    School zone

    This fluorescent yellow-green sign has no speed tab under it. What does it ask of you?

    • A.Reduce speed when children are presentAnswer
    • B.Drive at 30 km/h at all times, day and night
    • C.Stop before entering the zone
    • D.Nothing; the sign only marks the school property

  3. 3 of 28 · Warning signs

    30 km/h

    The tab under this school zone sign shows only 30 km/h. When is that limit in effect?

    • A.From 8 a.m. to 5 p.m. on school daysAnswer
    • B.Every day from dawn to dusk
    • C.24 hours a day, every day of the year
    • D.Only while children are actually on the roadway

    Explanation: When the tab shows only a speed, that 30 km/h limit applies from 8 a.m. to 5 p.m. on school days. If the tab also shows hours, those hours apply instead. Do not confuse it with a playground zone, whose 30 km/h limit runs every day from dawn to dusk.
