  3. C
    It warns drivers that the upcoming main Interstate section requires a mandatory toll for non-resident vehicles.
  4. D
    It identifies an emergency bypass route designed to detour long-distance traffic entirely around the metropolitan area.

Answer

It designates a highway route that branches off the main Interstate to traverse the city's commercial district before reconnecting to the highway.
Interstate Business Loop and Spur signs are green rectangular or shield-shaped guide signs that inform motorists of a designated route leading from the primary Interstate highway directly into the main business district of a city or town and returning to the highway.

Step-by-Step Solution

1
Identify the type and color scheme of the route marker.
The sign is an Interstate shield with a green background and white lettering, featuring the word 'BUSINESS'.
Standard Interstate route markers use a red, white, and blue design, whereas Business Loop/Spur Interstate markers use a green background to signify informational business guidance.
2
Interpret the navigational purpose of a Business route marker.
A Business Loop or Business Spur leaves the main highway, passes through the downtown or commercial center of a city, and typically rejoins the main Interstate.
Guide signs with green backgrounds provide directional guidance, location information, and route navigation to points of interest.
