is narrower than the federal 0.08 BAC measure and therefore understates the real figure. Bexar County sits above the Texas average. Counties inside one state are broadly comparable, because testing practice is set at state level; comparing across state lines is not, and we do not do it here.

Texas law

What a conviction triggers, whatever the county

These follow the conviction itself and are not negotiable with a prosecutor. Knowing them is how you judge whether fighting the charge is worth the cost.

  • Interlock term: For the duration of the suspension, unless the court finds good cause to remove the device early
  • Lockout threshold: Set by the device standard the Department certifies; the statute does not fix a number
  • Program run by: Texas Department of Public Safety, on the court order
  • Device cost in Texas: not published by Texas — nationally about $70 a month

What each step carries in Texas: first offense penalties in Texas, second offense penalties in Texas and when it becomes a felony penalties in Texas.

Kinds of case

What a San Antonio DWI attorney actually handles

«DWI lawyer» covers several different fights. Which one you are in decides what the first consultation should be about.

First-offense DWIRepeat and felony DWIUnderage and zero-toleranceDrug-impaired drivingRefusing the testChallenging the evidence

What each of these means under Texas law →

Injured by a drunk driver, not charged?

That is a different area of law. A defense attorney represents the person facing the charge; a claim for injuries or the loss of a family member is handled by a personal injury attorney, and the two rarely overlap in one firm. Search for a personal injury or wrongful death attorney in your county rather than a defense lawyer.

Questions

Asked about DWI cases in San Antonio

Where is a San Antonio DWI case heard?

San Antonio sits in Bexar County, so a DWI arrest here is normally prosecuted in that county's court. Some Texas municipalities run their own courts for lesser traffic offenses, and which court you land in affects both timing and local practice — an attorney who appears there regularly will know which.

How much does a DWI lawyer cost in San Antonio?

Fees are set by the individual firm, not by Texas, and vary with whether the case is resolved by plea or goes to trial. Most attorneys give the first consultation free, so the useful first step is establishing what your case actually involves before discussing price.

Do I need a DWI attorney if I plan to plead guilty in San Antonio?

The license side of a drunk driving case moves separately from the criminal case and on a much shorter clock: Texas sets the interlock requirement at length of suspension. Pleading guilty does not pause that deadline, which is why the first consultation is normally about the license, not the plea.

Where do I install an interlock after a San Antonio conviction?

There are 67 certified installers in San Antonio. Texas requires the device to come from a provider the state has approved, so the choice is between approved providers, not between any auto shop.

Attorney advertising. InterlockDeviceNearMe is not a law firm, does not practice law, and does not give legal advice. Nothing here creates an attorney-client relationship. Requesting a consultation connects you with an independent attorney or a legal referral service, who decide separately whether to take your case. Case outcomes depend on facts we do not know, and no result is ever promised. Deadlines in DUI cases are short and vary by state — speak to a licensed attorney in your state before relying on anything you read here.
