From 1 July 2017, all private hire cars used to provide chauffeured services must display a pair of tamper-evident[1] decals on the front and back windscreen of their vehicles. This is to allow for easier identification of registered private hire cars, and facilitate enforcement[2] against offences such as unregistered cars providing chauffeured services, or private hire cars picking up passengers by street-hail.
The tamper-evident decals will be inspected when private hire cars undergo regular vehicle inspections.[5] Owners of private hire cars that fail these inspections will not be allowed to renew their road tax.
