Jid, you are not correct about california law. Below is what it says. Div 10 is accidents and Div 11 is rules of the road. Why the gang officers, detectives, and the like can drive unmarked single color cars. As they aren’t enforcing rules of the road as their primary duty.

You are not correct about Cali law. Here is what it says. Div 10 is related to accidents and investigations and Div 11 is rules of the road. That is why “gang unit”, detectives, and the like cars are usually unmarked. They are not primarily enforcing traffic rules or dealing with accidents.
