Evaluating A Texas Drunk Driving DWI Case and the Deciding Factors.
In most Texas DWI cases, there are 3 pieces of evidence that are open
to interpretation of the law.


Administrative License Revocation

If you have been arrested for DWI, the police officer will serve you with a “Notice of Suspension / Temporary Driving Permit.” The officer is authorized to confiscate your license.

From the date you receive that Notice, you have 15 days to request an Administrative License Revocation hearing on what will otherwise be a mandatory driver’s license suspension. That suspension will last for 90 days for failing a breath or blood test.  The suspension goes up to 180 days for refusing to take a breath or blood test. If this is not your first DWI arrest, then the suspension times increase dramatically.


The ALR hearing is an opportunity to prevent the suspension off your driver’s license. The arresting officer can be subpoenaed to the hearing to provide testimony. If you failed a breath test, you also have the opportunity to subpoena the breath test operator and technical supervisor.

David Frank, Texas represents individuals accused of DWI (Driving While Intoxicated) and DUI (Driving Under the Influence), he has defended against DWI related prosecutions throughout Central Texas.

Getting a DWI (Driving While Intoxicated) is serious! You need to take it seriously – so should your lawyer. Even a conviction for a first-time DWI can carry serious consequences, not the least of which is $1,000 or more per year for three years just to keep your driver’s license.

If you are like the vast majority of those who get arrested for DWI, this is the ONLY way that you would ever have come into contact with the criminal justice system. Only because Texas DWI laws exist, do many people who would never dream of breaking the law find themselves arrested, photographed, fingerprinted, and generally “treated like criminals.” This is serious business. And once you have posted your bond, the whole process is really just beginning.

New DWI Fines

The Texas DWI Surcharge Program has been repealed and replaced. The old law required the Department of Public Safety to assess surcharges on drivers convicted of DWI. House Bill 2048 repealed the DWI Surcharge Program and replaced it with a separate DWI fine. The bill takes effect September 1, 2019.

In addition to the fine prescribed for a person who has been finally convicted of a DWI (not to exceed $2,000 for a class B misdemeanor and up to $4,000 for a class A misdemeanor), the bill requires a person to pay a fine of:

$3,000 for the first DWI conviction within 36 months;

$4,500 for a subsequent DWI conviction within 36 months; or

$6,000 for a first or subsequent DWI conviction if an analysis of a specimen of the person’s blood, breath, or urine shows an alcohol concentration level of 0.15 or more at the time the analysis was performed.

These DWI fines do not include a range.  Instead they are fixed amounts imposed upon conviction by the trial court.  These fines do nothing to accomplish the original intent of the repeal of the Surcharge Program which was “releas[ing] Texans from debt”.  Under the original DWI Surcharge Program, failure to pay surcharges would lead to a driver’s license suspension.

If a person provides information that he or she is indigent, the court may waive all fines and costs imposed on the person.

The new law requires DPS to reinstate any driver’s license that was suspended as of September 1, 2019 if the license was only suspended for failure to pay a program surcharge.

Collateral Consequences

A DWI conviction in Texas carries other consequences as well. For instance, if your insurance company finds out you are convicted of DWI in Texas, then your carrier may drop you or put you in a “high risk” category at a substantially higher cost. Car rental companies may not rent to you if they know you are convicted of DWI. If you have a job that requires you to be under a fleet insurance policy, such as with a shipping / trucking company, you may lose your job if the insurer finds out you have a Texas DWI and drops you. Some DWI convictions require the driver to only operate a vehicle equipped with an Ignition Interlock Device.  The list goes on.

The police report is only the officer’s interpretation.

  • Were you properly read your Miranda warnings?
  • Did the police officer stop you for a valid reason?
  • Were any statements made by you coerced, taken out of context, or misinterpreted?

Important: The Intoxilyzer 5000 assumes that everyone has the same blood breath partition ratio, hematocrit ratio and assumes that all samples are at an air temperature of 93.2 F.  Texas DWI Law does not utilize any methods which would allow for a retest of samples given.  The computer software is proprietary and is not available to scientific peer review.  Many factors can affect a breath test score.  These machines are generally not available for inspections by anyone outside of law enforcement.  Texas does not allow for non-law enforcement or government personnel to become certified as breath test technical operators.  Much of the Texas breath program remains limited to outsiders despite a generally assumed belief that these machines have undergone and passed wide general scientific review.The Intoxilyzer 9000 will soon replace the Intoxilyzer 5000 in Texas.  In other states, the 9000 has had various problems including calibration quality control problems falling below the established tolerance target value.

The Colorado Department of Public Health and Environment issued a report that stated CDPHE could not endorse the test results in 33 involved cases “to remain consistent with laboratory (quality control) best practices.”  The 9000 is not specific for ethanol which means that other substances in the body can test positive for alcohol even when alcohol is not present.  While the 9000 is capable of producing a histogram showing the breath flow, breath volume, blow duration, and breath alcohol concentration, Texas has chosen not to preserve the histogram.  The Intoxilyzer 5000’s valve has been replaced in the 9000 by a valve that can actually go back and forth. This may allow for back-flow contamination from prior breath samples, ambient air, or even the simulator solution.

Field Sobriety Tests:

Police make arrests on the basis of “probable cause.”  This is not the same thing as “proof beyond a reasonable doubt.”  It is not a police officer’s job to determine if someone is guilty.  Many police offers choose to arrest on the basis of caution.There is not a great deal of technical training for a police officer in the field of Texas DWI Law.  There is no law in Texas that requires they keep up their training on a regular basis with respect to standardized field sobriety training.  Many police officers do not make any form of notes on the side of the road with respect to numerous details.  Police officers almost never include mitigating or exculpatory information in their reports, mainly incriminating observations.Were there distractions during the testing?
