US Road Signs Warning Signs

What does this warning sign tell a driver to expect on the road ahead?

Diamond-shaped yellow-green panel with black border showing a bicycle silhouette above a walking pedestrian.
  1. A.
    A shared crossing used by pedestrians and bicyclists Correct
  2. B.
    A school crosswalk where children cross the road
  3. C.
    A bike lane beginning along the roadway
  4. D.
    A pedestrian-only crosswalk with no bikes
The Why

The answer is "A shared crossing used by pedestrians and bicyclists"

The W11-15 warns of a shared crossing where pedestrians and bicyclists may enter the roadway, usually where a sidepath or multi-use trail meets the road at one point. The school-crosswalk reading is the trap because the S1-1 school crossing sign carries the same fluorescent yellow-green background, so the color reads to some drivers as 'children crossing' when it actually flags any non-motorist crossing.

Why the others miss

The traps in the wrong answers

B. A school crosswalk where children cross the road

The fluorescent yellow-green background flags any non-motorist crossing, not children in particular. This answer reads the yellow-green diamond as the S1-1 school crossing sign because that device uses the same fluorescent color.

C. A bike lane beginning along the roadway

A warning diamond flags a crossing point, not the start of a lane, and this device covers riders and walkers together. This answer treats the bicycle symbol as a bike-lane starter marker instead of a warning that riders may enter.

D. A pedestrian-only crosswalk with no bikes

The sign warns of bicyclists alongside pedestrians, so a walker-only reading misses half of what it flags. This answer drops the bicyclist half of the warning and treats the device as an ordinary pedestrian crosswalk sign.
