A shipper asks to place 80 pounds of one allowed hazardous-material class and 90 pounds of another allowed class on a bus because there is no other practical shipping method. What is the best analysis under Tennessee Section 4?

1. It may be within the quantity limits only if the materials are otherwise allowed and all rules are met
2. It is automatically illegal because any hazmat amount is forbidden
3. It is automatically legal because each class is below 500 pounds
4. It is legal only if placed in the doorway
