With us at Brighton & Hove Streamline, all our vehicles and drivers are on our special data base. All our vehicles are required to have proof of insurance and a "Condition of Fitness" certificate which is issued when the vehicle has had an enhanced mechanical council inspection. When either of these are due the vehicle receives a daily countdown message (via the vehicle data-unit) warning of the impending expiry date. Should these papers not be produced then the vehicle would automatically be barred from receiving work.
The same happens for driver licenses (taxi & private-hire). Should a driver not produce the expected new licence then he or she is barred from receiving work via the data-unit via the drivers PIN. Drivers also need to have a regular CRB check (Criminal Records Bureau) and pass a Driving Standards Agency test. The licensing officer also has the power to enforce a driver to undertake a DSA test at anytime.
