This equipment requires special assessment and approvals for road transport.
Heavy haulage: Special permits and route assessment required
NHVR guidance says some Class 1 OSOM moves can run under national or state notices. If a notice covers your route and combination, a permit may not be required.
For most jurisdictions, NHVR access applications are lodged through NHVR Go. NHVR also publishes PDF forms for post/fax workflows. NT and WA trips are handled directly by the relevant road authority.
Have the intended route, loaded dimensions, gross mass, vehicle combination, axle details, and confirmation that the load is a large indivisible item. You may also need third-party approvals and supporting documents.
Escort vehicles, police escort, route surveys, bridge checks, travel-hour restrictions, and special operating conditions become more likely at this level. Build time for approvals and route validation into the move plan.
Disclaimer: This calculator provides general guidance only. Actual permit requirements vary by state, route, and load configuration. Always verify with the relevant state transport authority before transport.
