Priority regulations for transportation in Texas

The federal DOT drug and alcohol testing program (49 CFR Part 40) is the backbone of transportation compliance. All safety-sensitive employees must undergo pre-employment, random, post-accident, reasonable suspicion, return-to-duty, and follow-up testing. CDL holders must maintain valid DOT medical certificates through the FMCSA National Registry. Hours-of-service regulations intersect with fatigue management and fitness-for-duty concerns. The Clearinghouse database requires employers to query driver records for drug and alcohol violations before hiring and annually thereafter. State-level regulations may add requirements for intrastate carriers, but cannot weaken federal standards.

Recent regulatory updates in Texas

• Capture or Use of Biometric Identifier Act (CUBI) — Employer Compliance

  2025-01-01

  Texas Business & Commerce Code § 503.001 requires employers to obtain informed consent before capturing, collecting, or otherwise obtaining biometric identifiers including fingerprints, voiceprints, and retina or iris scans. Employers may not sell, lease, or disclose biometric data and must destroy it within a reasonable time. Increasing litigation activity underscores the importance of CUBI compliance for employers using biometric timekeeping or access systems.

Transportation compliance FAQ

Do state cannabis laws apply to DOT-regulated employees?

No. DOT regulations explicitly state that state cannabis legalization does not change federal testing requirements. All safety-sensitive employees subject to DOT testing must test negative for marijuana under the 5-panel standard. The DOT issued guidance clarifying that medical marijuana cards do not constitute a legitimate medical explanation for a positive test.

What is the FMCSA Drug and Alcohol Clearinghouse?

The Clearinghouse is a federal database that records DOT drug and alcohol violations for CDL holders. Employers must query the Clearinghouse before hiring a CDL driver and annually for current employees. Drivers with unresolved violations cannot perform safety-sensitive functions. The Clearinghouse went into effect January 2020, and a full query requires driver consent.

How often must DOT random testing be conducted?

FMCSA requires minimum random testing rates of 50% for drugs and 10% for alcohol annually of the covered employee pool. Testing must be spread reasonably throughout the calendar year with unpredictable selection. Each covered employee must have an equal chance of selection in each testing cycle.
