A second DWI conviction in Texas carries mandatory jail time, a license suspension of at least 180 days, and fines starting at $600 — plus a required ignition interlock device on any vehicle you drive.

Texas treats a second driving while intoxicated offense as a Class B misdemeanor, which is more serious than a first offense but still below felony level. The mandatory minimum is 72 hours in jail (though judges typically impose 30 days or more), and you will lose your license for at least 180 days. You will also pay a fine between $600 and $2,000, plus court costs and fees that vary by county.

The ignition interlock device requirement is automatic — you cannot drive any vehicle without one installed unless the court grants a hardship exception, which is rare. This device measures your breath alcohol before the engine will start. You pay for installation and monthly monitoring, usually $60 to $100 per month.

A second offense also triggers an automatic driver's license suspension that begins when ready when you are arrested, separate from any conviction. You can request a hearing to challenge the suspension within 15 days of arrest, but most people do not succeed. Understanding what happens next and what your options are will help you move through the process with fewer surprises.

Key Takeaways

  • A second DWI in Texas is a Class B misdemeanor with a mandatory minimum of 72 hours in jail, though judges typically impose 30 days or longer.
  • Your driver's license is suspended for at least 180 days, and you must install an ignition interlock device on any vehicle you operate.
  • Fines range from $600 to $2,000, plus court costs and fees that vary by county and can add hundreds of dollars to your total penalty.
  • You have 15 days from arrest to request a hearing to challenge the automatic license suspension, though success is uncommon without legal representation.
  • A second offense within five years of a first conviction triggers these penalties; if more than five years have passed, it may be treated as a first offense instead.

How Texas Counts Prior DWI Convictions

Texas looks back 10 years from the date of your current arrest to count prior DWI convictions. If your first DWI was more than 10 years ago, it does not count toward enhancing your current charge. However, if your first conviction was within the past 10 years, your current arrest is automatically treated as a second offense, even if you have had no other incidents.

The clock starts from the date of arrest on the first offense, not the date of conviction. This matters because convictions can take months or years to resolve. If you were arrested for a first DWI five years ago but did not go to trial until last year, the 10-year window still began from the original arrest date.

Deferred adjudication — a plea deal where charges are dismissed if you complete probation — still counts as a prior offense for enhancement purposes. Many people believe a deferred adjudication "does not count," but Texas law treats it the same as a conviction when determining whether a second offense applies.

Jail Time, Fines, and License Suspension

The mandatory minimum jail sentence for a second DWI is 72 hours, but judges in most Texas counties impose 30 days to 6 months. Some counties are more lenient; others are stricter. The actual sentence depends on factors like your blood alcohol content, whether you refused a breath test, and whether anyone was injured or property was damaged.

Fines start at $600 and can reach $2,000. On top of that, you will pay court costs (typically $200 to $400), a driver's license reinstatement fee ($100), and fees for the ignition interlock device. The total financial penalty often exceeds $3,000 when all costs are added together.

Your license suspension begins when ready upon arrest through an automatic administrative suspension, separate from any criminal conviction. You can request a hearing within 15 days to contest this suspension, but you must act quickly — the important date is firm. Even if you win the hearing, the judge can still impose a criminal suspension as part of your sentence if convicted.

The Ignition Interlock Device Requirement

An ignition interlock device is mandatory on any vehicle you own or regularly drive after a second DWI conviction in Texas. The device connects to your vehicle's ignition system and requires you to blow into a tube before the engine will start. If your breath alcohol registers above a set limit (usually 0.02 percent), the engine will not turn on.

You must pay for installation, typically $100 to $200, and monthly monitoring fees of $60 to $100. The device also records every time you use it, and the data is reported to the court. If you miss a monitoring appointment or the device detects alcohol, the court will be notified and you could face additional penalties.

The interlock requirement lasts for at least 180 days, but judges can extend it to two years or longer depending on the circumstances. You cannot remove the device yourself — a certified technician must do it, and you must provide proof of removal to the court. Some people ask for a hardship exemption to avoid the device, but Texas courts grant these very rarely and only in extreme circumstances.

What Happens to Your Driving Privileges

After your license suspension ends, you will not automatically get your license back. You must visit a Texas Department of Public Safety (DPS) office and pay a reinstatement fee of $100. You will also need to provide proof that you have completed any required alcohol education programs and that the ignition interlock device has been installed (if that is part of your sentence).

Once reinstated, your license will have a restriction code indicating that you must use an ignition interlock device. You cannot drive a vehicle without one, even if you own a second car. The only exception is if the court grants a hardship exemption, which is uncommon.

If you are caught driving without the device installed, or if you drive a vehicle that does not have one, you will face additional criminal charges. This is treated as driving with a suspended license, which carries its own penalties including jail time and fines.

Mandatory Alcohol Education and Treatment Programs

Texas requires anyone convicted of a second DWI to complete an alcohol awareness program, usually called a DWI education program or DWI intervention program. These programs typically run 12 to 32 hours depending on your blood alcohol content and other factors. You must complete the program before your license can be reinstated.

Some courts also order a substance abuse evaluation, which is a separate assessment conducted by a licensed counselor. If the evaluation recommends treatment, you may be ordered to attend counseling or a treatment program as a condition of probation. The cost varies but typically ranges from $300 to $1,000 for the education program alone.

You are responsible for finding an approved program and paying for it yourself. The court will provide a list of approved providers in your county. Failure to complete the program on time can result in your license remaining suspended and additional court action.

Probation and Supervision Terms

A second DWI conviction typically results in probation lasting 2 to 10 years, depending on the judge and the circumstances. During probation, you must report to a probation officer, usually monthly, and comply with all conditions set by the court. Common conditions include the alcohol education program, possible counseling, random drug and alcohol testing, and community service.

You must also avoid any new arrests or violations of probation. A single violation — missing a probation appointment, failing a drug test, or getting arrested for any reason — can result in the judge revoking probation and imposing the full jail sentence that was suspended. This is why probation violations are taken very seriously.

Some courts allow you to request early termination of probation after serving a portion of the term, usually after two to five years of clean compliance. You would need to petition the court and show that you have completed all requirements and maintained good behavior.

How a Second DWI Affects Your Record and Future

A second DWI conviction remains on your criminal record permanently in Texas. It does not disappear after a certain number of years, and you cannot have it sealed or expunged. This means it will show up on background checks for employment, housing, professional licenses, and other purposes.

A second conviction also makes you ineligible for certain jobs, particularly those requiring a commercial driver's license or positions in law enforcement, education, or healthcare. Some professional licenses can be suspended or revoked based on a DWI conviction.

If you are arrested for a third DWI within 10 years, it becomes a felony charge, which carries much harsher penalties including up to 10 years in prison. This is why the consequences of a second offense are serious — they set the stage for felony charges if another incident occurs.

Frequently Asked Questions

Can I get my license back before the 180-day suspension ends?

You can request an occupational license (also called a hardship license) from the court, which allows you to drive to work, school, medical appointments, and alcohol education programs. You must petition the court and show that the suspension causes undue hardship. The court has discretion to grant or deny this request, and approval is not may provide.

What if I refuse the breath test during a second DWI arrest?

Refusing a breath or blood test triggers an automatic license suspension of 180 days for a second offense (compared to 90 days for a first offense). You still have the right to request a hearing within 15 days. Refusal also cannot be used as direct evidence of guilt in court, but it can be used to show consciousness of guilt, and the jury may draw negative inferences from the refusal.

Will a second DWI affect my car insurance?

Yes. Your insurance company will likely increase your rates significantly or drop you entirely. You may be required to file an SR-22 form (proof of financial responsibility) with the Texas Department of Public Safety, which your insurance company must submit. You will need to maintain this filing for at least three years.

Can I get the conviction reduced to a lesser charge?

This depends on the specific facts of your case and the prosecutor's willingness to negotiate. Some second DWI cases can be reduced to reckless driving or another misdemeanor, but this is not automatic and requires legal representation. The sooner you discuss options with an attorney, the better your chances of negotiating a favorable outcome.

What is the difference between a DWI and a DUI in Texas?

Texas does not have a separate DUI charge for adults. DUI applies only to minors (under 21) and refers to any detectable amount of alcohol. For adults, the charge is DWI, which requires proof that you were intoxicated (blood alcohol of 0.08 percent or higher, or impaired by drugs or alcohol). The penalties for a second DWI are the same regardless of whether alcohol or drugs were involved.
