Okla. Stat. tit. 47, § 47-14-113: When the department of highways or local authorities

may restrict right to use highways.

The Director of the Department of Transportation with respect to

highways on the state highway system, or local authorities with

respect to highways under their jurisdiction, as defined in Title 69

of the Oklahoma Statutes, may prohibit the operation of vehicles on

any such highways, or impose restrictions as to the weights of

vehicles to be operated upon any state or federal highway or any

detour established for such highways, or for any bridge located upon

such highways or detours, whenever any such highway, detour or

bridge by reason of deterioration, rain, snow or other climatic

conditions will be seriously damaged or destroyed unless the use of

vehicles thereon is prohibited or the permissible weight reduced.

Such restrictions shall be effective when signs giving notice

thereof are erected upon the highway, detour, bridge, or portion

thereof affected by such action, and the Department of Public Safety

has been notified. The purpose of this provision with respect to

local authorities is to give such authorities an opportunity to

prevent or minimize an immediate threat of serious harm or

destruction to any highway, detour or bridge under their

jurisdiction due to rain, snow or other climatic conditions.

Nothing stated herein shall be construed to grant local authorities

the right to issue permits designed to regulate the use of

overweight vehicles upon highways subject to their jurisdiction, and

the issuance of such permits is expressly prohibited.
