Raw logs

A pole trailer or semitrailer combination hauling raw logs:

• May not exceed 75 feet in overall length.
• The semitrailer combination does not require a permit unless greater than 75 feet in length. If over 75 feet, a trip permit is required.
• Is allowed an overhang of not more than 15 feet for any log. The overhang is measured from the center of rear axle. Except by special single-trip permit.

Length means total length of the vehicle combination from the front bumper to the most distant end of the logs hauled. These provisions do not apply to a vehicle combination hauling utility poles.
