(A) An operator of a vehicle upon a highway shall not drive at a greater speed than is reasonable and prudent, having regard for the traffic and for the condition and use of the highway.
(B) The speed limit for motor vehicles on state highways shall be as follows, unless conditions exist that require a lower speed limit for compliance with division (A) above, or the Secretary of the Transportation Cabinet establishes a different speed limit in accordance with division (C) of this section:
(1) Sixty-five miles per hour on interstate highways and parkways;
(2) Fifty-five miles per hour on all other state highways; and
(3) Thirty-five miles per hour in a business or residential district.
(C) (1) If the Secretary of Transportation determines, upon the basis of an engineering and traffic investigation, that any speed limit is greater or less than is reasonable or safe under the conditions found to exist at any intersection, or upon any part of a state highway within or without the corporate limits of a city, the Secretary of Transportation may establish by official order a reasonable and safe speed limit at the location. The Secretary shall not increase any speed limit established by division (B) of this section in excess of 65 miles per hour, except that, notwithstanding the provisions of division (B)(1) of this section, the Secretary may increase the speed limit to 70 miles per hour on any of the segments of highway listed in KRS 189.390(4)(a)1. through 16.
(2) In a highway work zone, the Transportation Cabinet may temporarily reduce established speed limits without an engineering or traffic investigation. A speed limit established under this subdivision shall become effective when and where posted. The Transportation Cabinet shall post signs notifying the traveling public of the temporary highway work zone maximum speed limit. Nothing in the subdivision shall be construed to prevent the Transportation Cabinet from using moveable or portable speed limit signs in highway work zones.
(D) (1) A city or county may by ordinance establish speed limits within its own jurisdiction, except as provided in division (D)(2) of this section.
(2) The alteration of speed limits on state highways within a city or a county shall not be effective until the alteration has been approved by the Secretary of Transportation. The Secretary shall not approve any alteration that could increase any speed limit established by division (B) of this section in excess of 55 miles per hour.
(3) If a county determines, upon the basis of an engineering and traffic investigation and study, that it is unsafe to park motor vehicles on or along any highway, other than a state highway, within the unincorporated areas of the county, or that in any business district the congestion of traffic justifies a reasonable limitation on the length of time any one motor vehicle is permitted to park in such district so as to reduce the congestion, the fiscal court may by ordinance establish "no parking" areas on the highway, or limit the length of time any motor vehicle may be parked in any business district.
(E) The speed limit for motor vehicles in an off-street parking facility offered for public use, whether publicly or privately owned, shall be 15 miles per hour.
(F) A person shall not drive a motor vehicle at a speed that will impede or block the normal and reasonable movement of traffic except when reduced speed is necessary for safe operation or in compliance with law.
(G) In every charge for a violation of any speed limit specified in this section, the warrant or citation shall specify the speed at which the defendant is alleged to have driven, and the lawful speed limit applicable at the location where the violation is charged to have occurred.
