What DOT Exemption notation is used when a shipment is authorized under the terms of a DOT exemption?

• A. The phrase 'EXEMPT'
• B. A special permit number from the state
• C. A DOT Exemption Number (like DOT E-1234)
• D. The shipment is not allowed without full compliance

Answer: (C)

When a shipment is authorized under a DOT exemption, the notation used is the DOT Exemption Number (for example, DOT E-1234). This number identifies the exact exemption and the specific conditions under which the material may be shipped, and it must appear on shipping papers and appropriate markings as required. Using the word “EXEMPT” alone doesn’t identify the particular exemption or its terms, so it isn’t sufficient notation. A state-issued special permit is a different authorization and isn’t the DOT exemption notation. The exemption allows the shipment under its terms rather than being outright prohibited, so the correct notation is the DOT Exemption Number.
