	of the highway. 

(3)	The speed limit for motor vehicles on state highways shall be as follows, unless 
	conditions exist that require lower speed for compliance with subsection (2) of this 
	section, or the secretary of the Transportation Cabinet establishes a different speed 
	limit in accordance with subsection (4) of this section:

	(b) Fifty-five (55) miles per hour on all other state highways; and 
	(c) Thirty-five (35) miles per hour in a business or residential district. 
(4)	(a)	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, 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 subsection (3) of 
		this section in excess of sixty-five (65) miles per hour, except that, 
		notwithstanding the provisions of subsection (3)(a) of this section, the 
		secretary may increase the speed limit on any of the following segments of

		established speed limits without an engineering or traffic investigation. A 
		speed limit established under this paragraph shall become effective when and

		Nothing in this paragraph shall be construed to prevent the Transportation 
		Cabinet from using moveable or portable speed limit signs in highway work

		jurisdiction, except as provided in paragraph (b) of this subsection. 
	(b)	The alteration of speed limits on state highways within a city or a county shall

		increase any speed limit established by subsection (3)(b) or (c) of this section 
		in excess of fifty-five (55) miles per hour. 
	(c)	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 (1) 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. 
(6)	The speed limit for motor vehicles in an off-street parking facility offered for public 
	use, whether publicly or privately owned, shall be fifteen (15) miles per hour. 
(7)	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. 
(8)	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.
