A flag shall be fastened to mark any extremity of size which is wider than the front or rear of the vehicle or load, whichever is wider.

Load exceeding 14' in width, two Escort vehicles, one front and one rear on two-lane, a rear Escort is required on all multi-lane highways. All loads exceeding 15'9" or more in width, two Escorts one front and one rear on all roads. When overall height is 17" or more, front Escort with height pole and a rear Escort to follow. Truck/tractor trailer combinations exceeding 80', require one Escort on two-lane roads.

Effective September 24, 2009, the following rule shall be implemented regarding requirements for vehicles and loads EXCEEDING 14 feet 6 inches in height. Every vehicle and or load EXCEEDING 14 feet 6 inches in height shall be accompanied by two escorts. One traveling in front of such load with a height pole of the same height and one following the overheight vehicle.

This is a change from requiring a height pole for vehicles and loads 15 feet 9 inches or more which did not require escorts. his emergency rule was requested, then approved by the Governor's Office during mid September 2009. The need and justification for this rule is due to the extreme amount of damage to overhead structures in the State of Oklahoma during recent years and the potential for personal injury.

Like any new rule or law, we may need to explain the reason for it to our customers. We realize this creates an additional burden on companies moving such loads. Hopefully this will save thousands of dollars in damages as well as remove some of the potential for personal injury and or death. It will take some time to educate the Industry.

Please honor all related permits issued prior to September 24, 2009 with trip dates after this effective date. It is impossible to recall all permits recently issued that required a 15' 9" height pole.

This rule will not effect the operation of an Auto Transporter which are allowed a height of 14 feet 6 inches. (Title 47, 14-103B)

If you have any questions contact the Director or a Supervisor in the Size and Weights Permit Division.

Changes reflecting this new rule will be made to our Web Site and to our Permit Restriction and Conditions list in the near future.
