Can police stop my vehicle without a specific reason in England and Wales?

A uniformed police officer has a broad power under section 163 of the Road Traffic Act 1988 to require any vehicle to stop. This power does not require any suspicion that an offence has been committed: the officer can stop any vehicle for any reason or for no stated reason at all.

Once stopped, you must produce your driving licence, certificate of insurance, and MOT certificate if asked. You are not required to carry these with you: you can produce them within seven days at a police station of your choice, which is known as a HORT/1 or "producer." Failure to produce these documents is an offence.

The officer may also require you to undertake a breath test for alcohol under section 6 of the Road Traffic Act 1988, but only if the officer reasonably suspects you have consumed alcohol or drugs, have committed a moving traffic offence, or have been involved in an accident. A breath test cannot be required from any driver at a routine stop without one of these grounds. Refusing to provide a sample of breath when lawfully required is a criminal offence.

If during the stop the officer develops grounds to search you or your vehicle, different powers apply. Section 1 of PACE 1984 allows officers to search vehicles for stolen articles or offensive weapons, subject to the usual requirement of reasonable grounds for suspicion. Certain powers, such as section 60 of the Criminal Justice and Public Order Act 1994, allow searches without individual suspicion in authorised areas.

You should not drive away from a stop while an officer is speaking to you. Once the officer has completed the stop and indicated you are free to go, you may leave. Being uncooperative or aggressive during a traffic stop can complicate the encounter significantly and may lead to further investigation.
