What does this Merge Right sign warn of ahead?
-
A.
Traffic from the right merges into your lane ahead. Correct
-
B.
A lane on the right ends and drivers must move left.
-
C.
The roadway narrows from both sides ahead.
-
D.
Two-way traffic begins on the roadway ahead.
The answer is "Traffic from the right merges into your lane ahead."
The diamond warns that traffic from the right merges into your lane ahead, which is why you check your right mirror and blind spot as you approach and adjust speed for vehicles joining. The trap is the answer about a lane ending and drivers moving left; that is the Lane Ends sign, and readers pick it because both signs feature a slanting line and get filed together on first pass.
The traps in the wrong answers
B. A lane on the right ends and drivers must move left.
That description belongs to the Lane Ends sign, which warns your own lane runs out ahead. This answer treats the slanted line as a right lane ending instead of a right-side lane joining yours.
C. The roadway narrows from both sides ahead.
A Narrow Road warning shows both edges pinching in; this device angles from the right only. This answer mistakes a single joining edge for the symmetric pinch that a road-narrows warning depicts.
D. Two-way traffic begins on the roadway ahead.
A Two-Way Traffic warning shows two opposing arrows; this sign shows one lane joining in the same direction. This answer reads the joining arrow as opposing-direction traffic beginning rather than same-direction traffic entering.
