Ohio Axle Regulations

(A)   The maximum wheel load of any one wheel of any vehicle shall not exceed 650 lb. per inch width of pneumatic tire.

(B) The weight of vehicle and load imposed upon a road surface that is part of the interstate system by vehicles with pneumatic tires shall not exceed any of the following weight limitations:

1.      On any one axle, 20,000 lb.

2.      On any tandem axle, 34,000 lb.

3.      On any two or more consecutive axles, the maximum weight as determined by application of the formula provided in division (C) of this section.

(C) For purposes of division (B)(3) of this section, the maximum gross weight on any two or more consecutive axles shall be determined by application of the Federal Bridge formula.

However, two consecutive sets of tandem axles may carry a gross load of 34,000 lb. each, provided the overall distance between the first and last axles of such consecutive sets of tandem axles is 36 feet or more.

The weight of vehicle and load imposed upon a road surface that is not part of the interstate system by vehicles with pneumatic tires shall not exceed any of the following weight limitations:

1.      On any one axle, 20,000 lb.

2.      On any two successive axles:

  • Spaced 4 feet or less apart, and weighed simultaneously, 24,000 lb.
  • Spaced more than 4 feet apart, and weighed simultaneously, 34,000 lb., plus 1000 lb. per foot or fraction thereof, over 4 feet, not to exceed 40,000 lb.

On any 3 successive load-bearing axles designed to equalize the load between such axles and spaced so that each such axle of the 3-axle group is more than 4 feet from the next axle in the three-axle group and so that the spacing between the first axle and the third axle of the 3-axle group is no more than 9 feet, and with such load-bearing 3-axle group weighed simultaneously as a unit:

  • 48,000 lb., with the total weight of vehicle and load not exceeding 38,000 lb. plus an additional 900 lb. for each foot of spacing between the front axle and the rearmost axle of the vehicle.
  • 42,500 lb., if part of a 6-axle vehicle combination with at least 20 feet of spacing between the front axle and rearmost axle, with the total weight of vehicle and load not exceeding 54,000 lb. plus an additional 600 lb. for each foot of spacing between the front axle and the rearmost axle of the vehicle.

4. The total weight of vehicle and load using any combination of axles, other than as provided for 3-axle groups in this section, shall not exceed 38,000 lb. plus an additional 900 hundred lb. for each foot of spacing between the front axle and rearmost axle of the vehicle.
5. The maximum overall gross weight of vehicle and load imposed upon the road surface shall not exceed 80,000 lb.

This section applies to the weight of a vehicle and its load imposed upon any road surface that is not a part of the interstate system by vehicles with pneumatic tires.

Maximum Permit Weight Allowed

All overweight (OW) permit applications are checked for these Axle Weight guidelines. Every axle is checked for each guideline as appropriate or as otherwise noted.

  • Single Axle maximum weight allowed is 29,000 lb.
  • Short Tandem maximum weight allowed is 36,000 lb.
  • Long Tandem maximum weight allowed is 50,000 lb., provided the tandem has a minimum 4'1" spacing, the vehicle has sufficient inner and outer bridge spacing to achieve the requested weight and the vehicle must pass analysis.
  • Short Tri Axle maximum weight allowed is 47,000 lb.
  • Short Quad Axle or Long Tri Axle, maximum weight allowed is 60,000 lb.
  • Long Quad Axle, maximum weight allowed is 80,000 lbs.

Tire Load

For each axle, the maximum weight allowed is the number of Tires, times the tread width of the tire in inches times 800. (Max Lbs. Allowed = #tires on axle * tire tread width in inches*800) (e.g., 2 tires with 11 inch tread width ==> 2*11*800 = 17,600 Lbs.)

Minimum Axle Weight

Every axle except the front axle must have at least 10,000 lb.

Three Axles 16-32. Instead of treating these as two tandem groups, the axle pair with the shorter of the two spacings is analyzed as a tandem group and the third axle as a single axle. If the two spacings are the same, then two analyses are created: (1) 1st axle as single, 2&3 as tandem, and (2) 1&2 as tandem, 3rd as single. If at least one of the analyses pass, then the guideline is satisfied.

3 or Fewer Steel Coils or Aluminum (Single Trip and Continuing) Permit – GVW up to 120,000 lb.

Toledo Port Area

90 Day or 365 Day Continuing permits may be issued to allow a vehicle to make multiple moves between the Michigan/Ohio state line and various port and processing facilities in the Toledo area, hauling "Various Commodities" at Michigan legal weights (up to 154,000 lb.) Each power unit and/or different vehicle configuration will require its own permit.

Delta Steel Complex

90 Day or 365 Day Continuing permits may be issued to allow a vehicle to make multiple moves between the Michigan/Ohio state line and the Delta Ohio steel complex hauling "Steel Products/Raw Materials" at Michigan legal weights (up to 154,000 lb.) and includes the use of load equalizing variable load suspension axles. Permits from local governmental agencies may also be required. Each power unit and/or different vehicle configuration will require its own permit.

Michigan Legal Permits

90 Day or 365 Day Continuing permits allowing an overweight vehicle movement between a specified point in Williams, Fulton or Lucas counties in Ohio and the Michigan border, over prescribed routes. The permitted weight shall be based on the state of Michigan's weight law, with a gross vehicle weight not to exceed 154,000 lb. and shall have sufficient number of axles to meet the Michigan weight law.

 

Ohio Trip and Fuel (IRP / IFTA) Permits

Commercial companies that are not registered for the IRP or IFTA may purchase temporary trip and fuel permits for 12$ per day. This allows you to pass through or operate temporarily within Ohio

Ohio Overweight / Oversize Fines

The minimum fine in Ohio is 100$ and this can skyrocket into thousands of dollar at 3.00$ per 100 pounds once you reach over 10,000 pounds over weight. Additional punishments such as jail, truck and load confiscation can also be a punishment. 

Running Hours and Holiday Restrictions

There are no mentions of light requirements for the hauling commercial vehicle. All pilot cars and escorts must have proper lighting.

Flags, Lights and Banners

Oversized/weight loads under 12' wide may move 7 days a week not including holidays. They may also travel 30 minutes before sunrise and up to 30 mins after sunset.  Once you are over 12' wide you must look to your permit for your hours and days of operations.

Ohio Tire Regulations

The tire tread must have at least 2/32 of an inch of tread or it will be deemed illegal. If the tire shows wires cuts, cracks, or any other internal part it will not pass inspection.

Ohio Annual Permits

Annual permits range from 970$ to 2970$ and are valid for 1 year. Their limis are 140K in weight 14' wide and 14'6 tall to qualify for an annual permit.

Ohio Road Conditions

In roadway work zones, engineers and construction workers make safety their top priority every day—for drivers as well as themselves.

They depend on passing drivers to work on safety, too.

There are always in action alerts across the state of Ohio for speed and accidents and road constructions weather warning and those can be found on the ohgo.com webpage.

Most road constructions and events are ending soon with the possibility for new plans and projects to start, so the state publishes press releases on their official DoT page to inform the public and motorists.

Ohio advocates work zone awareness so that everyone driving or being involved in traffic anyway possible stay's safe, staying focused on the roads, stay as calm as possible, respecting the speed limitations.
