  • Front and rear escorts must travel with vehicles which exceed 14’ in width up to and including 16’ wide.
  • No specific requirements exist for overlength or overheight vehicles.

Super loads:

Super loads are those exceeding 130,000 lbs., 125' long (including overhang), or 16' wide. Super load permits are also required for loads limited by overhead structures (must clear by 3”) or those with front overhangs of 3’ and rear 15’ on trailers less than 48’ long and 10’ on trailers between 48’ and 53’ long (5’ rear overhang on loads only on 40’ straight trucks).

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.
