What does a No Turn on Red sign require at a signalized intersection?
-
A.
Turn only after yielding to oncoming traffic.
-
B.
Wait for the signal to turn green before turning. Correct
-
C.
Stop, then turn when the intersection is clear.
-
D.
Turn only when a green arrow is displayed.
The answer is "Wait for the signal to turn green before turning."
Oregon allows turns on red after a complete stop in most cases, but a No Turn on Red sign overrides that rule for that intersection. You must wait for the signal to turn green before turning. The sign is posted where a turn on red would conflict with sight lines, pedestrian flow, or other movements.
The traps in the wrong answers
A. Turn only after yielding to oncoming traffic.
This describes a permitted turn on red, which is exactly what the sign prohibits. Misreading: Treats the intersection as a permitted-turn-on-red scenario, ignoring that the sign forbids any turn during the red light.
C. Stop, then turn when the intersection is clear.
This is the default turn-on-red rule, which the sign overrides. Misreading: Applies the general stop-then-turn-on-red rule and ignores that the No Turn on Red sign overrides it at this intersection.
D. Turn only when a green arrow is displayed.
The sign does not require a green arrow; a steady green circular signal is enough to turn. Misreading: Adds a green-arrow requirement the manual does not state; the rule only requires waiting for the signal to turn green.
