Looks like Queensland will have some concessions.
As of 1st Nov 2012, Queensland TMR vehicle modification legislation will implement & commence transitioning to the National Code Of Practice (NCOP) over a 6 month period, at which point we will see the revocation of the current QCOP legislation.
Both the new NCOP and older QCOP will run concurrently for 6 months until 1st May 2013, then the older QCOP will be retired, at which point all future vehicle construction & modification legislation will need to meet the requirements of NCOP.
If you have any vehicle modifications which have been made and installed based around the older QCOP legislation (and not yet approved by an engineer with TMR approvals), you should start to make plans to have these approved before the older legislation is phased out in May next year. That's assuming any modifications you've made were engineered for legal road use.
This one is good for us...
