How does CVC 40800(A) apply to federal law enforcement officers who have arrest/detention powers to enforce State Law
but are not primarily tasked with enforcement of the vehicle code?
CVC 40800(A): A traffic officer on duty for the exclusive or main purpose of enforcing the provisions of Division 10 (commencing with Section 20000) or 11 (commencing with Section 21000) shall wear a full distinctive uniform, and if the officer while on duty uses a motor vehicle, it must be painted a distinctive color specified by the commissioner.
