Regulations change. This page summarises published Ohio rules as reviewed October 2026 and is not legal advice; the conditions printed on your permit control. Note: Escort and time rules are from ODOT Form OS-1A (Rev. 01/18); the ODOT 'Limitations & Provisions' page hides the current text behind accordions so it could not be compared. 2026 holiday dates fetched from ODOT. Where a load meets several escort conditions, a lead and rear are required. Ohio Turnpike and local roads require separate permits. Legal width 8 ft 6 in; total combination length and legal-height statute text only partially verified (13 ft 6 in per ORC 5577.05(D)).
