Ohio • United States of America
The Ohio Department of Transportation (ODOT) manages over 19,000 centerline miles of highways at the crossroads of America, with more major highway junctions than any other state. Key freight corridors include I-70, I-71, I-75, I-76, I-80, I-90, and the Ohio Turnpike. Ohio is second only to Illinois as a freight crossroads, with Columbus, Cleveland, Cincinnati, and Toledo serving as major logistics centers. ODOT administers commercial vehicle permits, manages Ohio GO, the state's traffic information system, and operates the Ohio Turnpike for commercial trucking. The department collaborates with the rail and air cargo sectors to facilitate multimodal freight movement through this critical corridor.

Notable Rules
Ohio is a critical Midwest freight crossroads with I-70, I-71, I-75, and I-80/90 (Ohio Turnpike) as primary corridors. OHGO (ohgo.com) provides real-time traffic and road condition data for commercial vehicles. Oversize loads on the Ohio Turnpike require a separate Turnpike permit in addition to the state OS/OW permit.
