Unprotected roadway lighting poles located inside the clear zone should be breakaway, unless conditions dictate otherwise.

Breakaway poles placed on the house side of freeways should be 15 feet from lane edge and should provide a clearance behind the pole of 2/5 of the mounting height. For highways other than interstates, breakaway poles placed on the house side of travel lanes should be 15 feet from lane edge where practical. If sufficient right-of-way does not exist for this clearance, the poles may be placed just inside the right-of-way line, but not closer than 2.5 feet from lane edge.
