Truck drivers surrounded the Irish Insurance Federation's (IIF) Dublin offices on Monday to protest at spiralling insurance costs.
Six hauliers parked their vehicles outside the offices, while another six circled the block for two hours, amid morning rush-hour traffic.
Irish Road Haulage Association (IRHA) spokesman Gerry McMahon said hauliers were tired of the "rhetoric" spoken about reducing insurance costs at their numerous meetings with insurers.
"It's all talk and no one's doing anything," he said.
An IIF spokesman blamed the high cost of motor insurance on structural problems specific to the Irish system, such as the high cost of claims and awards.
"We'd encourage the government to expedite the Personal Injuries Assessment Board, but an election date is about to be announced and it doesn't look like it's going to happen in this government's lifetime," he said.
