900 Pounds of Acetone and an Expired H
Andre holds a Class A CDL. His H endorsement expired yesterday, and his renewal appointment is next week. His dispatcher offers him a run carrying 18 non-bulk drums of acetone, total weight 900 lb, from a warehouse to a manufacturer 300 miles away. Acetone is a Class 3 PG II flammable liquid. The shipper's papers show that the material is not a hazardous waste, not a marine pollutant, and not in a reportable quantity. The aggregate gross weight is below the Table 2 placarding threshold, and the shipper says no placards are required. No placards are displayed on the trailer. Andre's Class A CDL itself is valid, and his medical certificate is current. He tells the dispatcher he cannot take the load because his H endorsement has lapsed. The dispatcher says the load is too small to need placards, so the H endorsement should not matter. Andre is unsure and calls you.
1. Does Andre need a current H endorsement for this 900-lb acetone load? Explain the placarding threshold.
Read the worked answer
No, not for this load. The H endorsement is required to operate a CMV carrying hazardous materials for which placarding is required. Acetone is a Class 3 PG II flammable liquid, a Table 2 material. For Table 2 materials, placards are generally required when the aggregate gross weight is 1,001 lb or more. The load is 900 lb, the shipper says it is not a hazardous waste, not a marine pollutant, and not in a reportable quantity, and no placards are displayed. On those facts, the load does not require placards, so the H endorsement is not required. Andre's expired H endorsement does not make this particular run illegal.
2. Andre's H endorsement expired yesterday. Can he legally make the run, and what should the carrier verify before dispatch?
Read the worked answer
He can legally make this run if his Class A CDL and medical certificate are valid and the load truly does not require placards. The expired H endorsement bars him from placarded hazmat, not from all freight. The carrier should verify the shipping papers and the actual weight, confirm the material is not a hazardous substance in a reportable quantity, not hazardous waste, and not a marine pollutant, and confirm no placards are required or displayed. If any of those facts change, the analysis changes. The carrier should also document the review, because a roadside officer will look at the shipping papers and placards, not at the driver's explanation.
3. What if the load were 1,100 lb and the shipper provided placards? How would your answer change?
Read the worked answer
Then the load would require placarding, and Andre would need a current H endorsement. At 1,100 lb, the aggregate gross weight exceeds the 1,001-lb Table 2 threshold, so placards would be required unless a specific exception applied. With an expired H endorsement, Andre could not legally drive the load. The carrier would need to assign a driver with a valid H endorsement or wait until Andre's renewal is complete. The presence of placards is the key trigger; once the vehicle must be placarded, the H endorsement requirement applies regardless of the driver's Class A license.
