Will an Out-of-State DWI Count Against Me if I’m Charged With DWI in Texas?

 Posted on April 30, 2026 in DWI / DUI

An out-of-state DWI or DUI conviction can count against you if you are charged with DWI in Texas. Texas does not limit prior offenses to convictions that happened within the state. If you were convicted of an impaired driving offense anywhere in the country, Texas prosecutors can use that conviction to make your current charge more serious and push for harsher penalties.

If you are facing a DWI charge in 2026 and have a prior conviction from another state, a San Antonio, TX DWI defense lawyer can help you understand exactly how that history affects your case and what can be done about it.

How Does Texas Handle Out-of-State DWI Convictions?

Texas law does not require a prior conviction to have happened in Texas for it to count toward enhancing your current charge. What matters is whether the out-of-state offense was substantially similar to a Texas DWI offense. Under Texas Penal Code § 49.09, prior convictions for offenses in other states that prohibit operating a vehicle while intoxicated can be used to elevate the level of your current Texas DWI charge.

Most states have impaired driving laws that are similar enough to Texas law that prosecutors can and do use them as priors. Whether you were convicted of DUI in California, OWI in Indiana, DWI in New York, or another equivalent offense somewhere else, that conviction follows you to Texas.

Does Texas Have a Lookback Period for Prior Convictions?

Unlike some states that only count prior convictions within a certain number of years, Texas has no lookback limit. A conviction from 10, 20, or even 30 years ago can still be used to enhance your current charge.

This means that someone who was convicted of DUI in another state many years ago, moved to Texas, and has stayed out of trouble since then can still face enhanced penalties if they are arrested for DWI here today.

What Are the Penalties for a Repeat DWI in Texas?

How your current charge is classified depends on how many prior convictions you have. Here is how the penalties break down under Texas Penal Code § 49.09:

• A first DWI is a Class B misdemeanor carrying 72 hours to 180 days in jail and a fine of up to $2,000.

• A second DWI is a Class A misdemeanor carrying 30 days to one year in jail and a fine of up to $4,000.

• A third or subsequent DWI is a third-degree felony carrying two to 10 years in prison and a fine of up to $10,000.

On top of these penalties, repeat offenders face longer license suspensions and mandatory ignition interlock device requirements. A felony conviction also creates a permanent record that can affect employment, housing, and professional licenses for years to come.

Can an Out-of-State Prior Conviction Be Challenged?

An out-of-state prior conviction can be challenged. This is one of the most important things to examine in a repeat DWI case. Not every out-of-state conviction qualifies as a comparable offense under Texas law. An attorney can look closely at the elements of the prior offense and compare them to what Texas law requires. If the out-of-state offense is not substantially similar to a Texas DWI, it may not be usable as a prior.

It is also worth examining how the prior conviction was obtained. If you were not properly advised of your rights, did not have legal representation, or the conviction resulted from a procedural error, it may be possible to challenge whether that conviction can be used to enhance your current charge at all. This is sometimes called attacking the prior, and it can mean the difference between a misdemeanor and a felony.

Does a Prior Out-of-State DWI Conviction Affect Bail in Texas?

Judges consider your full criminal history when setting bail, including out-of-state convictions. A prior impaired driving conviction signals to the court that this is not a one-time situation, which can lead to higher bail amounts and stricter release conditions such as ignition interlock requirements or alcohol monitoring devices.

Having an attorney at your bail hearing who can speak to your community ties, your employment, and your overall history can make a real difference in how bail is set and what conditions are attached to your release.

Can the Current Texas DWI Charge Still Be Fought if You Have Convictions From Another State?

Having a prior conviction does not mean the current charge cannot be challenged. The state still has to prove every element of the current DWI beyond a reasonable doubt, and all of the standard defenses remain available. These include challenging whether the traffic stop was lawful and questioning the reliability of the breath or blood test. Your attorney will be examining whether field sobriety tests were administered correctly. They will also determine whether proper procedures were followed during the arrest.
