Question: A plain black-on-white speed limit sign (without the word 'maximum') represents:

Answer options:

• An advisory speed ✅ The legal maximum speed
• The minimum speed
• The school-zone speed

Correct answer: The legal maximum speed

Explanation: Under the Québec Highway Safety Code, rectangular white signs with black lettering are regulatory signs that establish the absolute legal maximum speed limit permitted under ideal driving conditions. In contrast, yellow-and-black signs indicate advisory speeds for specific hazards like curves, minimum speed limits feature distinct designs with specific thresholds, and school-zone limits are marked by pentagonal shapes. SAAQ examiners frequently test the distinction between regulatory white signs and warning yellow signs to ensure drivers understand which limits are legally binding versus merely recommended for safety.
