Jason has had extensive experience working on Passenger Cars, Heavy Vehicles and Motorcycles along with working for the RMS for a three-year period involved with Light and Heavy Vehicle Compliance.

Light vehicle is a vehicle with a gross vehicle mass up to and including 4.5 tonnes, heavy vehicle is greater than 4.5 tonne gross vehicle mass. 

Vehicles must comply with the vehicle standards requirements made for it as of its date of manufacture. A vehicle that is modified must continue to comply with those standards or any later version of those standards that may apply as a result of a particular modification.

Vehicles need to comply with the Australian Design Rules and Schedule 2 of the Road Transport (Vehicle Registration) Regulation 2017 for light vehicles or Schedule 2 of the Heavy Vehicle (Vehicle Standards) National Regulation (NSW) for heavy vehicles.

When testing vehicles with significant modifications tests are often required to be recorded on video, data logged and conducted on closed airport runways.
