The check usually begins before you have even come to a complete stop. Most modern police vehicles are equipped with Automatic Number Plate Recognition (ANPR) technology. As they follow or pass you, the system automatically scans your registration to check if the vehicle is taxed, insured, and has a valid MOT. If the system struggles to read the characters, it might trigger a manual stop. This is often the first sign that there is an issue, such as what happens if ANPR cameras cannot read your 2D number plate due to dirt or damage.

One of the more technical aspects of a roadside plate check involves looking for specific markings that prove the plate was manufactured to legal standards. Since September 2021, the mandatory standard for new plates has been BS AU 145e. During a check, an officer will look at the bottom right-hand corner of the plate for the British Standard code and the name and postcode of the registered supplier.
