Up to 500 protesters have been taking part in this year's Reclaim the Streets rally in Dublin's city.
The demonstrators blocked off Amiens Street and Parnell Street as part of their campaign to highlight the overdependence of the public on cars.
The Gardaí mounted a low-key policing operation.
There were clashes last year between Gardaí and protestors. A number of Gardaí are due in court next month as a result.
