You need to obtain special certification as evidence that your vehicle complies with the Low-volume Vehicle Code, which includes emissions standards. A low-volume vehicle (LVV) certifier will inspect your vehicle and fit your vehicle with LVV plates as evidence that your engine or exhaust system complies. Find out more about the LVV certification process.
