Roundabout Ahead Sign
A roundabout is ahead. The circular arrows show the direction of travel around the island.
What to Do
Slow down and choose the appropriate approach lane before entering.
A Detail to Remember
The 300 m plaque is an advance-distance example. It describes how far ahead the roundabout is, not its size.
Roundabout or Traffic Circle?
Ontario’s handbook distinguishes modern roundabouts from older traffic circles. Modern layouts use entry deflection and splitter islands to slow approaching vehicles, with entering traffic yielding to vehicles already circulating.

Yellow warning signs ask you to anticipate a condition ahead. Read any distance or speed plaque with the main symbol, then adjust to what you can actually see on the road.
