What Texas requires

Texas attaches the interlock to the license itself: when a court order reaches the Department, your driving privilege is canceled on the 30th day after it notifies you, unless you fit a device and obtain a restricted interlock license. The restriction is also mandatory by statute for anyone granted an occupational license after a DWI conviction, whether or not the order spells it out — a judge can waive it only by finding it unnecessary for public safety.

  • First offense: 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

Why Texas orders these devices

An interlock order is not a judgment about you personally — it is what the state does with every case of this kind, and the reason sits in the crash record.

Galveston County, 2020–2022

Source: NHTSA Fatality Analysis Reporting System, 2020–2022. The count covers 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. Galveston County runs above the Texas average, which is part of why the interlock requirement here is enforced the way it is. What the device changes is measurable too: a car fitted with one cannot be started over the limit, which is why the order attaches to driving privileges rather than to the sentence.

Questions

Interlock questions in League City

Where can I get an ignition interlock device installed in League City, TX?

We index 5 certified installation points in League City, run by Intoxalock, Smart Start, LifeSafer and others. Addresses are listed above. Book with the provider your paperwork names, not the nearest one — a device approved in one state is not automatically approved in the next, and switching brands mid-term means a second installation fee.

How much does it cost to have an ignition interlock device installed in Texas?

Texas does not publish a price, so the honest answer is the national one: NHTSA puts installation at $70 to $90 and monitoring at about $70 a month, roughly $3 to $4 a day. Quotes in League City will sit around that unless the provider is charging for something the state does not require.

Can I drink one beer and still start the car in Texas?

Almost certainly not. Texas does not print one fixed number in the statute — the level is set by the certifying agency in the device standard, typically between 0.02% and 0.025% BAC, far below the 0.08% driving limit. The device is not testing whether you are impaired, it is testing whether you drank. One drink shortly before a test is enough on most programs, and the fail is recorded whether or not you try again.

What does an ignition interlock device do?

An ignition interlock is a breath-alcohol tester wired into your car ignition. You blow into it before starting the engine; if your breath alcohol is above the state threshold, the engine will not start.

While you are driving, the device asks for rolling retests at random intervals. Every sample, skipped test, and lockout is recorded and sent to the agency monitoring your case.
