If more than one of the conditions above requiring only one escort are met (i.e. a load exceeding 13’ in width and 90’ in length), then two escorts are required (Front and Rear).

State police escorts

In addition to the above private escorts, a law enforcement escort is required on any vehicle or vehicle/load with an overall width in excess of 16' or any time when, in the opinion of the Department, movement may result in the high probability of delay or hazard to the traveling public or damage to highway or street facilities.

Super loads:

In Ohio, a super load is any vehicle and load combination in excess of the following:

  • WIDTH: 14’
  • HEIGHT: 14’6”
  • WEIGHT: 120,000 lbs.
  • LENGTH: Depends on routes

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.
