Off-Interstate Business Loop marker sign

What to do

Follow it to reach the town's business district.

Follow the green shield to reach the town centre and, for a LOOP, to rejoin the same Interstate further on.

Where it's used

Section 2D.11 requires the Off-Interstate Business Route sign to be a cut-out shield of the same shape and size as the Interstate Route sign, with white legend and border on green, showing the connecting Interstate's number and the words BUSINESS and LOOP (M1-2) or SPUR (M1-3). LOOP is used when the route rejoins the same Interstate, SPUR when it leaves and does not rejoin, and the word INTERSTATE may never appear on it. It may be used on a major non-Interstate highway that serves a city's business area from an Interstate interchange.

Don't confuse it with

• Interstate Route marker: The Interstate marker is red, white and blue and marks the Interstate itself, while the green Business Loop marker leads off it through town.
• U.S. Route marker: The U.S. Route marker is a black-and-white shield for a U.S. highway, not a business route.
