|---|---|
| Group | School zone signs |
| Shape | Pentagon with a downward diagonal arrow plaque below |
| Color | Fluorescent yellow-green background, black legend and border |
What a pentagon, point up means. School zone or school crossing. Shape and color are both unique to this group.
What fluorescent yellow-green means. Pedestrian, bicycle and school warnings. Reserved so those warnings cannot be mistaken for an ordinary hazard.
School zone signs. A pentagon means school and nothing else, so the outline alone answers the question. Fluorescent yellow-green is weaker evidence, because pedestrian and bicycle signs are allowed the same color, and that asymmetry is where the marks go.
What is the School Crossing assembly often mistaken for?
The School Advance Crossing assembly (S1-1 with an AHEAD or XX FEET plaque), which warns the crossing is further on. The plaque is the only difference between them.
