License class requirement in California

Thanks to all the responses on my situation...my statements still stands as the requirements are per California vehicle code. The issue with DMV is the problem in not having a Class A licensed person accompany me to the skills testing...that is an immediate "fail" on their skill test...this is a direct quote from DMV officials. I'm retired law enforcement and was not aware of the licensing requirements nor are many of my fellow former work partners still actively employed...an obscure requirement but none-the-less a requirement. Hope no one gets caught in the license class ignorance trap because their rig was over the limits for whatever size you pull/drive. Safe travels to all.
