At least 1,500 taxi drivers protested in Dublin this afternoon over the issue of taxi licences.
Gardaí are warning of possible rush hour delays for motorists as drivers make their way back to the Stillorgan, Clondalkin and Swords areas.
Earlier, protestors assembled at Merrion Square after making their way from three separate meeting points at Liffey Valley Shopping Centre, Stillorgan Shopping Centre and Airside Retail Park
Gardaí say there were at least 1,500 in attendance.
It is the fifth protest by the group calling itself Taxi Drivers for Change.
Taxi drivers claim that, since the deregulation of licensing in 2000, the number of taxis in Dublin has risen from 2,000 to 25,000.
They say too many taxis are currently operating and as a result it is impossible for drivers to make a living.
Taxi Drivers for Change wants the industry to be restructured and the issuing of new licences to be suspended.
The Department of Transport acknowledged that taxi drivers are facing genuine difficulties.
However, a spokesperson said the Minister for Transport is waiting for the Commission on Taxi Regulation to report before he makes any further comment.
