FAQ 9: What are the logistics for a permitted load that is transported by more than one mode? For example, a permitted load is transferred to an ocean vessel.

Answer:  The Hazardous Materials Safety Permit is only required for motor carriers. A motor carrier's HM Safety Permit-related responsibilities end when the material is transferred to the next mode.

Subsequently, permit-related responsibilities begin when the motor carrier assumes responsibility for the material.

In the case of the example, above, when the motor carrier has delivered the permitted load to the vessel operator's facility, then the motor carrier's permit-related responsibility ends.
