You are driving on the terminating highway of a T intersection with no signs or lights. What must you do?
-
A.
Come to a stop only if another vehicle is turning
-
B.
Yield to cross traffic before entering Correct
-
C.
Proceed first because you have priority on the through road
-
D.
Sound your horn once and continue
The answer is "Yield to cross traffic before entering"
On the terminating highway of a T intersection with no signs or lights, you yield to cross traffic before entering. Choice C snags drivers who treat straight-through movement as automatic priority, a habit built up on through roads where cross traffic is the one that stops.
The traps in the wrong answers
A. Come to a stop only if another vehicle is turning
The yield applies regardless of what the cross traffic is doing; whether they turn or continue straight does not change the rule. This answer narrows the yield to a subset of situations, borrowing the yield-only-if-crossing habit from four-way stop logic.
C. Proceed first because you have priority on the through road
You are on the terminating highway here, not the through road; the terminating highway is the one that yields. This answer reads any straight path as the through road, a habit built on T intersections where signs give priority to the continuing route.
D. Sound your horn once and continue
A horn does not create right of way at an intersection; the rule requires yielding, not signaling your presence. This answer treats a horn as a substitute for yielding, an idea that shows up in bad-habit driving but is not in any right-of-way rule.
