A roadworthiness certificate is issued for a vehicle when it completes a roadworthiness test. The certificate indicates the result of the test, any irregularities detected and, if the vehicle passes the test, a notification of the date of the next roadworthiness test. This certificate is a proof of test. The customer is issued a printed version of the certificate, and an electronic version is stored in the Ministry of Infrastructure register of registered vehicles.
