Ontario road sign — Observe the lower posted school-zone speed limit
Show Answer & Explanation
Correct Answer: B. Observe the lower posted school-zone speed limit

Flashing yellow lights at a school-zone sign activate the reduced posted speed. Obeying this lower limit gives you much shorter stopping distance and more reaction time around children, who can be unpredictable near schools.

Why the other answers are wrong

  • A.Stop completely at the sign before proceedingFlashing lights at a school-zone speed sign do not require stopping; they activate a reduced speed limit.
  • C.Ignore the sign outside of school hoursWhen the lights flash, the sign is active regardless of the hour; you must obey the lower speed.
  • D.Drive at the general urban 50 km/h limitThe lower posted school-zone speed overrides the general 50 km/h urban default while the lights flash.
