Stat. tit. 47, § 47-11-801","heading":"Basic rule - Maximum and minimum limits – Fines and","body":"penalties.\n\nA. Any person driving a vehicle on a highway shall drive at a\n\ncareful and prudent speed not greater than nor less than is\n\nreasonable and proper, having due regard to the traffic, surface,\n\nand width of the highway and any other conditions then existing. No\n\nperson shall drive any vehicle upon a highway at a speed greater\n\nthan will permit the driver to bring it to a stop within the assured\n\nclear distance ahead.\n\nB. Except when a special hazard exists that requires lower\n\nspeed for compliance with subsection A of this section, the limits\n\nspecified by law or established as hereinafter authorized shall be\n\nmaximum lawful speeds, and no person shall drive a vehicle at a\n\nspeed in excess of the following maximum limits:\n\n1. On a highway, part of a highway, or on roads located on\n\nlands owned by a state beneficiary public trust, unless otherwise\n\nestablished in law, a speed established by the Department of\n\nTransportation on the basis of engineering and traffic\n\ninvestigations used to determine the speed that is reasonable and\n\nsafe under the conditions found to exist on the highway, part of the\n\nhighway, or road;\n\n2. For a school bus, fifty-five (55) miles per hour on paved\n\ntwo-lane roads except on the state highway system, the interstate\n\nhighway system, and the turnpike system where the maximum shall be\n\nsixty-five (65) miles per hour;\n\n3. On any highway outside of a municipality in a properly\n\nmarked school zone, twenty-five (25) miles per hour, during certain\n\ntimes as provided in Section 11-806.1 of this title and provided the\n\nzone is marked with appropriate warning signs placed in accordance\n\nwith the latest edition of the Manual on Uniform Traffic Control\n\nDevices for Streets and Highways. The Department of Transportation\n\nmay determine on the basis of an engineering and traffic\n\ninvestigation that a speed limit higher than twenty-five (25) miles\n\nper hour may be reasonable and safe under conditions as they exist\n\nupon a highway, and post an alternative school zone speed limit.\n\nThe Department shall mark such school zones, or entrances and exits\n\nonto highways by buses or students, so that the maximum speed\n\nprovided by this paragraph shall be established therein. Exits and\n\nentrances to controlled-access highways which are within such school\n\nzones shall be marked in the same manner as other highways. The\n\ncounty commissioners shall mark such school zones along the county\n\nroads so that the maximum speed provided by this paragraph shall be\n\nestablished therein. The signs may be either permanent or\n\ntemporary. The Department shall give priority over all other\n\nsigning projects to the foregoing duty to mark school zones. The\n\nDepartment shall also provide other safety devices for school zones\n\nwhich are needed in the opinion of the Department;\n\n4. Twenty-five (25) miles per hour or a posted alternative\n\nschool zone speed limit through state schools located on the state-\n\nowned land adjoining or outside the limits of a corporate city or\n\ntown where a state educational institution is established;\n\n5.

The Transportation Commission is hereby authorized to\n\nprescribe maximum and minimum speeds for all vehicles and any\n\ncombinations of vehicles using controlled-access highways.

The Transportation Commission is hereby authorized to\n\nprescribe maximum and minimum speeds for all vehicles and any\n\ncombinations of vehicles using controlled-access highways. Such\n\nregulations shall become effective after signs have been posted on\n\nthese highways giving notice thereof. Such regulations may apply to\n\nan entirely controlled-access highway or to selected sections\n\nthereof as may be designated by the Transportation Commission. A\n\nspeed limit of seventy-five (75) miles per hour may be set in\n\nlocations comprising rural segments of the interstate highway system\n\nby the Transportation Commission; provided, however, that speed is\n\ndetermined to be safe and reasonable after a traffic or engineering\n\nstudy has been completed by the Department.
