All rules as provided by section 5577.08 of the Revised Code shall be made by the board of county commissioners, at regular meetings, by a majority vote. Such rules shall be kept on file in the office of the board and open for inspection by the public.

At least two days before such rules become effective the board shall cause to be placed and retained on county and township highways classified under section 5577.08 of the Revised Code or sections thereof, and on any bridge classified under section 5577.08 of the Revised Code, at both ends and at any points of intersection, signs, of substantial construction, which will conspicuously indicate the limitations of weight of vehicle and load or speed which will be allowed on such highways or bridges.

It shall be unlawful to operate upon such highway or bridge a vehicle whose maximum weight or speed is in excess of the limitations prescribed.

Any driver or operator of a commercial car, trailer, or semitrailer may obtain from any person, firm, partnership, corporation, or association, including the owner, lessee, or operator of such commercial car, trailer, or semitrailer, owning and operating sealed scales in this state, a written "statement of gross vehicle weight" showing the gross weight of the vehicle including the cargo on the vehicle, the name and address of the person issuing the statement, and the date and place where the vehicle and its cargo were weighed. The driver or operator of the commercial car, trailer, or semitrailer shall retain such statement of gross vehicle weight on his person, and any law enforcement officer of this state may request that such driver or operator exhibit it to him. If, upon examining the statement of gross vehicle weight, the law enforcement officer has reason to believe that the information contained therein is correct in every respect, he shall indorse it with his name and the date and place where it was exhibited to him. The law enforcement officer may then permit such driver or operator to proceed without weighing by a law enforcement officer of this state. No person shall willfully issue a written statement of gross vehicle weight and knowingly give any false information in such statement.

Section 5577.11 | Wheel protectors.
 

No person shall drive or operate, or cause to be driven or operated, any commercial car, trailer, or semitrailer, used for the transportation of goods or property, the gross weight of which, with load, exceeds three tons, upon the public highways, streets, bridges, and culverts within this state, unless such vehicle is equipped with suitable metal protectors or substantial flexible flaps on the rearmost wheels of such vehicle or combination of vehicles to prevent, as far as practicable, the wheels from throwing dirt, water, or other materials on the windshields of following vehicles. Such protectors or flaps shall have a ground clearance of not more than one third of the distance from the center of the rearmost axle to the center of the flaps under any conditions of loading of the vehicle, and they shall be at least as wide as the tires they are protecting. If the vehicle is so designed and constructed that such requirements are accomplished by means of fenders, body construction, or other means of enclosure, then no such protectors or flaps are required. Rear wheels not covered at the top by fenders, bodies, or other parts of the vehicle shall be covered at the top by protective means extending at least to the center line of the rearmost axle.

Section 5577.12 | Liability for damages - prosecution - application of moneys.
 

Any person violating any law relating to or regulating the use of the improved public roads shall be liable for all damage resulting to any such street, highway, bridge, or culvert by reason of such violation. In case of any injury to such a street, highway, bridge, or culvert, such damages shall be collected by civil action, brought in the name of the state, on the relation of the director of transportation with respect to highways under his jurisdiction, and the attorney general or prosecuting attorney of any county shall institute such action, when requested by the director and prosecute it to final judgment. In case of any injury to an improved public road, bridge, or culvert of a county, by reason of the violations of any of the rules or regulations made by the board of county commissioners, the damages shall be recovered by a civil action prosecuted by the board; in case of an injury to an improved public street, highway, bridge, or culvert of a municipal corporation, it shall be the duty of the proper authorities of such municipal corporation to institute an action for the recovery of such damages; and in the case of an injury to an improved public street, road, bridge, or culvert of a township, the damages shall be recovered by a civil action prosecuted by the board of township trustees.

The board of county commissioners shall appropriate such amount of money annually, from the road fund of the county, as is necessary to equip and compensate such deputy. The patrolmen of the county highways may be deputized by the sheriffs of the counties in which they are employed, as deputy sheriffs, but shall receive no extra compensation.

Section 5577.14 | Notice of arrest.
