What happens with a second DWI in Hays County?

A second DWI in Hays County is a Class A misdemeanor under the Texas Penal Code, with at least 30 days in jail if the person is convicted. After the arrest, the person is booked and sees a magistrate within 48 hours. The magistrate must then order an ignition interlock as a bond condition, with one narrow exception.

This guide is about what is different the second time someone is charged with driving while intoxicated. If you want the basics of any DWI arrest, from the traffic stop to the 15-day license hearing deadline, start with our guide to DWI bail in Hays County. If you already know you need a bond, our page on DWI bail bonds in San Marcos explains how we post one.

What makes a DWI a “second offense” under Texas law

A DWI becomes a second DWI when it is shown at trial that the person was convicted once before of an offense relating to operating a motor vehicle while intoxicated. Section 49.09 of the Penal Code sets this out.

What counts as the earlier offense

The earlier offense does not have to be a plain DWI from Texas. The law lists what counts, including:

• an earlier DWI, or DWI with a child passenger
• intoxication assault, when the vehicle was a motor vehicle
• an intoxicated driving offense under the law of another state
• older Texas DWI laws that existed before 1994

The same section also treats an earlier conviction for flying, boating or operating an amusement ride while intoxicated as a prior for this level.

Probation and deferred adjudication

Two details catch families off guard. First, a DWI conviction on or after September 1, 1994 counts as final even if the sentence was probated, meaning the person got probation instead of jail time. Second, for this section, being placed on deferred adjudication community supervision for a DWI counts as a conviction.

Is there a time limit on the earlier DWI?

Section 49.09 does not set a time limit on using an earlier conviction to make a new DWI a second offense. A five-year window does appear in the law, but in a separate rule about interlocks after a second conviction, covered below. How an old record applies to a particular case is a legal question, not one a bail bond company can answer.

The charge level and the punishment range for a second DWI in Texas

A second DWI is a Class A misdemeanor with a minimum jail term of 30 days. Under Section 12.21 of the Penal Code, a Class A misdemeanor is punishable by up to one year in jail, a fine of up to $4,000, or both.

How that compares with a first DWI

A first DWI is a Class B misdemeanor, with up to 180 days in jail and at least 72 hours. So a second DWI doubles the maximum fine, raises the maximum jail term from 180 days to one year, and raises the minimum from 72 hours to 30 days. TxDOT puts the second-offense range as one month to a year in jail and a fine up to $4,000, and notes that a separate state fine of $3,000, $4,500 or $6,000 is assessed at sentencing.

When it becomes a felony

A third DWI, with two earlier convictions, is a third-degree felony. So is a DWI after one earlier conviction for intoxication manslaughter. Certain facts can make any DWI a felony regardless of priors, such as a child passenger under 15. Those cases follow a different path, and our page on felony bail bonds in San Marcos covers them.

The ignition interlock bond condition on a second DWI

This is the change most families notice first, because it applies before any trial.

What Article 17.441 requires

Under Article 17.441 of the Code of Criminal Procedure, a magistrate must require a defendant charged with a subsequent DWI to have an ignition interlock installed on the vehicle they own or drive most often. The defendant may not drive any vehicle without one while out on bond. The device must be installed at the defendant’s own expense, before the 30th day after release.

The one exception

The magistrate can leave the interlock off only by finding that requiring it would not be in the best interest of justice. That is the magistrate’s decision. We cannot predict it and will not try.

Monitoring in Hays County

The law lets the magistrate name an agency to check that the device is installed and to monitor it, with a monthly fee capped at $10. Hays County Judicial Services lists ignition interlocks among the devices it monitors, at $10 a month. The county’s pretrial program also uses portable alcohol monitors and an ankle-worn device that detects alcohol in sweat.

After a conviction, a separate interlock rule

A different rule, in Section 49.09(h), applies only after a conviction for a second or later DWI committed within five years of the one before it. The court must then order an interlock on each vehicle the person owns or drives, lasting until one year after the license suspension ends. That is part of the case outcome, not the bond.

Driver’s license consequences, at a high level

A second DWI can cost the person their license for longer than a first. TxDOT lists the loss of a driver’s license for up to two years for a second offense, compared with up to one year for a first.

There are two separate processes: the administrative suspension that starts after a failed or refused breath or blood test, and any suspension that follows a conviction. The deadlines and periods are explained in our DWI bail guide. Which periods apply to a given driver is a legal question.

After a second DWI arrest in Hays County

The process is the same in San Marcos, Kyle, Buda or Wimberley. What changes is mostly what is attached to the bond.

Magistration and bail

Texas law requires that the person be taken before a magistrate no later than 48 hours after arrest, in person or by video. Hays County’s Magistrate Court holds hearings every day of the year and sets bail and bond conditions. There is no set bail for a second DWI. The magistrate weighs factors in Article 17.15, and the person’s criminal history is one of them, so an earlier DWI is part of what the magistrate considers.

Personal bond is still possible

A second DWI is not, by itself, on the lists in Article 17.03 that bar a magistrate from granting a personal bond. Hays County pretrial officers interview people at the jail and make a recommendation, and the magistrate decides. Any interlock order applies whichever type of bond is used.

Court

A second DWI goes to the Hays County Courts at Law, which hear all Class A and B misdemeanors. The jail does not track court dates. The County Clerk’s office handles misdemeanor questions at 512-393-7330.

What a bail bond company can and cannot do here

We can post a surety bond once bail is set, explain what the bond paperwork says, and remind you that the interlock deadline is short. We cannot tell you whether a past case counts as a prior, whether to fight the license suspension, or how the case will end. Those are legal questions, and we do not recommend or suggest lawyers.

What to do next

Call the Hays County Jail bond line at 512-393-7807 to ask whether bail has been set, or use our Hays County Jail inmate search guide to find the person. If the interlock is ordered, plan the installation right away, because the 30 days run from release.
