Where would you most likely see a DO NOT ENTER sign posted?
-
A.
At the start of a school zone during class.
-
B.
At the edge of a construction detour route.
-
C.
At the border of a residential parking district.
-
D.
On a one-way street or a wrong-way expressway ramp. Correct
The answer is "On a one-way street or a wrong-way expressway ramp."
DO NOT ENTER is posted on one-way streets and other roadways where you're not allowed to enter, including expressway ramps entered in the wrong direction. Choice B is the trap: construction detours are marked with the orange warning signs used in construction or maintenance zones, not the red DO NOT ENTER. Drivers who file every "you cannot go here" message under detour reach for it.
The traps in the wrong answers
A. At the start of a school zone during class.
School zones use pentagon-shaped yellow or yellow-green signs, not DO NOT ENTER. This answer confuses a school-zone entrance with a directional prohibition because both mark the edge of a zone.
B. At the edge of a construction detour route.
Construction detours are marked with the orange warning signs used in construction or maintenance zones, not the red DO NOT ENTER sign. This answer assumes any 'you cannot go here' message must belong to a construction detour.
C. At the border of a residential parking district.
Parking district limits are marked with parking-restriction signs, not DO NOT ENTER. This answer assumes any restriction on driving must be about where cars can be left.
