Modifications to heavy vehicles

If you make any modifications or changes to a commercial heavy vehicle or trailer that may affect the structural integrity or safety of vehicle the change will need to be approved by the Department of Planning, Transport and Infrastructure.

Your submission for approval must be prepared by a recognised engineering signatory. 

The first table lists all recognised engineering signatories in South Australia along with their recognised fields of work.  The second table describes the approval codes.
