(1)	As used in this section, unless the context
requires otherwise: 
	(a)	"Business district" means the territory 
		contiguous to and including a highway 
		if, within six hundred (600) feet along 
		the highway, there are buildings in use 
		for business or industrial purposes that 
		occupy three hundred (300) feet of frontage 
		on one (1) side or three hundred (300) feet 
		collectively on both sides of the highway; 
	(b)	"Residential district" means the territory 
		contiguous to and including a highway not 
		comprising a business district if the property 
		on the highway for a distance of three hundred 
		(300) feet or more is improved with residences or 
		residences and buildings in use for business; and 
	(c)	"State highway" means a highway or street 
		maintained by the Kentucky Department of Highways. 

(2)	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. 

(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: 
	(a) Sixty-five (65) miles per hour on interstate highways and parkways; 
	(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 
		highway to seventy (70) miles per hour: 
		1. 	Interstate 24 (entire length); 
		2. 	Interstate 64 from Interstate 264 to the West Virginia state line; 
		3. 	Interstate 65 from Interstate 264 to the Tennessee state line; 
		4. 	Interstate 71 from Interstate 264 to Interstate 275; 
		5. 	Interstate 75 from the Tennessee state line to Interstate 275; 
		6. 	The Audubon Parkway (entire length); 
		7. 	The Julian M. Carroll Purchase Parkway (entire length);
		8. 	The Bert T. Combs Mountain Parkway from Interstate 64 to the 
			beginning of the Mountain Parkway Extension (KY 9009) in Wolfe 
			County; 
		9.	The Edward T. Breathitt Pennyrile Parkway (entire length); 
		10.	The Wendell H. Ford Western Kentucky Parkway (entire length); 
		11.	The Louie B. Nunn Cumberland Parkway (entire length); 
		12.	The Martha Layne Collins Bluegrass Parkway (entire length); and 
		13.	The William H. Natcher Parkway (entire length). 
	(b)	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 paragraph 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 this paragraph shall be construed to prevent the Transportation 
		Cabinet from using moveable or portable speed limit signs in highway work 
		zones. 
(5)	(a)	A city or a county may by ordinance establish speed limits within its own 
		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 
		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 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.
