California does not issue license plates for TCs, they are considered cargo.
After years of reading on this subject, I am of the belief in California the Code says the rear license plate must be displayed in the rear of the vehicle. You may not duplicate the license plate. It cannot be obstructed, and cannot be moved to the vehicle cargo. It must be illuminated.
Based on my belief above, I further believe it is not legal to haul my 1988 Bigfoot 11.5 in California. I base this on the fact the rear of the TC drops down so far you can only see the trailer receiver from the rear of the truck. The photo gives you an idea.
I typically violate the law by moving the license plate to the rear of the TC. There have been times I have not moved the plate. I have never been questioned either way.
