Alan,
Clearly all trucks are required to have commercial plates, that's what I was referring to about weight fees. Generally a commercial plate has a different letter/number sequence which would be clearly identifiable to any law enforcement officer. However, a vanity plate on a truck does not prove that it is a commercial vehicle, only the registration will show that. Look at the new "retro" black plates on new trucks, there is no "commercial" identifier. The point I was trying to make was that the CHP doesn't know if a vanity plate or a VOM plate represents a commercial vehicle. The possibility they are going to stop an old truck regarding what plates it has is slim to none, they have better things to do. I see older cars and trucks at shows that are registered with current white/blue plates painted yellow/black, black/yellow, and blue/yellow and nobody really cares.
