Guidelines For Establishing Truck Lane Restrictions On Eligible

HIGHWAYS. (1) Interstate highways and other access controlled, multilane divided highways that have three (3) or more through lanes in each direction of travel are eligible for truck lane restrictions. (2) Only those portions of eligible highways approved by the Department of Transportation and where appropriate signage has been installed shall be considered as having truck lane restrictions. (3) Truck lane restrictions shall terminate within two (2) miles of a left lane exit to allow ample time for lane transitions. (4) Existing truck lane restrictions may be temporarily terminated or modified during highway construction and other special events at the discretion of the Department of Transportation. (5) Truck lane restrictions should be avoided in areas where the average truck spacing is less than 500 feet per lane. (6) Signs shall be placed in accordance with the Manual on Uniform Traffic Control Devices (MUTCD) to provide motorists with notification of the restricted zone. Examples of the signs may be found in the current edition of the Tennessee Supplement to Standard Highway Signs and the MUTCD. (7) These rules do not apply to those portions of highways where “truck climbing lanes” have been established due to excessive grades or where special truck lane restrictions have been established in construction zones. (8) The Commissioner of the Department of Transportation reserves the authority to remove or modify truck lane restriction zones established under these rules.
