Road Traffic Signs

! During a power failure, intersection traffic lights won’t work.
  • Treat the intersection as an all-way stop.
  • Yield the right-of-way and use caution.

In Ontario, different colours on signs represent different aspects of using the road:

  • Red signs mean stop or be careful.
  • Yellow signs with black lettering warn you that you’re coming to a hazardous area or an area with special rules.
  • Orange signs with black lettering are used in areas where there is road construction.
