A roundabout is a one-way circular intersection designed to reduce congestion and maximize safety. There are several roundabouts in Clarington, including three multi-lane roundabouts at the Holt Road and Highway 401 interchange.

For those residents unfamiliar with the rules governing roundabout use, here's some useful information.

Tips for driving multi-lane roundabouts

  • Slow down and yield to vehicles in the roundabout
  • Watch for signs that help you decide what exit to take
  • Watch for signs and road markings that help you decide what lane to enter from
  • Watch for pedestrians in the crosswalk, and be prepared to stop
  • Give extra space for large trucks, they may need to use both lanes entering and circulating
  • Yield to traffic already in the roundabout that comes from your immediate left
  • Enter the roundabout when there is a gap in traffic
  • Do not enter and merge beside a vehicle or cyclist already circulating, even if it is travelling beside the central island
  • Travel counter-clockwise
  • Do not stop inside the roundabout. You have the right-of-way over entering traffic
  • If you are in the roundabout when an emergency vehicle approaches, exit as normal and proceed beyond the splitter island before pulling over
  • Maintain your lane position as you circulate
  • When approaching your intended exit, signal right and exit the roundabout
  • As you exit the roundabout watch for pedestrians in the crosswalk and be prepared to stop
  • Never make a left turn as you enter a roundabout

Always obey the signs and markings
