Roundabout Ahead

Warning sign · MUTCD W2-6

Roundabout Ahead

A roundabout is ahead. Three arrows chase each other counterclockwise around a central island.

Shape
Diamond (square turned on its corner)
Color
Yellow background, black arrows and border

What to do

Slow down, watch for the yield signs at the entrance and be ready to give way to traffic already circulating. Enter only when there is a safe gap, keep to the right of the central island and signal when you exit.

Where you see it

On the approach to a roundabout, before the yield line and the splitter island.

Test trap

The sign warns you; the yield rule applies at the entrance, not before it. Drivers often think they must stop or that vehicles entering have priority, but traffic already in the circle goes first.

Memory tip: Arrows go round counterclockwise: slow down, yield, then go.

Practice question

This sign means:

  1. A traffic signal is ahead
  2. A roundabout is ahead
  3. The road ends in a U-turn
  4. Traffic merges from the right

Answer: B. The three arrows circling counterclockwise warn of a roundabout ahead.
