The NHVR is responsible for regulating heavy vehicle standards, approving heavy vehicle modifications and granting exemptions from compliance with certain standards.
Vehicles that have been designed for a specific or special purpose, vehicles that have been modified, and vehicles that cannot comply with vehicle standards, may need to apply to the NHVR for permission before they can operate on roads.
