A plate under a STOP sign reads ALL-WAY. What does the plate tell drivers approaching the intersection?
-
A.
Drivers may treat the sign as a YIELD when clear.
-
B.
Every approach to the intersection has a STOP sign. Correct
-
C.
The intersection is monitored by a traffic camera.
-
D.
Only trucks and buses must come to a full stop.
The answer is "Every approach to the intersection has a STOP sign."
An ALL-WAY plate under a STOP sign means every approach to the intersection has a STOP sign, so cross traffic must also stop. Choice A is the trap: 'all-way' sounds looser, as if the shared stopping loosens the rule for the last driver up; the plate adds STOP signs, it does not weaken them.
The traps in the wrong answers
A. Drivers may treat the sign as a YIELD when clear.
The ALL-WAY plate adds STOP signs on other approaches; it does not weaken any of them. This answer reads 'all-way' as looser because everyone stops, easing the rule for the last driver up.
C. The intersection is monitored by a traffic camera.
Camera enforcement uses a separate sign, not the ALL-WAY plate. This answer confuses the plate with red-light camera warning signage.
D. Only trucks and buses must come to a full stop.
The plate applies to every driver on every approach. This answer applies railroad-crossing bus and truck stop rules to a four-way stop.
