Delaware Roundabouts

What is a Roundabout?

Roundabouts are circular intersections that incorporate new design features that reduce traffic accidents, traffic delays and traffic speeds when installed at appropriate locations. There are no traffic signals or stop signs in a roundabout. Most roundabouts have the following design features:

  • Yield at Entry - Traffic entering the roundabout yields the right-of-way to vehicles already in the roundabout.
  • One-Way Travel - Vehicles in a roundabout travel in one direction only (counterclockwise).
  • Central Island - A raised, painted, or landscaped central island.
  • Slower Speeds - Geometric features physically limit vehicle speeds to 25 mph or less.
  • No parking
  • No Pedestrian Access to Central Island
