Study NY DMV CDL-10 Section 6 for combination-vehicle safety: off-tracking and wide turns, rollover prevention, backing, trailer skids and jackknife recovery, trailer air supply and glad hands, fifth wheel and kingpin coupling, tug and visual checks, landing gear, and combination inspection. NY DMV lists a $10 CDL permit-test application fee covering written tests taken together, a $5 fee for other required tests not passed at initial application, and a separate $40 road test fee. Federal CDL rules require at least 80% correct on each knowledge test, and a failed combination-vehicle knowledge test prevents Group A CLP/CDL issuance.
