A driver without a hazardous materials (H) endorsement is transporting a small quantity of hazmat that falls below the federal placarding threshold. Which statement is accurate?

49 CFR 172.504 (placarding thresholds, including Table 1 any-quantity materials); 49 CFR 383.5 (defines 'hazardous materials' as material required to be placarded under 49 CFR part 172, subpart F — this is where the placarding-to-endorsement link actually

Understanding this threshold matters because misjudging it in either direction is costly: driving a placarded load without the endorsement can mean a $5,000-plus fine, an out-of-service order, and CDL disqualification, while wrongly assuming every hazmat shipment needs an endorsement could cause a driver to refuse legal work or a dispatcher to misassign loads.
