Allen DWI with CDL Lawyers

The FMCSA Clearinghouse

Since January 2020, the Federal Motor Carrier Safety Administration operates a Clearinghouse under 49 CFR Part 382. The Clearinghouse is a federal database tracking drug and alcohol testing violations for CDL holders. Employers are required to:

• Query the Clearinghouse before hiring a CDL driver;
• Query the Clearinghouse annually on existing CDL employees;
• Report drug and alcohol violations to the Clearinghouse;
• Prohibit employment in safety-sensitive functions for drivers with unresolved Clearinghouse violations.

A DWI conviction, a refusal, a positive drug or alcohol test, or an employer’s “actual knowledge” of a violation triggers a Clearinghouse entry. Until return-to-duty is completed under 49 CFR Part 40 Subpart O, the CDL holder is effectively unemployable in safety-sensitive CDL positions.

Return-to-Duty Under 49 CFR Part 40 Subpart O

A CDL holder with a DWI or drug/alcohol testing violation who wishes to return to CDL driving must complete a federally mandated return-to-duty process:

• Substance Abuse Professional (SAP) evaluation by a qualified SAP, not any counselor or therapist.
• Completion of SAP-prescribed treatment and/or education. The SAP, not the driver, determines what is required.
• SAP follow-up evaluation confirming compliance.
• Return-to-duty test administered by a designated employer representative and not the SAP.
• Follow-up testing for a minimum of 12 months, and up to 60 months, with at least six tests in the first 12 months.

The process takes months at minimum, costs thousands of dollars, and requires employer cooperation which is difficult to secure while the driver is unemployable due to an unresolved Clearinghouse entry. Many CDL holders describe this process as more burdensome than the criminal case itself.

Texas CDL DWI Criminal Penalties

On top of the federal CDL consequences, the underlying Texas criminal DWI penalties apply:

First-Offense DWI (Class B misdemeanor)

• 72 hours to 180 days in county jail.
• Fine up to $2,000.
• Transportation Code § 709.001 statutory fine of $3,000 ($6,000 if BAC 0.15+).
• Driver’s license suspension of 90 days to 1 year under § 521.344.
• Separate CDL disqualification of 1 year under 49 CFR § 383.51.

First-Offense DWI with BAC 0.15+ (Class A misdemeanor)

• Up to 1 year in county jail.
• Fine up to $4,000.
• Transportation Code § 709.001 statutory fine of $6,000.
• Mandatory ignition interlock under CCP Article 17.441.
• 1-year CDL disqualification under 49 CFR § 383.51.

Repeat DWI

Penal Code § 49.09 repeat DWI provisions apply to CDL holders the same way they apply to non-CDL drivers. A second DWI is a Class A misdemeanor with a mandatory minimum 5-day jail term as a condition of probation. A third DWI is a third-degree felony with a mandatory minimum 10-day jail term as a condition of probation. On the CDL side, a second DWI conviction triggers lifetime disqualification under § 383.51.

ALR and CDL Consequences

The Administrative License Revocation process runs parallel to the criminal case, and the CDL consequences of an ALR action can be identical to the consequences of a criminal conviction:

• Failed test (BAC 0.08 or higher in personal vehicle; 0.04 in commercial vehicle): ALR suspension of 90 days on first offense and longer for repeats.
• Refusal: ALR suspension of 180 days on first offense and 2 years on repeats.
• The ALR deadline to request a hearing is 15 days from the notice of suspension. Missing the deadline results in automatic suspension.
• An ALR suspension of a regular driver’s license typically disqualifies the CDL in parallel. The CDL is not separately reinstatable while the regular license is suspended.

For a CDL holder, the ALR hearing is especially critical because it is often the only meaningful opportunity to challenge the initial basis for the stop, detention, and testing before the criminal case reaches its first setting.

How CDL DWI Cases Are Defended

Acquittal-Focused Strategy

Because the federal masking prohibition limits the protection that deferred adjudication or reduction can provide, many CDL DWI cases focus aggressively on acquittal or pre-trial dismissal. This changes the resource allocation on the defense side because the middle-ground resolution options are less available.

Forensic Attack on the Breath and Blood Testing

Ethanol analysis via GC-FID has multiple attack points: sample collection, preservative balance, chain of custody, calibration, column chemistry, retention time, internal standards, and measurement uncertainty. 

Reduction to Non-DWI Offenses

In some cases, reduction to a non-DWI offense (obstruction of a highway or passageway, reckless driving) can avoid CDL disqualification entirely. Unfortunately, these options are not typically offered by the Collin County Criminal District Attorney’s Office.

Fourth Amendment and CCP Article 38.23 Suppression

Stops, detentions, field sobriety testing, arrests, and blood warrants are all subject to constitutional review. Suppression motions frequently dispose of DWI cases.

ALR Litigation as Discovery Tool

Requesting the ALR hearing and taking testimony from the arresting officer months before the criminal trial produces discovery that shapes the criminal defense strategy (and sometimes produces admissions or inconsistencies that defeat the state’s criminal case).

Where Collin County CDL DWI Cases Are Heard

First-offense misdemeanor CDL DWI cases in Collin County are filed in the Collin County Courts at Law. Repeat DWI cases (§ 49.09(a) Class A second DWI or § 49.09(b)(2) third-degree felony third DWI), DWI with child passenger (§ 49.045), Intoxication Assault (§ 49.07), and Intoxication Manslaughter (§ 49.08) are filed in the Collin County Criminal District Courts at the Collin County Courthouse, 2100 Bloomdale Road, McKinney. The Collin County Criminal District Attorney’s Office prosecutes all criminal cases in Collin County. Federal matters (rare in CDL DWI but relevant in certain interstate trucking cases) are filed in the U.S. District Court for the Eastern District of Texas, Sherman Division.

Frequently Asked Questions

I was in my personal car, not the truck. Does my CDL still get disqualified?

Yes. 49 CFR § 383.51 triggers CDL disqualification for DWI convictions in any vehicle — commercial or personal. The 0.04 BAC limit applies only when operating a commercial motor vehicle, but the CDL disqualification applies to any DWI conviction.

Can I get deferred adjudication on a CDL DWI?

No. The federal masking prohibition under 49 CFR § 384.226 bars states from allowing dispositions that prevent a CDL holder’s DWI conviction from appearing on the driving record or being transmitted to other states. HB 3582 deferred adjudication, which works for ordinary first-time misdemeanor DWI cases, does not protect a CDL in the same way. A separate defense strategy (focused on dismissal, acquittal, or reduction to a non-major offense) is usually needed.

How long will I lose my CDL?

First DWI conviction (or first test refusal): 1 year (3 years if transporting hazmat). Second DWI conviction (or second test refusal): lifetime, with possible reinstatement after 10 years under § 383.51(b) Table 1. Reinstatement is discretionary — some drivers never return to commercial driving.

What is the FMCSA Clearinghouse?

The Clearinghouse is a federal database that tracks drug and alcohol testing violations for CDL holders under 49 CFR Part 382. Employers are required to query it before hiring and annually thereafter. A DWI, refusal, positive test, or actual-knowledge violation produces a Clearinghouse entry that effectively prevents CDL employment until return-to-duty is completed under 49 CFR Part 40 Subpart O.

What is return-to-duty?

A multi-step federally mandated process for CDL holders with DWI or drug/alcohol violations: Substance Abuse Professional (SAP) evaluation; SAP-prescribed treatment; SAP follow-up evaluation; return-to-duty test; follow-up testing for 12 to 60 months. The process takes months at minimum, costs thousands of dollars, and requires employer cooperation.

Can I get my CDL back after a second DWI?

Reinstatement after the federal lifetime disqualification is possible under § 383.51(b) Table 1 after 10 years, subject to completion of a rehabilitation program. Whether reinstatement is actually granted is discretionary. Many CDL holders with a second DWI never return to commercial driving.

Contact Our Allen CDL DWI Attorneys

For a CDL holder, a DWI arrest often looks like the end of a career. With the right defense strategy (one that takes the federal regulatory overlay seriously from the first week) it does not have to be. The window for aggressive early defense, for thoughtful ALR litigation, for forensic investigation of the state’s test results, and for acquittal-focused preparation is finite. Waiting does not help.
