There has been some debate between the California Medical Association (CMA) and the California Highway Patrol (CHP) over the necessity of this law. The CHP argues that the law, which was passed in 1954, is outdated and no longer necessary. The CMA argues that in rural areas the law is still needed and could save lives. For now, the law is still on the books and the CMA regularly gives stickers to licensed physicians to use in case of emergencies.
