A traffic island can be a median strip, a strip in the middle of a road. It can also be a narrow strip between roads that intersect at an acute angle. Some traffic islands may serve as refuge islands for pedestrians. Traffic islands are often used at partially blind intersections on back-streets to prevent cars from cutting a corner with potentially dangerous results.

In parts of the United Kingdom, the term island is used as a synonym for roundabout.

It also is a Finnish band whose debut album is "Enough is Enough"
