If you are modifying a car, four wheel drive or motor cycle Vehicle Standards Bulletin 14 provides advice on modifications. Following these guidelines will simplify the certification process and save you money.
If you are modifying a truck or bus, Vehicle Standards Bulletin 6 should be followed.
Vehicles can be modified outside the scope of these documents, however the cost of confirming compliance will generally be significantly higher.
