When pilot cars are required.
Pilot Car and Escort vehicle information:

Width: If shipment is over 14′ in width you will be required to have 1 front and 1 rear pilot car (escort).
Height: All depends on proposed routing. If height of load exceeds 15′ you will “probably” be required to have a front high pole escort but not positively. If height is 17′ you will more than likely be required to have a high pole escort in the front of the load. Call and speak with them directly for clarification.
Weight: Check with the Utah port of to see if your weight class will require a pilot car/escort.
Overhang: No specified limits. This is something they like to see for themselves at the ports. If your load is secure and safe looking but not too long overall and have flags/amber lights then you will possibly not be required to have a pilot car.
