What does 397.101-113 require?

A carrier transporting a highway route controlled quantity of Class 7 material must operate over preferred routes (Interstate System highways and State-designated routes) that reduce time in transit, must prepare a written route plan with the origin, destination, routes, estimated departure and arrival times and telephone numbers for emergencies before departure, give it to the driver and keep it for two years, and must ensure the driver has been trained in the 397 requirements and the route. The carrier must also notify the Nuclear Regulatory Commission or the shipper as required for such shipments, and the States may designate routes under the Subpart D procedures.
