Miss. Code § 27-5-73
The Mississippi Department of Transportation is hereby authorized and directed to establish and maintain inspection stations adjacent to or near such highways as it may deem necessary and desirable, and at such locations as it may deem necessary. At least forty (40) of the inspection stations, when established, shall be kept open twenty-four (24) hours per day, seven (7) days per week, unless the transportation department determines that adequate enforcement can be maintained by reducing the number of hours that a particular inspection station should remain open. Such inspection stations may be established upon existing rights-of-way or upon additional rights-of-way if it be deemed necessary by the transportation department to acquire such rights-of-way. Necessary driveways shall be constructed across such rights-of-way to the inspection stations and, if necessary, drive-out spaces on the opposite side of the highway from the inspection stations. All inspection stations shall be so located and all drive-outs established and maintained in such a manner that it shall not be necessary for any vehicle to stop with any portion of the vehicle on or within five (5) feet of the paved or traveled portion of the highway. When any inspection station is required to be constructed or reconstructed, the transportation department shall construct the inspection station area with its own forces or by contract.
