What is Part 356?

A formerly active motor carrier routing regulation section that is now reserved/repealed.

Current Status

Current eCFR shows Part 356 as reserved after repeal effective May 30, 2025.

Former Rule

Former Part 356 explained older route-authority concepts such as municipalities, communities, and traversal authority.

Routing Authority

Part 356 is reserved, but modern authority, permit, hazmat, and route restrictions still matter.

Commercial Zones

Commercial-zone questions should now be checked under active rules like Parts 372, 368, 365, and state law.

Traversal Authority

Traversal authority is mainly historical language from older route-authority regulation.

What to Check Now

Use current authority, insurance, permit, hazmat, state, and local route checks instead.

Common Mistakes

Do not treat old Part 356 text as active law or assume repeal removed route restrictions.

Carrier Checklist

A practical checklist for current eCFR status, active authority, related rules, route restrictions, and documentation.

Real-World Risk

Old routing assumptions can still create modern authority, permit, hazmat, and route-compliance problems.

Need help checking authority and route compliance before dispatch?

DispatchHQ helps carriers review authority status, insurance, BOC-3, UCR, state permits, hazmat routing, commercial-zone limits, equipment fit, and load paperwork so outdated routing assumptions do not create modern compliance problems.
