What Happens After a First-Time DWI Arrest in Houston?

The hours and days following a DWI arrest can significantly affect your case. Understanding what happens next allows you to protect your rights and avoid mistakes that could make your situation more difficult.

Traffic Stop and Investigation

Most first-time DWI cases begin with a traffic stop. If an officer suspects impairment, they may ask questions, observe your behavior, administer field sobriety tests, or request a breath or blood sample before deciding whether to make an arrest.

Arrest and Booking

If the officer believes there is probable cause, you may be arrested and taken to jail for booking. During this process, law enforcement records your personal information, photographs, fingerprints, and the details of the alleged offense before you are released on bond or remain in custody.

Driver's License Suspension Process (ALR)

In addition to the criminal case, you may also face an Administrative License Revocation (ALR) proceeding. This separate civil process determines whether your driver's license will be suspended because of a failed or refused chemical test. 

You generally have 15 days from the date of your arrest to request an ALR hearing and preserve your driving privileges.

Criminal Court Proceedings

Your criminal case proceeds separately from the ALR process. Depending on the evidence, your case may involve arraignment, pretrial hearings, plea negotiations, motions challenging the evidence, or a trial. An experienced DWI lawyer can guide you through every stage while protecting your constitutional rights.

Can You Refuse a Breath or Blood Test in Texas?

Texas drivers are subject to the state's implied consent law, which means refusing a chemical test can have serious consequences. 

While you have the right to refuse in certain situations, doing so does not necessarily prevent law enforcement from obtaining evidence or pursuing DWI charges.

Implied Consent Law

Under the Texas Transportation Code, anyone who operates a motor vehicle on a public roadway is considered to have given implied consent to provide a breath or blood specimen if lawfully arrested for DWI. Refusing a test may trigger administrative penalties even if you are never convicted of the criminal charge.

Consequences of Refusing a Breath Test

Refusing a breath test does not automatically result in a DWI conviction, but it can still lead to significant consequences, including:

  • Administrative driver's license suspension through the Administrative License Revocation (ALR) process.
  • The refusal being introduced as evidence in court.
  • Additional legal proceedings to challenge the license suspension.
  • Increased complexity when defending your case.

You generally have 15 days from the date you receive notice of suspension to request an ALR hearing and challenge the suspension.

When Police Can Obtain a Blood Sample

In some situations, law enforcement may obtain a blood sample even if you refuse testing. This may occur when officers obtain a search warrant signed by a judge or when Texas law otherwise authorizes a blood draw under specific circumstances. 

Blood samples are commonly sought in cases involving serious crashes, suspected intoxication offenses with aggravating factors, or when a warrant is issued after a refusal.

How Refusal May Affect Your Case

Refusing a chemical test does not automatically make the prosecution's case stronger or weaker. In some cases, the lack of a breath or blood test can make it more difficult for prosecutors to prove intoxication. 

In others, they may rely on officer observations, field sobriety tests, body camera footage, witness testimony, and other evidence to support the charge. 

What Are the Penalties for a First-Time DWI in Texas?

A first-time DWI is generally charged as a Class B misdemeanor under Texas law. However, the penalties can still be severe and may increase if aggravating factors are present.

Jail Time

A conviction may result in:

  • A minimum of 72 hours in jail for most first-time offenses.
  • At least six days in jail if an open container of alcohol was present in the vehicle.
  • Up to 180 days in county jail, depending on the circumstances of the case.

Criminal Fines

The court may impose:

  • Criminal fines of up to $2,000 for a standard first-offense DWI.
  • Court costs and mandatory fees.
  • Additional state-imposed surcharges and program costs that increase the overall financial impact of a conviction.

Driver's License Suspension

A first-time DWI conviction or an unsuccessful ALR case may lead to:

  • Suspension of your Texas driver's license.
  • Requirements to obtain an occupational driver's license in some cases.
  • Additional reinstatement fees before your full driving privileges are restored.

Additional Court-Ordered Requirements

The court may also require:

  • Community supervision (probation).
  • Community service.
  • Completion of a DWI education program.
  • Installation of an ignition interlock device in certain cases.
  • Alcohol or drug evaluations and recommended treatment.

Long-Term Consequences

A first-time DWI conviction can continue affecting your life long after the case ends by causing:

  • A permanent criminal record.
  • Increased automobile insurance premiums.
  • Difficulty obtaining employment or professional licenses.
  • Problems with housing and educational opportunities.
  • Negative effects on your personal and professional reputation.

When Can a First-Time DWI Become a More Serious Charge?

Not every first-time DWI is charged the same way. Certain circumstances can increase the severity of the offense and expose you to significantly harsher penalties.

BAC of 0.15 or Higher

If chemical testing shows a blood alcohol concentration (BAC) of 0.15 or higher, a first-time DWI may be charged as a Class A misdemeanor, carrying increased penalties compared to a standard first offense.

Open Container in the Vehicle

Having an open container of alcohol in the passenger area of the vehicle at the time of the arrest increases the minimum jail sentence, even for a first offense.

Child Passenger Under 15

Driving while intoxicated with a passenger younger than 15 years old is charged as a state jail felony, regardless of whether it is your first DWI arrest.

Accident Causing Injury or Death

If an impaired driving incident results in serious bodily injury or death, prosecutors may pursue more serious charges such as intoxication assault or intoxication manslaughter, both of which carry substantial prison sentences and other severe consequences.

Can a First-Time DWI Be Dismissed or Reduced?

Yes. A first-time DWI charge does not automatically result in a conviction. Depending on the facts of your case, your attorney may be able to challenge the prosecution's evidence, negotiate a reduction in charges, or seek dismissal.

Illegal Traffic Stop

Law enforcement must have reasonable suspicion to stop your vehicle. If the stop violated your constitutional rights, evidence obtained afterward may be excluded from court.

Inaccurate Breath or Blood Test Results

Breathalyzers and blood tests are not infallible. Improper calibration, testing errors, contamination, or mistakes in handling samples can affect the reliability of the results.

Field Sobriety Test Errors

Field sobriety tests are influenced by many factors unrelated to alcohol, including medical conditions, fatigue, uneven pavement, weather, or improper instructions from the officer. We carefully evaluate whether these tests were administered correctly.

What Should You Do After a First-Time DWI Arrest?

The decisions you make immediately after your arrest can significantly affect your case. Taking the right steps early can help protect your rights and improve your defense.

  1. Remain Silent: You have the constitutional right to remain silent. Politely decline to answer questions about the incident until you have spoken with an attorney.
  2. Request an ALR Hearing Immediately: You generally have only 15 days from the date of your arrest to request an Administrative License Revocation (ALR) hearing. Missing this deadline could result in an automatic driver's license suspension.
  3. Preserve Evidence: Write down everything you remember about the traffic stop, including where it occurred, what the officer said, whether field sobriety tests were administered, and whether any witnesses were present. This information may become valuable later.
  4. Contact a Houston First-Time DWI Lawyer: The earlier an attorney begins working on your case, the more opportunities there are to preserve evidence, challenge the prosecution's case, and protect your driving privileges.
