CDL Required in Texas for Interstate Commerce Under 26,000 lbs?

Yes, in two cases—even if GVWR < 26,001 lbs:

1. Hazardous Materials: Any vehicle transporting HM requiring placarding (49 CFR 383.5).
2. Passenger Transport: Vehicle designed/carrying 16+ passengers (including driver).

Otherwise, for pure property transport under 26,001 lbs GVWR/GCWR in interstate commerce, a CDL is not federally required. However:

• Texas does require a CDL for any vehicle ≥26,000 lbs GVWR or any HM/passenger case above.
• Intrastate TX rules align with federal for HM/passengers.
• Non-CDL drivers still need: valid license, medical card (if >10,000 lbs), USDOT number (if for-hire), compliance with HOS if applicable.

When in doubt, get the CDL—it expands opportunities and avoids violations.
