1. When operating along a route that is 8 miles or less in width- 4 miles.
2. When operating along any route segment that is greater than 8 miles in width - 9 miles, except that 15 miles must be applied along that portion of any route segment requiring extended usable distance limitation beyond 130 miles of the reference facility.
