What should a driver understand from this Curve Right sign?
-
A.
Slow before the rightward curve and keep to your lane. Correct
-
B.
Stop at the curve and yield to oncoming traffic before entering.
-
C.
Make a sharp right turn at the intersection ahead.
-
D.
Merge left because the right lane ends ahead.
The answer is "Slow before the rightward curve and keep to your lane."
This is a warning of a rightward curve, so be ready to slow before the bend as the road calls for and hold your lane through it. Drivers who read a yellow warning diamond as though it carried the regulatory force of a red-and-white sign, expecting it to command a stop or yield, are the ones drawn to the stop-and-yield answer.
The traps in the wrong answers
B. Stop at the curve and yield to oncoming traffic before entering.
A yellow warning diamond advises a speed adjustment before the curve; it does not command a stop or a yield to oncoming traffic. This answer reads the yellow warning diamond as though it carried the regulatory force of a red-and-white sign, commanding a stop or a yield at the curve.
C. Make a sharp right turn at the intersection ahead.
The rounded arrow shows a gentle bend in the roadway itself, not the right-angle corner of an intersection turn. This answer confuses the smooth curved arrow of W1-2R with the right-angle arrow of the W1-1R Turn sign, which warns of a much tighter bend.
D. Merge left because the right lane ends ahead.
This sign shows a curving road, not a tapering lane line, so no merge is called for here. This answer treats a bend drawn into the roadway itself as though it were the tapering lane-line diagram used on lane-reduction warnings.
