Escorts

When escorts are needed and # of vehicles required

  • Width from 12′ up to 16′ requires 1 escort (Front on 2-lane highway, Rear on 4-lane or more highway)
  • Width from 16’1″ to 18′ requires 1 State Trooper* (on 2-lane & 4-lane Highways or more lane highways)
  • Width exceeds 18′ requires 2 State Troopers (on 2-lane & 4-lane Highways or more lane highways)
  • Length from 90′ up to 125′ requires 1 escort (Rear) on all highways
  • Height over 15’10” requires a height pole off interstate

* While Louisiana requires one escort, 2 may be recommended in some places

Super loads

  • When the gross vehicle weight exceeds 254,000 pounds, permit requests require detailed information and inquiries should be directed to the Truck Permit Office well in advance of the movement (generally one month).
  • Loads exceeding 900,000 pounds may require analysis from an independent engineering firm and additional time should be allowed for this analysis.

Escort vehicle requirements can differ significantly by state in terms of mandatory driver qualifications, training, certifications, vehicle weights, obligatory signage/flags/lighting, necessary onboard equipment, and more. The ODS team can provide you with all additional requirements specific to your route.

Operating Times

In general, vehicles and loads requiring a permit are prohibited from traveling in inclement weather and on certain designated holidays. Travel is permitted daylight hours only, unless time restrictions apply.

Vehicles with loads in excess of 12’ wide may not cross the Jimmy Davis Bridge (LA 511) between 7:00am. to 9:00am. and 3:30pm. to 5:30pm

Vehicles requiring permits may not cross any bridge spanning the Mississippi River or be within 2 miles of such bridge from 6:30am. to 9:00am. and 3:30pm. to 6:00pm., Monday through Friday. This restriction applies only in New Orleans.

Vehicles with loads in excess of 12’ wide may not travel in the city of New Orleans between 7:00am. to 9:00am and 3:30pm to 6:00pm, Monday through Friday. This restriction does not apply to movement on the Interstate System or that section of US-90 Business between the Crescent City Connection Bridge and Interstate 10.

No vehicle whose load projects beyond the boundaries of the vehicle, or whose width exceeds 8’ 6”, height exceeds 14’ 4”, length exceeds 70’ 0” or the weight exceeds 120,000 lbs. will be allowed to cross the US-190 Mississippi River Bridge in Baton Rouge from 6:30am. to 9:00am. and 3:30pm. to 6:00pm. Monday through Friday.

Night movement is allowed on a case by case basis and is not limited to a certain dimension. Per Louisiana’s Revised Statue 32:387, “If a permit issued pursuant to Subsection B of this Section authorizes a vehicle to operate on interstate highways, the secretary may allow the vehicle to operate on interstate highways at night if requested by the owner or operator”. Also, Louisiana does allow night movement off of the interstate system if there is a need (traffic issues, safety issues, some type of emergency, etc.). If nighttime movement is allowed, it is stated on the permit along with the requirements.

Holidays

Oversize and overweight vehicle movement, with the exception of permit loads that qualify for 24-hour movement, will be prohibited on all State highways in selected areas on Saturday, February 22, 2020, through Tuesday, February 25, 2020, in observance of the Mardi Gras season. The selected areas are:

  1. Parishes of Orleans, Jefferson and St. Bernard (including the interstates)
  2. Within the city limits of Lafayette, with the exception of I-10
  3. Within the city limits and surrounding area of New Roads
  4. Within the city limits and surrounding area of Houma
  5. Within the city limits and surrounding area of Lake Charles, with the exception of I-10 and I-210

No oversize/overweight movement is permitted from sunrise to sunset on New Year’s Day, Thanksgiving Day, and Christmas Day.

Adverse weather

Vehicles and loads requiring a permit are prohibited from traveling during weather that is physically severe such as extremely heavy rain, heavy fog, icy road conditions, heavy snow, or any continuous condition which creates low visibility for drivers or hazardous driving conditions. Wet pavement, light drizzle or wind is not considered inclement weather for the purposes of permit movement.

Permit movements are not prohibited from traveling in these milder weather conditions unless the movement would create a traffic hazard; for example, movement of a load 14’ wide during rain or movement of mobile homes in wind.
