Andorra Launches Turbo Roundabout Pilot to Cut Accidents

Andorra's Mobility Department began a pilot test of turbo roundabouts on March 3 at the Prada Casadet junction and the KM0 roundabout in Andorra la Vella.

The setup reserves the right lane solely for proceeding straight ahead or turning right where possible. Left turns are permitted only from the left lane, which also allows straight travel. Temporary signage, including illuminated panels highlighting frequent accident spots, guides drivers during the trial. If successful, the changes could become permanent.

The initiative, approved through the Mobility Table, had been scheduled for earlier in the year but was postponed for improved weather. Officials seek to better organize vehicle paths, boost traffic flow, and cut minor collisions at these high-accident locations.

Transport Secretary of State David Forné previously backed the model, pointing to its effectiveness in neighboring areas, while stressing it does not suit all junctions. The department has called on drivers to exercise caution amid the adjustments.

Mobility Andorra shared the March 3 launch via social media. The trial lacks a fixed end date but will last several months at minimum to assess results, with potential expansion to similar sites if it performs well.
