Which endorsement or endorsements must your CDL carry before you may drive a tanker loaded with hazardous materials?

Answer options

Why

A tank vehicle (N) endorsement covers hauling liquids or gases in bulk tanks, and a hazardous materials (H) endorsement covers hazmat cargo, so a tanker carrying hazardous materials needs both. The two are often issued together as one combined X endorsement.
