57. Police

Police are public authorities responsible for enforcing laws, maintaining public safety and managing situations that may affect road traffic. In traffic, police officers may control vehicles, enforce traffic rules, investigate collisions, direct traffic and respond to emergencies.

Road users must follow lawful instructions given by police officers or other authorised traffic-control personnel. Police directions may temporarily override traffic lights, road signs or normal traffic arrangements, depending on local law.

What is the role of police in road traffic?

Police help enforce traffic law, investigate collisions and respond to risks on the road. For example, Greater Manchester Police describe targeted road enforcement, a round-the-clock roads-policing response and specialist serious-collision investigation. Exact responsibilities and powers vary by jurisdiction.

Must you obey a police officer directing traffic?

Yes. Lawful directions given by an authorised police officer must be followed. In many countries, those directions take precedence over traffic lights, road signs and normal priority rules.

What should you do if police signal you to stop?

Slow down, follow the officer's directions and stop at a safe location as instructed. Do not make sudden movements or continue driving unless directed to do so.
