How Refusing a DWI Test Can Affect Your CDL in Houston

Refusing a DWI test in Houston can put your CDL at risk. A refusal may lead to a driver’s license suspension and, for a CDL holder, at least one year of commercial driving disqualification.

Houston is a major transportation and freight hub in Texas. Its highways, including I-10, I-45, and I-610, carry thousands of commercial vehicles each day.

For a truck driver, losing the right to operate a commercial vehicle can mean losing more than driving privileges. It can affect a job, income, and plans for the family. If you’ve been arrested, a seasoned CDL DWI attorney in Houston can help you understand what happens next and whether you have grounds to challenge the administrative action.

Understanding CDL Laws in Texas

Texas treats CDL holders differently because commercial drivers have added responsibilities on the road. The rules can apply even when the DWI-related incident involves a personal vehicle rather than a truck.

The Federal Motor Carrier Safety Administration (FMCSA) lists refusing an alcohol test under an implied-consent law as a major offense. For commercial driver’s license (CDL) holders, a test refusal carries the exact same immediate penalties as testing positive for alcohol or driving under the influence.

What Happens When You Refuse A DWI Test?

A refusal doesn’t simply disappear because no breath or blood result was obtained. Texas law allows consequences to follow the refusal itself.

Temporary Driving Privileges

After an arrest, you may receive a DIC-24 or DIC-25 notice explaining the action against your license. The paperwork matters. It tells you what DPS is alleging and what you need to do next.

For a standard adult refusal, Texas DPS lists a 180-day suspension for a first ALR refusal and a two-year suspension for a second refusal.

The situation can be more complicated for CDL holders because a commercial disqualification may apply alongside the regular driver’s license suspension.

CDL Disqualification

The federal rules are serious here. According to the Federal Motor Carrier Safety Administration, a CDL holder can be disqualified for one year for refusing a required alcohol or drug test. The law also provides for a three-year disqualification in certain cases involving hazardous materials.

A qualifying second incident can result in lifetime disqualification. Texas Transportation Code § 522.081 also provides for lifetime disqualification after certain combinations of two or more qualifying incidents.

Texas DPS says a driver generally has 15 days after being served with an ALR notice to request a hearing. Miss that deadline, and the request can be denied.

What to Do Next After a CDL DWI Arrest

Don’t assume that refusing the test means the case is over or that nothing can be done.

1. Read the paperwork carefully: Look for the ALR notice, dates, and stated reason for the suspension or disqualification.
2. Protect the hearing deadline: If you’re eligible for an ALR hearing, Texas DPS generally requires the request within 15 days of being served.
3. Check your CDL status: A license suspension and CDL disqualification can involve different consequences.
4. Get legal advice quickly: A lawyer can review how the stop, arrest, test request, and refusal were handled.

There’s also a separate issue for drivers who refuse a DOT drug or alcohol test at work. FMCSA says such a refusal generally carries the same immediate removal from safety-sensitive duties as a failed test, followed by the required return-to-duty process.

Final Thoughts

A DWI test refusal can create serious problems for a Texas CDL holder. The consequences may include a driver’s license suspension, a one-year or longer CDL disqualification, and potentially lifetime consequences after qualifying repeat incidents.

The safest approach is not to ignore the paperwork. Deadlines move quickly, and your CDL may be tied directly to your livelihood.
