School Zone and Pedestrian Signs
School zone and pedestrian signs protect the most vulnerable road users. The exam tests the pentagon school sign, fluorescent yellow-green color, school speed limit plaques, and the rules for school buses and crossing guards.
Core rules
- The school sign is a five-sided pentagon pointing upward, with a black legend on a fluorescent yellow-green background. It is the only standard pentagon-shaped sign.
- School speed limits are posted on white regulatory plaques, often "20 MPH WHEN FLASHING" or "SCHOOL DAYS 7 AM–4 PM." The limit is enforceable only during the stated times or when the beacons flash.
- A crossing guard has authority to stop traffic. Stop when the guard raises a stop paddle or steps into the roadway.
- Pedestrian crossing signs are fluorescent yellow-green diamonds or rectangles; crosswalk markings may be parallel lines or continental bars.
- School buses: on an undivided road, stop for a school bus with red lights flashing and its stop arm extended, in both directions. On a divided highway with a median, traffic on the opposite side does not stop.
- Pedestrian signals: a flashing hand means do not start crossing; finish if already in the crosswalk.
Worked example
You approach a pentagon school sign with a "20 MPH WHEN FLASHING" plaque. The yellow beacons are off at 4:30 p.m., but children are still on the sidewalk. The posted school limit is not active, so the regular speed limit applies, but the basic speed rule still requires you to slow if children are near the roadway. Do not assume the zone is irrelevant because the lights are off.
Traps
- Confusing the pentagon school sign with a diamond warning sign.
- Treating fluorescent yellow-green as standard warning yellow.
- Assuming school zone hours are the same everywhere.
- Stopping for a school bus on the opposite side of a divided highway when no stop is required.
