The number printed on a green exit sign helps a driver:
-
A.
Identify which exit to take. Correct
-
B.
Know the speed limit on the ramp.
-
C.
See how far it is to the next city.
-
D.
Find which route number they are on.
The answer is "Identify which exit to take."
The exit number on a green guide sign tells you which exit to take. Speeds, mileage, and route numbers each get their own sign type. Read the exit number as a label for the exit, not as anything else.
The traps in the wrong answers
B. Know the speed limit on the ramp.
Ramp speeds appear on yellow advisory speed signs, not on exit number plaques. Misreading: Confuses the exit number on a green guide sign with the yellow advisory speed sign that posts safe speeds for freeway ramps and curves.
C. See how far it is to the next city.
Distances to cities are shown on separate green mileage signs. Misreading: Treats the exit number as a distance figure, ignoring that the manual ties the number on an exit sign to identifying which exit to take.
D. Find which route number they are on.
Route numbers appear on shield-shaped route markers, not on exit number signs. Misreading: Conflates exit numbers with route signs, which the manual lists separately as showing which interstate, U.S. route, or state highway you are on.
