First DWI Penalties in Dallas, Texas

Quick Answer: First DWI Penalties in Dallas

A first DWI in Dallas, Texas, is usually charged as a Class B misdemeanor, punishable by up to 180 days in jail, a $2,000 fine, and license suspension.

If the driver’s BAC is 0.15% or higher, the charge is enhanced to a Class A misdemeanor with increased penalties.

In Dallas County, most first-time DWI cases are resolved through deferred adjudication, reduced charges, or dismissal rather than jail time.

This guide explains exactly what penalties apply to a first DWI in Dallas, how Dallas County courts handle these cases in practice, and what most first-time defendants can realistically expect.

Key Takeaways

Most first DWIs are Class B misdemeanors
BAC ≥ 0.15 elevates the charge to Class A
Deferred adjudication is the most frequent outcome in Dallas County. Jail is uncommon.

What Is a First DWI in Dallas, Texas?

A first DWI in Dallas, Texas refers to a first-time Driving While Intoxicated charge prosecuted under Texas Penal Code §49.04 in Dallas County criminal courts.

A case is considered a “first” DWI only if there are no prior DWI convictions, not merely no prior arrests.

Important clarifications:

Deferred adjudication counts as a prior for future DWI enhancements
Dismissed cases generally do not count as prior offenses
Out-of-state DWIs may count as priors under Texas law

Comparison: First DWI Penalties in Dallas

Charge Level	BAC Range	Maximum Jail	Maximum Fine	Common Dallas Outcome
Class B DWI	0.08–0.149	Up to 180 days	Up to $2,000	Probation or deferred adjudication
Class A DWI	≥ 0.15	Up to 1 year	Up to $4,000	Probation with stricter conditions

Texas Law vs Dallas County Practice

Texas DWI penalties are set by statewide statute, but how those penalties are applied depends heavily on local court practice.

Texas law authorizes jail for first DWIs
Dallas County courts rarely impose additional jail time for first-time offenders
Pretrial resolution and compliance matter more than punishment ceilings

Understanding this distinction is critical to accurately assessing risk.

How Texas Law Classifies a First DWI

Under Texas law, a person commits DWI if they operate a motor vehicle in a public place while intoxicated. “Intoxicated” means either:

A BAC (blood alcohol concentration) of 0.08% or higher, or
Loss of normal mental or physical faculties due to alcohol, drugs, or both

A BAC of 0.15% or higher triggers an automatic enhancement, even for first-time offenders.

Class B vs Class A First DWI in Dallas

Class B First DWI (Most Common)

Most DWIs in Dallas County are charged as Class B misdemeanors. This applies when BAC is 0.08%–0.149%.

Statutory penalties include:

Jail: Up to 180 days
Fine: Up to $2,000
License suspension: 90 days (if ALR lost)
Probation: Up to 2 years

Dallas County reality: Most defendants do not serve additional jail time beyond arrest and booking. Time already served typically satisfies any minimum jail requirement.

Class A First DWI (BAC ≥ 0.15)

When a driver's BAC is 0.15% or higher, the charge is elevated to a Class A misdemeanor.

Enhanced penalties include:

Jail: Up to 1 year
Fine: Up to $4,000
License suspension: 90 days
An ignition interlock device is often required
Probation: Up to 2 years

Dallas County reality: Even in enhanced cases, jail is uncommon when the case resolves through probation or deferred adjudication.

The Two Separate Cases Every First DWI Triggers in Dallas

A DWI arrest in Dallas creates two independent legal proceedings.

1. The Criminal DWI Case

Handled in Dallas County criminal courts and determines:

Guilt or innocence
Jail or probation
Fines and criminal record consequences

2. The ALR License Suspension Case

Handled by the Texas Department of Public Safety and determines:

Whether your license is suspended
Completely independent of the criminal case

The ALR Deadline Timeline

Day 0: Arrest
Days 1–15: Deadline to request ALR hearing
Around Day 40: Automatic license suspension if no request is made

If you miss the 15-day deadline, your license will be suspended automatically—even if the criminal case is later dismissed.

Usually no. Most first-time DWI defendants in Dallas County do not serve additional jail time beyond the initial arrest and booking. Any minimum jail requirement is typically satisfied by time already served.

Is a first DWI in Dallas a felony?

No. A first DWI is almost always a misdemeanor. It is charged as a Class B misdemeanor, unless the BAC is 0.15% or higher, which elevates it to a Class A misdemeanor. Felony DWIs generally require prior convictions or aggravating factors like injury.

Class B DWI: Up to 180 days in jail and a $2,000 fine

Do first-time DWI cases in Dallas usually result in probation?

Yes. Deferred adjudication or probation-based outcomes are the most common resolutions for first DWI cases in Dallas County, assuming there are no aggravating factors.

What is deferred adjudication for a first DWI in Dallas?

Deferred adjudication allows a defendant to plead guilty or no contest, but the judge does not enter a conviction. If all conditions are met, the case is dismissed, but it still counts as a prior DWI for future enhancements.

Will I lose my driver’s license after a first DWI in Dallas?

Not immediately. You can usually drive for about 40 days after an arrest. If you fail to request an ALR hearing within 15 days, your license will be automatically suspended. Even if suspended, most people qualify for an Occupational Driver’s License.

If you do not request an ALR hearing within 15 days of your arrest, the Texas Department of Public Safety will automatically suspend your license, typically starting around day 40 after arrest.

Is a BAC of 0.15 treated differently in Dallas?

Yes. A BAC of 0.15 or higher enhances a first DWI from a Class B to a Class A misdemeanor, increases fines, and often results in stricter probation conditions and an ignition interlock device requirement.

How long does a first DWI case take in Dallas?

Most first DWI cases in Dallas County take 6 to 12 months to resolve. The majority end during pretrial rather than at trial.

Can a first DWI be dismissed in Dallas?

Breath or blood testing
Search warrants or constitutional violations

Dismissals are less common than probation outcomes, but are absolutely possible.

Does refusing a breath or blood test affect first DWI penalties?

Refusing testing can trigger a 180-day ALR license suspension, but it may also create defense opportunities if a blood draw warrant was improperly obtained or delayed.

The total cost typically ranges from $6,000 to $15,000+, including attorney fees, bond, court costs, classes, insurance increases, and ignition interlock expenses.
