Road Signs

A yellow diamond warning sign with a speed number (e.g., '50 km/h') below a curve symbol means:

Ontario road sign — A recommended safe speed for the curve — not a legal limit
Show Answer & Explanation
Correct Answer: B. A recommended safe speed for the curve — not a legal limit

Advisory speeds are engineering recommendations — going faster risks leaving the road on the curve, but it is not a ticketable speed limit. The posted legal limit (white regulatory sign) still applies.

Why the other answers are wrong

  • A.The speed limit becomes 50 km/hAdvisory speed does not change the legal limit.
  • C.Speed cameras aheadCamera warnings use specific photo-radar signage.
  • D.Maximum truck speedTruck-specific rules use separate signs.
