Four Totes of Gasoline: Bulk Packaging, Tank Vehicle, and the Endorsement on Your License
You hold a Class A CDL with the hazardous materials (H) endorsement. Your tank vehicle (N) endorsement has not been issued yet; the skills test is scheduled for next month. Dispatch sends you to a fuel distributor to pick up four portable tanks (totes), each with a rated capacity of 265 gallons, filled with gasoline, for delivery 180 miles away to a construction site's refueling station. The shipper's shipping paper reads: "UN1203, Gasoline, 3, PG II," lists four packages, and carries an emergency response telephone number. At the dock the loader tells you, "It's not a tanker, it's just totes on a flatbed - your H endorsement covers it." Each tote shows the proper shipping name and UN number on two sides. The totes carry no hazard labels. You have 9 hours of drive time remaining and the receiver closes at 17:00. The shipper is waiting for you to sign and pull out.
1. May you legally accept and drive this load with only the H endorsement? Walk through the definitions that control the answer.

Two separate definitions must be tested, because they answer different questions.
Bulk packaging (49 CFR 171.8). For a liquid, a bulk packaging is one with a capacity greater than 119 gallons. Each 265-gallon tote is therefore a bulk packaging. That fact alone does not require an N endorsement - it changes marking, placarding, and shipping-paper treatment, not the license class.
Tank vehicle (49 CFR 383.91). A CMV used to transport liquid or gaseous material in a tank with an individual rated capacity over 119 gallons, with an aggregate rated capacity of 1,000 gallons or more, permanently or temporarily attached to the vehicle or chassis, and that requires placarding.
Test the numbers: 4 x 265 = 1,060 gallons, which is at or above the 1,000-gallon aggregate. Placarding is required because gasoline is a Table 2 material and the load is far above the 1,001-lb threshold (about 6,700 lb of product). All three elements are met, so the combination is a tank vehicle and an N endorsement is required.
With H only, you may not drive it. Decline to sign, ask the shipper to hold the load, and get dispatch's reassignment in writing. The loader has confused packaging type with vehicle classification.
2. Assuming you held the N endorsement, what placards would the vehicle need, and would the shipping paper as written be acceptable?

Placards. Gasoline is a Table 2 material (49 CFR 172.504), and the 1,001-lb aggregate threshold is exceeded by a wide margin, so the vehicle must display the FLAMMABLE placard on both sides and both ends. Because these are bulk packagings, the hazard communication rides on the tote markings plus the vehicle placards rather than on individual package labels - the absence of labels on the totes is not by itself a defect, but the markings (proper shipping name and UN number on two sides) and the placards are mandatory.
Shipping paper. Section 172.202 requires the basic description in a fixed sequence: proper shipping name, hazard class, UN identification number, then packing group. The shipper wrote "UN1203" first, so the entry is out of sequence and should be corrected. The paper also needs the total quantity and the number and type of packages covered by the description, plus an emergency response telephone number that is monitored at all times the material is in transit (172.604) - a number that rolls to voicemail at night does not satisfy the rule.
You are entitled to ask the shipper to correct the document before you sign; a driver should not paper over a defective description with a verbal assurance.
