Ohio Code § 5577.07

§ 5577.07.

When thaws or excessive moisture render the improved highways of this state or any

sections of them insufficient to bear the traffic thereon, or when such highways would

be damaged or destroyed by heavy traffic during the period of thawing or excessive

moisture, the maximum weight of vehicle and load, or the maximum speed, or both, for

motor vehicles, as prescribed by law shall be reduced in the following manner: (A) On state highways, the director of transportation shall prescribe such reduction

which shall not be more than twenty-five per cent; (B) On improved highways and all other roads in the county, other than state highways,

the board of county commissioners shall prescribe such reduction as the condition

of the road or highway justifies, but in no case shall the reduction be more than

fifty per cent. The schedule of the reduction of maximum weights and speeds shall be filed, for the

information of the public, in the office of the board of each county in which the

schedule is operative and in the office of the director.  The director or board, at least one day before such reduction becomes effective,

shall cause to be placed and retained on such highways, at both ends and at the points

of intersections by principal roads, during the period of such reduced limitation

of weight, speed, or both, signs, of substantial construction, which will conspicuously

indicate the limitations of weight and speed, which are allowed on the highway and

the date on which such limitations shall go into effect.  No person shall operate upon any such highway, a motor vehicle whose maximum weight

or speed is in excess of the limitations prescribed.  The expense of the purchase and erection of signs, provided for in this section,

shall be paid from funds for the maintenance and repair of roads.
