The General Knowledge test every CDL applicant takes (inspection, space management, hazards, cargo, night and winter driving), laid out page by page and ready for the DMV.

The Combination Vehicles test for Class A: trailer air lines, rollover risk, coupling and uncoupling, drawn step by step.

Straight-line backing, offset backing, parallel parking and the alley dock, seen from above, so you know where the trailer goes before you're in the yard.
