Details

This guide tells you how to avoid the top 10 reasons that heavy trailers and other vehicles in the O3/4 inspection category fail the IVA inspection.

Full compliance with this guide doesn’t guarantee a pass. You’ll need to view the IVA Inspection manual for the full requirements and testing procedures needed to get your trailer passed.

You must apply for vehicle approval if you’ve:

• built a trailer
• rebuilt a trailer
• radically altered a trailer
• imported a trailer

Vehicles in the O3/4 category are defined as trailers designed and constructed for the carriage of goods, and weigh over 3.5 tonnes.
