Traffic police are police officers, units, and agencies who enforce traffic laws and manage traffic. Traffic police include police who patrol highways, direct traffic, and address traffic infractions. They may be a separate agency from a main police agency, a unit or division within a police agency, or a type of assignment issued to officers; they can also be part of a transportation authority or highway authority.

A highway patrol is a police unit, detail, or law enforcement agency created primarily for the purpose of overseeing and enforcing traffic safety compliance on roads and highways within a jurisdiction. They are also referred to in many countries as traffic police, although in other countries this term is more commonly used to refer to foot officers on point duty who control traffic at junctions.
