While this is a good idea, it will be fraught with corruption and mismanagement.
There should be certain rules to when you would need to certify your vehicle eg. for public transportation (Taxi's, busses, Uber/Bolt/Taxify) and trucks/cargo movers/couriers you would need to get that done every 6 months, for fleet vehicles yearly, for private vehicles, once the warranty period has expired then yearly or if in the warranty period and involved in an accident then yearly as well
Now the kicker, this should be a free service, as long as your vehicle licence is paid up, there are will be no costs.
