questions

1. An octagonal red sign at an intersection requires you to do what?

   • Come to a complete stop, then proceed when it is safe This answer is correct
   • Slow down and proceed if the way looks clear
   • Stop only if another vehicle is approaching
   • Yield to traffic on your left only

   The eight-sided red sign is the only sign with that shape, so it can be recognised from behind or in poor visibility. It requires a complete stop at the stop line, crosswalk or edge of the intersection, whichever you reach first. You may proceed only after stopping and only when the way is clear.

2. What does a yellow diamond-shaped sign tell you?

   • A hazard or change in road condition lies ahead This answer is correct
   • A law that you must obey
   • The distance to the next service area
   • Construction workers are present

   Yellow diamonds are warning signs. They alert you to something ahead that is not obvious - a curve, a narrowing road, a hidden intersection - so you can adjust your speed before you reach it. Orange diamonds carry the same shape but signal temporary construction conditions.

3. A downward-pointing triangle with a red border means:

   • Slow down and give the right of way to traffic in the intersection This answer is correct
   • Stop completely before entering
   • The road ahead is closed
   • Merging traffic must yield to you

   This is the yield sign. You must slow down, be prepared to stop, and let traffic already in or approaching the intersection go first. A yield differs from a stop in that you need not halt if the way is genuinely clear, but you must be able to stop if it is not.

4. A green circle on a regulatory sign indicates that the action shown is permitted.

   • True This answer is correct
   • False

   Ontario regulatory signs use colour as a code: a green circle means you may do the thing shown, while a red circle with a diagonal slash means you may not. Recognising the circle colour lets you read the sign correctly even if the symbol inside is unfamiliar.

5. A yellow diamond showing two children walking means:

   • A school zone or school crossing is ahead This answer is correct
   • A playground is closed to traffic
   • Children are prohibited beyond this point
   • A daycare centre operates on this street

   The two-children symbol marks a school area ahead. It warns you to expect pedestrians who may step out unpredictably and to watch for reduced speed limits and crossing guards during school hours. In some locations the sign is fluorescent yellow-green for extra visibility.
