Under 49 CFR 383.119(h), what must a tank endorsement applicant know specifically for drivers of DOT-specification tank vehicles?

49 CFR 383.119(h)

DOT-specification tank vehicles (used for certain hazardous or regulated cargo) have periodic retest and marking rules under separate DOT regulations; a tank endorsement holder operating one of these vehicles needs to know these requirements exist even if the detailed schedule lives elsewhere.
