Using Roundabouts Safely

A roundabout is a circular intersection where drivers travel counterclockwise around a center island. There are no traffic signals or stop signs in a modern roundabout. Drivers yield at entry to traffic in the roundabout, then enter the intersection and exit at their desired street.

Roundabouts have been used in Cranberry for more than a decade, with the first introduced on Longtree Way in 2009 as part of the expansion in Cranberry Woods. More followed on Glen Eden Road, Cranberry Springs Drive, and North Boundary Road.

A recent PennDOT study found that roundabouts offer improved safety primarily because there are fewer conflict points at slower speeds with easier decision making.   More info from PennDOT...

Approaching and Entering a Roundabout

  • When approaching the roundabout, slow down and be prepared to yield to pedestrians in the crosswalk.
  • Approach the Yield Line, look to the left and check for approaching traffic within the roundabout. Circulating traffic has the right of way.
  • Enter the roundabout when there is a safe gap in traffic. If necessary, stop at the Yield Line until there is a safe gap in traffic.

Circulating and Exiting a Roundabout

  • Once you have entered the roundabout, proceed counterclockwise to your exit point. You now have the right of way.
  • As you approach your exit, use your right turn signal.
  • Watch for pedestrians in the crosswalk and be prepared to yield.
  • Exit the roundabout.
Roundabout Safety

Be Aware Of

  • Emergency Vehicles - Do not enter the roundabout when emergency vehicles are approaching - pull to the side. If you are in the roundabout, exit at your intended exit then pull to the side. Do not stop in the roundabout.
  • Large Trucks - Roundabouts are designed to accommodate fire trucks and other large vehicles. A truck apron is provided around the central island for truck trailers to use, if necessary. The truck apron is several inches higher than the roadway pavement to discourage cars from using it.
  • Bicyclists - Bicyclists have the option to travel as a vehicle or as a pedestrian when using a roundabout. When traveling as a vehicle, they will follow the same rules. Never overtake a bicyclist within a single-lane roundabout.
  • Pedestrians - Motorists must yield to pedestrians when entering and exiting a roundabout. Pedestrians will use crosswalks and splitter islands to cross each leg of the roundabout.
