This course covers truck size, weight and permits end to end: why these limits come from Title 23 and the Federal Highway Administration rather than FMCSA, and why the federal rules bind states rather than you; the three weight numbers, why all of them must be satisfied at once, and what the bridge formula and its 36-foot exception are for; why width includes your cargo, why length is a floor for the trailer rather than a ceiling for the rig, and why height has no federal limit at all; how state permits work, which loads can be permitted, and how to plan a multi-state oversize move; and how to read a scale ticket and shift weight. State-specific limits are not listed, because there are fifty sets of them. The course is organized into five modules of short lessons, followed by a final quiz.
