Oversized Guidelines

Policy on the Movement of Oversized Loads

Policy on the Movement of Oversized LoadsThe following guidelines indicate the maximum vehicle and/or payload size allowable and when prior approval is required. Please note that during inclement weather (i.e.: high winds, snowy/icy conditions, etc.) travel with double- and triple-bottom trailers is discouraged.

TRACTOR-TRAILER COMBINATIONS
The Kansas Turnpike presently allows single, tandem and triple trailer combinations to operate day or night.

LENGTH RESTRICTIONS
Any vehicle, or combination of vehicles, trailer(s), or load exceeding 125 feet in overall length must obtain authorization from a Chief Engineer, the Turnpike Highway Patrol Commander, or his designee, prior to moving such vehicle on the Kansas Turnpike. Authorization will not be granted for night operation, except in extreme emergency, or disaster conditions.

HEIGHT RESTRICTIONS
Vehicles and/or loads activating high load detectors when entering the Kansas Turnpike are required to stop, and cannot proceed until authorized by a Turnpike Highway Patrol Trooper. All overhead structures on the Kansas Turnpike will allow movement of loads not exceeding 14 feet in height. All vehicles and/or loads over 14 feet in height will be denied entry until a Turnpike Highway Patrol Trooper has measured the load. The trooper will then authorize or prohibit entry onto the Kansas Turnpike based on the measured height of the vehicle and/or load and the destination of the vehicle and/or load.

WIDTH RESTRICTIONS
Vehicles and/or loads up to, but not exceeding 12 feet in width may use the Kansas Turnpike without special authorization during daylight hours. Loads exceeding 8 feet 6 inches in width MAY NOT travel the Kansas Turnpike during nighttime hours. Authorization for loads wider than 8 feet 6 inches during nighttime operation will only be granted in extreme emergency or disaster conditions. Vehicles and/or loads exceeding 12 feet wide are required to obtain authorization from a Chief Engineer, the Turnpike Highway Patrol Commander, or his designee prior to using the Kansas Turnpike. Movement of vehicles over 14 feet in width is limited to Monday through Thursday between the hours of 8:30 a.m. to 4:30 p.m. At least one escort vehicle is required to accompany the movement of loads over 14 feet in width on the Kansas Turnpike. Vehicles and/or loads exceeding 16 feet in width will rarely be authorized for any operation on the Kansas Turnpike.

SEE CURRENT WIDTH RESTRICTIONS

MOBILE HOMES
Mobile homes up to and including 12 feet in width may be moved only during daylight hours, with prior approval (see Width Restrictions).

The movement of mobile homes over 14 feet in width will be limited to Monday through Thursday, between the hours of 8:30 a.m. and 4:30 p.m. Additionally, the movement of any such mobile homes on the Kansas Turnpike must be concluded by noon on any day preceding a legal holiday. At least one escort vehicle is required to accompany the movement of each mobile home over 14 feet in width on the Kansas Turnpike.

Overall length will be allowed up to and including 125 feet.

All mobile homes must be towed by a truck-tractor specifically designed and equipped to tow mobile homes. Towing of more than one mobile home at any one time by a single power unit, will not be permitted.

All movement of mobile homes must comply with the Kansas Department of Transportation Rules and Regulations regarding flags, lights, signing and insurance requirements.

OTHER INFORMATION
Special permits from the Kansas Department of Transportation are not required to move oversize loads on the Kansas Turnpike. Movement of any oversize loads, however, must comply with Kansas laws governing authority, insurance, lights, flags, signs, placards and safety equipment. It is the responsibility of the driver of any oversize vehicle and/or load entering or exiting the Kansas Turnpike to determine if the toll plaza has adequate space for the safe entry or exiting of the vehicle and/or load. Daylight hours are those hours between sunrise and sunset.

For more information or questions about oversize vehicles, please call Kansas Turnpike/KHP Troop G at (316) 682-4537 ext. 2202.
