The tested knowledge aligns with FMCSA Part 383 requirements: assembly and hookup, converter dolly use, proper placement of the heaviest trailer, coupling and uncoupling, inspections, air and electrical lines, rearward amplification, rollover and jackknife prevention, traffic-space issues, and emergency handling.
