If you modify the vehicle so that it is “no longer consistent with the registration certificate, you must subject the vehicle to a registration inspection within one month.” (Driving Licence Book, 19th Edition, page 239)
This is to ensure that the traffic safety is not negatively impacted by the modification to the vehicle.
