This mandatory direction sign signals a compulsory roundabout, requiring you to follow the indicated path to ensure traffic order and safety. Mastering its meaning is crucial for your Icelandic theory test revision and navigating junctions correctly.
Roundabout is a mandatory sign used where traffic has to move in a particular way to stay safe and orderly. It often appears at islands, central refuges, one-way arrangements, path networks, and places where separating traffic streams matters more than driver preference. The sign should be read together with arrows, lane markings, kerbs, and the physical road layout because those details show exactly how the instruction is applied on site. Ignoring a mandatory sign can place you into direct conflict with opposing traffic, pedestrians, cyclists, or a protected part of the road space.
This sign makes roundabout circulation compulsory for the road user or lane concerned. You must follow the direction, side, or path shown instead of choosing your own line through the location.
