If your vehicle fails the CVRT, you must have the vehicle repaired and re-tested within 21 days or before 4000km, whichever comes first. A visual re-test does not incur a charge but if an equipment re-test is required a charge is applicable. All details are printed on the fail statement issued by the test centre. If you do not re-test within the 21 days or 4000km, a full test will be required and will incur the full test fee again.
