Warning Signs and Flags
"OVERSIZE LOAD": Warning signs are required on the front and back of all oversize loads. Size: 7' long, 18" high Letters Black, 10" high, 1.5" brushstroke Background: yellow
All flags shall be 18" square clean bright red flags on all four corners of the extremities of over width objects, and at the extreme ends of all protrusions, projections, or overhangs.
During reduced visibilities (inclement weather): Two (2) amber lights, visible from front and sides, must be attached at the widest points on the front. If the over width part is at or near the rear of the vehicle, this light may be red and visible from front, side and rear.
On rear overhangs more than 4', 2 red lights [1 on each side] and 2 red reflectors must be visible from the rear, must indicate maximum width of the overlength or projecting part.
If the overlength or projecting part is two (2) feet wide or less, one (1) red light and one (1) red reflector is sufficient.
Wheels and Tires - Must have at least 2/32" of tread measured in any 2 adjacent major grooves. No knots, bulges, sidewall cracks or tread exposure allowed.
Restrictions as to tire equipment
A. Every solid rubber tire on a vehicle moved on any highway of this state shall have rubber on its entire traction surface at least one inch thick above the edge of the flange of the entire periphery of the rim of the wheel.
B. No tire on a vehicle moved on a highway shall have on its periphery any protuberances of any material, other than rubber, which projects beyond the thread of the traction surface of the tire.
It is permissible to use tire chains of reasonable proportions upon any vehicle, when required for safety because of conditions tending to cause a vehicle to slide or skid.
C. The department may issue emergency permission authorizing the operation upon the highways of traction engines or tractors having movable tracks with transverse corrugations upon their periphery, or farm tractors or other farm machinery or instruments of husbandry.Note onTire Width: There’s no legal restriction on the width of the truck tires themselves, but they’re not allowed to extend beyond the fenders of the truck in virtually every state. One simple and perfectly legal way around this is to put fender flares on the truck that are wider than the truck tires. These are counted as part of the fender, so extremely wide tires are legitimate as long as they don’t stick out beyond the fenders.
Maximum Dimensions "The Envelope":
Loads with dimensions exceeding the envelope vehicle must obtain a separate oversize/overweight trip permit. Vehicles using this permit are prohibited from crossing bridges with a posted weight limit and from travel in restricted construction zones.
Vertical clearances will be the responsibility of the permittee.
Permits expire one year from the beginning movement date. The permit will be issued for the pulling unit and is non-transferable and non-refundable. Loads with a gross vehicle weight exceeding 108,000 pounds are required to have a truck/trailer combination of at least six (6) axles.
Vehicles with a valid permit are not prohibited from traveling at night, during moderate rain, or on holidays if the width and length are legal.
The agreement, application, and power of attorney form are available from the Truck Permit Office. Annual Overweight Permits are computer generated forms, and are embossed with a state seal. The original embossed permit must be carried in the vehicle for which it was issued. They may be obtained only from the Truck Permit Office.
These permits do not allow additional length for specialized hauling equipment (i.e. car haulers, boat haulers, dromedary units). The legal length of these types of equipment is 75 feet non-inclusive of a 3 foot front overhang and a 4 foot rear overhang.

These permits are for vehicles and loads which exceed the legal limitation on length, width, height, or projecting loads.
Exception: Overlength-only vehicle combinations, but not mobile homes, that haul loads of the same product all day may make more than one (1) trip per day. However, any change in destination or origin of the vehicle or load would require an additional $10.00 permit.

Exception: Mobile Homes that are oversize but not overweight will be issued an Oversize Permit for a consecutive seventy-two (72) hour permit with no extensions.
Note: Oversize equipment that is being used to move an oversize load may use a single Oversize Permit to travel to the point where the commodity is picked up, travel to the load’s destination, and return to the point of origin when empty as long as the entire trip is on the same day and all the highways being used are shown on the permit. These permits are computer generated forms from the Truck Permit Office or by Web application.
1. A mobile home being moved from a point of origin in Louisiana or any other point, whether in Louisiana or out-of-state, must have a valid Louisiana registration certificate.
2. Mobile homes traveling to or through Louisiana are exempt from Louisiana registration if they are properly registered in their home state.
