Ohio commercial vehicle weight limits follow the federal Interstate standard of 80,000 lbs gross, 20,000 lbs per single axle, and 34,000 lbs per tandem axle group. The federal bridge formula (23 U.S.C. 127) applies on all routes. Ohio imposes seasonal (spring) weight restrictions on non-Interstate roads typically from late February through mid-April.
