What does 49 CFR 392.9b (Prohibited transportation) require?

Short answer

49 CFR 392.9b requires a commercial motor vehicle providing transportation in interstate commerce to not be operated without a safety registration and an active USDOT Number.

The rule says

"A commercial motor vehicle providing transportation in interstate commerce must not be operated without a safety registration and an active USDOT Number." (49 CFR 392.9b(a))

In plain English

This rule is about making sure that commercial vehicles operating across state lines have the necessary safety registration and USDOT Number. It's a basic requirement for ensuring that vehicles are properly regulated and safe to be on the road. Without this registration and number, a vehicle can't legally operate in interstate commerce. In practice, this means that motor carriers need to make sure their vehicles are properly registered and have an active USDOT Number before they can start operating.

What to do

• Verify that your commercial motor vehicles have a safety registration
• Ensure that your vehicles have an active USDOT Number
• Check that your vehicles are properly marked with the USDOT Number
• Keep records of your vehicles' safety registrations and USDOT Numbers up to date
