What this test covers

Learn the full coupling and uncoupling sequence step by step; it is one of the most-tested topics.
Always do a tug test after coupling to confirm the fifth wheel has locked onto the kingpin.
Understand off-tracking: the trailer wheels cut inside the tractor's path, so swing wide enough on turns.
Know what causes a jackknife (locked or skidding drive wheels) and how smooth braking prevents it.
Connect and check the glad-hand air lines and the electrical line, and raise the landing gear fully before moving.
Expect MELT and combination-weight questions; confirm your province's exact required training hours.
