In general, the maximum allowable axle weights by special permit are:
However, a special permit for the movement of a non-divisible load may be issued for axle weights exceeding the maximum axle weights established above, subject to the following conditions:
Any movements with a gross weight exceeding 165,000 lb. may only be permitted if the movement is not detrimental or unsafe to the traveling public and the highway can accommodate the movement. In addition, such movements must be approved by the TDOT Structures Division before a special permit may be issued. Some movements with a gross weight of less than 165,000 lb. may also be subject to the prior approval of the TDOT Structures Division based on the axle spacing of the vehicle carrying the load.
Movement of super heavy and/or extra-overdimensional loads may be permitted provided the highway can accommodate and the move completed safely. “Super heavy” means that the total gross weight of the vehicle and load exceeds 165,000 lb., and “extra-overdimensional” means that the width of the vehicle and load exceeds 16ft, or the height of the vehicle and load exceeds 15 ft. 6 in..
An IRP 72-Hour trip permit is required prior to entering a jurisdiction for any vehicle having a registration, but not registered or apportioned for a particular jurisdiction. This permit allows both inter or intra movement in Tennessee.
A temporary fuel use permit is available to freight motor vehicles operated over the highways of Tennessee on an occasional or infrequent basis. The permit may be issued for a period of time not to exceed seven consecutive days and is valid only for the particular vehicle for which it has been issued. The 7-Day Temporary Fuel Use Permit is required prior to entering Tennessee. In lieu of licensing under the IFTA, persons may elect to satisfy motor fuels use tax obligations on a trip-by-trip basis.
The fee for a Tennessee Trip and Fuel Use Permit is $30 per permit plus wire service fees.
Operating an overweight, un-permitted vehicle in Tennessee is a Class C misdemeanor and, upon conviction, subject to imprisonment for not greater than 30 days or to a fine of not more than $50.00.
In addition, it is illegal to move an overloaded vehicle until the load has been reduced to bring it into legal compliance, or a special permit obtained.
Each violation of restrictions on the maximum gross weight of freight motor vehicles and each violation of rules and regulations adopted for safety under that section is a Class C misdemeanor and subject to a fine of $25.00.
Court costs range between $40 and $90 or more.
Fines for overweight loads are:
WEIGHT FINE
For the first three percent over $25 + $.03 per pound
For the remainder $25 + $.05 per pound

A person may use a tire that has embedded in it wire or other material for improving traction on snow and ice during the period of October 1 through April 15 of each year. Such a tire shall be so constructed that the percentage of wire or other material in contact with the roadway does not exceed, after the first one thousand (1,000) miles of use or operation, five percent (5%) of the total tire area in contact with the roadway.
During the first one thousand miles of use or operation of any such tire, the wire or other material in contact with the roadway shall not exceed twenty percent (20%) of the total tire area in contact with the roadway.
The studded tires allowed by this subsection shall not be used at any time on a vehicle with a maximum gross weight of more than nine thousand pounds (9,000 lbs.), unless this a vehicle is a school bus or an emergency vehicle.
It is permissible to use tire chains of reasonable proportions on any vehicle when required for safety because of snow, ice, or other condition tending to cause a vehicle to skid.
