State context
CDL requirements in California
The CDL knowledge tests are federal. What California changes is the process around them — where you apply, what it costs, how the skills test is scheduled, and whether longer combination vehicles are permitted at all.

Longer combination vehicles in California
California does not permit LCV operation. Every other jurisdiction prohibits LCVs. The 1991 ISTEA freeze bars any state from adding routes or raising LCV weights, so a driver in a non-listed state cannot obtain LCV authority there at all — tell them that rather than sell them a practice test.
