You are waiting to turn left at an intersection with no signs, signals, or police present. Oncoming vehicles are heading straight through. What does the manual require?
-
A.
Proceed together with the oncoming driver, sharing the lane.
-
B.
Take the turn if you arrived at the intersection first.
-
C.
Proceed first because left-turning traffic has priority.
-
D.
Yield to the oncoming vehicles before turning. Correct
The answer is "Yield to the oncoming vehicles before turning."
Rule 2 in the Negotiating Intersections list states that drivers turning left must yield to oncoming vehicles going straight ahead. Choice C tempts drivers picturing a green-arrow phase; the arrow (not the left turn itself) is what grants priority, and without that arrow the left-turning driver always yields.
The traps in the wrong answers
A. Proceed together with the oncoming driver, sharing the lane.
The manual does not allow opposing through and left-turning traffic to share a lane; you must wait for a safe gap in oncoming traffic. This answer borrows the four-way-stop allowance that facing drivers may both proceed with caution and stretches it to opposing through traffic outside a four-way stop.
B. Take the turn if you arrived at the intersection first.
Order of arrival does not resolve a left turn against oncoming traffic; the left-turning driver yields regardless of who arrived first. This answer applies the four-way-stop rule that the first vehicle to reach the intersection should move forward first to a left-turn conflict where it does not apply.
C. Proceed first because left-turning traffic has priority.
Reverses the yield rule; the manual assigns the yield duty to the left-turning driver, not to oncoming through traffic. This answer generalizes from a protected green-arrow phase and treats left-turn priority as the default rule at every intersection.
