What endorsement do I need for doubles/triples in New York?
NY DMV lists endorsement code T for Doubles/Triples, and CDL-10 Section 7 says drivers need a Class A CDL and a Double/Triple endorsement before driving a set of doubles or triples.
Is the New York doubles/triples endorsement knowledge-test only?
FMCSA lists Double/Triple Trailers (T) as knowledge test only. NY DMV administers CDL permit and endorsement written tests at DMV offices.

Does ELDT apply just for adding T?
FMCSA and NY DMV ELDT sources list first-time Class A/B CDL, Class B-to-A upgrades, and first-time S, P, or H endorsements. They do not list T as a separate first-time endorsement ELDT trigger, though ELDT may apply to the underlying CDL class or upgrade.
