School, Pedestrian, and Bicycle Signs (school zones, crosswalks, crossing guards, shared-lane markings)
What this domain tests
This domain covers signs that protect people walking and biking, plus school-zone controls. The exam tests the fluorescent yellow-green pentagon school sign, school speed-limit plaques, crosswalk and pedestrian signs, crossing-guard signals, and shared-lane markings. In Maine, school and pedestrian signs commonly use fluorescent yellow-green because it is more visible than standard yellow in low light and bad weather.
Core rules
- The school sign is a five-sided pentagon, normally fluorescent yellow-green, with a symbol of children or a school.
- A posted school speed limit applies during the stated hours or when children are present, depending on the plaque.
- Crosswalk signs warn drivers to yield to pedestrians in a marked or unmarked crosswalk.
- A crossing guard's stop sign or raised hand has the same effect as a stop control; stop and wait.
- Shared-lane markings, often called sharrows, show that bicyclists may use the travel lane; they do not create an exclusive bike lane.
Worked example
A driver approaches a fluorescent yellow-green pentagon showing two children, with a plaque reading 15 MPH WHEN CHILDREN ARE PRESENT. At 4:30 p.m., children are waiting at the curb. The school sign warns of the zone; the plaque makes 15 mph the applicable limit at that moment. The driver must slow to 15 mph and be ready to stop for the crossing guard or children. The pentagon shape is the quick clue that this is a school sign, not a generic warning.
Traps that cost marks
- Treating a sharrow as an exclusive bicycle lane; it is a shared-lane marking.
- Assuming a school speed limit applies all day when the plaque limits it to certain hours.
- Ignoring a crossing guard because no children are visible yet.
- Confusing a pedestrian-crossing warning sign with a regulatory stop sign.
