At an intersection marked ALL-WAY STOP, who proceeds first?
-
A.
The driver in the largest vehicle.
-
B.
The driver on the widest road.
-
C.
The driver who reaches the stop first. Correct
-
D.
The driver going straight ahead.
The answer is "The driver who reaches the stop first."
At an all-way stop the first driver to stop is the first driver to go. Choice D is the trap, borrowing the straight-has-priority rule from unprotected left turns; the priority rule at a four-way stop is arrival order, not direction of travel.
The traps in the wrong answers
A. The driver in the largest vehicle.
Vehicle size gives no priority under Illinois right-of-way rules at an all-way stop. This answer applies a courtesy habit of yielding to trucks as if it were a written rule.
B. The driver on the widest road.
Road width is not the tiebreaker at an all-way stop; arrival order is. This answer reaches for a road-hierarchy instinct that governs neither this intersection nor the manual's rule.
D. The driver going straight ahead.
Direction of travel matters on unprotected left turns, not in the arrival order at an all-way stop. This answer carries the through-traffic priority for turns into a four-way stop where it does not apply.
