- Over 12 feet wide and up to 16 feet wide on a multi-lane highway; or
- Over 90 feet long and up to 125 feet long.
An escort vehicle may escort two overlength vehicles or loads, but only one overwidth vehicle or load.

Headlights and rear lights on the escort vehicle and the vehicle being escorted must be lit at all times during the movement.
Pole or bucket truck escorts are required as follows:
Load Type | Pole/Bucket Truck Details |
---|---|
Loads over 15 feet 10 inches in height | A pole truck with a height indicator is required. The pole truck is to travel in
front of the permitted load to detect low clearances while traveling on the state maintained
highway system. This restriction does not preclude the requirement for bucket trucks at greater heights or as determined by the Truck Permit Office. Loads traveling strictly on Interstate highways or off the state maintained highway system will are exempt from this requirement. Loads that require an escort and are traveling on multi-lane highways will require both an escort and a pole truck (or car), since the escort vehicle is required to travel behind the loads on these highways |
Loads over 16 feet 8 inches in height | A pole truck with an approved instrument to safely lift utility
lines for the load to pass under is required. The pole truck is to travel in front of the permitted load to
safely lift utility lines while traveling on the state maintained highway system.
This restriction does not preclude the requirement for bucket trucks at greater heights or as determined by the Truck Permit Office. Loads that require an escort and are traveling on multi-lane highways will require both an escort and a pole truck (or car), since the escort vehicle is required to travel behind the loads on these highways. |
Loads exceeding 17 feet 11 inches in height | A bucket truck is required. A bucket truck could be required by the Truck Permit Office at lower heights if the movement of the load requires travel through a metropolitan area or a rural area where the number of utility lines would hinder the safe movement of the load. |
Police escorts

State police escorts are required for all vehicles and loads over:
- 16 feet wide on two-lane highways;
- 16 feet wide on multilane highways; or
