A dated certificate of radioactive materials training must be:

• A. Carried by the driver
• B. Kept on file at the shipper
• C. Displayed on the dashboard
• D. Available on request

Answer: (A)

Proof of hazmat training must be carried by the driver. This dated certificate shows you’ve completed the required training and is the immediate proof inspectors need to verify you’re authorized to transport radioactive materials. Having it with you lets you present it during any roadside inspection or official request without delay, which is why carrying it is required rather than keeping it only at the shipper’s site or merely having it “available” somewhere else. The date on the certificate confirms the training is current, meeting the recency requirements.
