Which shipment does not require a hazardous-materials endorsement solely because of its cargo?
Correct answer: A – A shipment that requires no placards and contains no select agent or toxin listed in 42 CFR part 73
Federal CDL rules require an H endorsement for designated hazardous material that must be placarded and for any quantity of a select agent or toxin listed in 42 CFR part 73. Vehicle weight and intrastate travel do not eliminate that requirement. Another person’s endorsement does not authorize an unendorsed driver to operate the vehicle.
