Question: In a school zone with a posted reduced limit, you must obey the lower speed:

Answer options:

• Only when children are present
• Only on weekdays ✅ At all posted hours
• Only during arrival/dismissal

Correct answer: At all posted hours

Explanation: Drivers must obey a reduced school-zone speed limit at all posted hours because Ontario law enforces these limits strictly during the times specified on the sign, regardless of whether children are visible. Incorrect options focusing only on when children are present, specific weekdays, or arrival and dismissal times are wrong because traffic laws rely on the clear, standardized schedule displayed on the regulatory sign rather than a driver's subjective observations. On the Ontario G1 exam, remembering that posted traffic signs establish absolute, non-negotiable legal conditions rather than situational guidelines is crucial for passing the rules-of-the-road section.
