Road Signs
In Ontario signage, a red circle with a line drawn through a symbol means:
Show Answer & Explanation
Correct Answer: C. The activity shown is not allowed
The red-circle-with-slash is a universal Canadian regulatory symbol for prohibition. Whether it overlays a vehicle, arrow or action, it means that activity is legally banned at that location. Recognising the shape lets you respond even before reading any text.
Why the other answers are wrong
- A.The activity shown is recommended but not requiredA red circle with a slash is a mandatory prohibition, not a recommendation; advisory signs are yellow diamonds without the red circle.
- B.The activity shown is only allowed during certain hoursTime-limited restrictions add explicit wording (hours) beneath the sign; a bare red-circle-slash applies at all times.
- D.The activity shown must be done at reduced speedA red-circle-slash means 'not allowed' — not 'allowed at reduced speed'; speed restrictions use rectangular 'MAXIMUM' signs.
