Ohio Tire Chain Laws

How Ohio handles chains

Ohio has no chain law for trucks. No DOT posts R-1, R-2, or a Chains Required order. State law exempts chains from the studded-tire rule whenever there's snow or ice on the road (ORC 5589.081), but ORC 5589.08 bars chains on a towed vehicle's tires. Studded tires are legal only November 1 through April 15. In winter you meet county snow emergencies (Level 1, 2 or 3), declared county by county, and Ohio Turnpike bans on long doubles and triples in bad weather. Check OHGO and the county sheriff for road conditions.

When, where, and what counts

• When required: Chains are optional. There is no seasonal activation and no chain-control system. ODOT never posts R-1/R-2/R-3 or 'Chains Required' signs. State law exempts chains from the studded-tire rule when there is snow or ice on the road (ORC 5589.081), but ORC 5589.08 bars chains on the tires of a towed or pulled vehicle. The winter restriction you actually meet is a county snow emergency (Level 1, 2 or 3), declared county by county at the sheriff's request. It is a local travel restriction, not a chain rule, and each county sets what each level means. In Hamilton County, for example, Level 3 closes all roads to non-emergency and non-essential use. Studded tires are limited to November 1 through April 15.
• Where: No mandate anywhere. Voluntary traction on I-90 and I-490 in the Lake Erie snow belt and on I-70/I-71. Ohio has no mountain passes and no chain-control corridors. On the Ohio Turnpike, a Commission rule bars these during high winds or other adverse weather: long combination vehicles (triples and long doubles over 90 feet), high-profile tow-behind trailers other than fifth wheels, campers, boats, enclosed trailers, mobile homes, office trailers and livestock trailers (OAC 5537-3-01(M)). Moves under Turnpike permits can't run in storms or on slippery or snow-covered roads unless the chief engineer waives it (OAC 5537-3-05(C)(3)). These are weather bans, not chain rules.
• Applies to: No CMV chain mandate and no weight threshold. Chains are a driver's choice on any vehicle, except that ORC 5589.08 bars chains on the tires of a towed or pulled vehicle. That clause is not limited to any vehicle type, so it reads as covering a trailer's tires.
• Chains vs traction devices: No traction device is mandated in Ohio. The studded-tire law does not apply to tire chains when there is snow or ice on the road (ORC 5589.081). That exemption does not reach a towed trailer's tires, because ORC 5589.08 bars chains on the tires of any towed or pulled vehicle. Studded tires are permitted Nov 1 to Apr 15. AutoSock is neither required nor prohibited.
• Check the live order: OHGO (ohgo.com), ODOT's travel map, for live conditions. County snow emergency levels come from each county sheriff, and ODOT sends you there for them. Ohio issues no chain-control order to look up.
• Fine: No chain-up fine, because chains aren't required. Chains are exempt from the studded-tire rule when snow or ice is present. Studded tires used outside Nov 1 to Apr 15 are a minor misdemeanor (fine up to $150). Chains on the tires of a towed or pulled vehicle violate ORC 5589.08, also a minor misdemeanor with a fine up to $150 (ORC 5589.99(B); ORC 2929.28). That section dates from 1953 and is titled for traction engines, and no official guidance says how it applies to semi-trailers.
