A massive protest is planned for tomorrow on several routes into Dublin city as well as within the city centre.
It's being organised by the Irish Truckers and Haulage Association Against Fuel Prices.
It's expected to cover routes including the M1, M2, M3, M4, M7, and the M11, with vehicles travelling in convoy to Leinster House, starting at 7am.
Gardai are warning that the protest may impact commuter traffic, and they're advising people who plan to travel to Dublin to plan accordingly.
In a statement the organisers say: "This protest is for lower fuel costs at the pump and at home. This is for the people of Ireland, we are all suffering some more than others.
"We want the government to address the nation on this cause.
"If we don't get a change a lot of small operators will be out of business sooner than you think.
"If we don't get an answer we will be back in bigger numbers for a week before Christmas."
In a statement, Gardai say: "An Garda Síochána is aware of a potential protest in the Dublin Region tomorrow, which may impact on early morning commuter traffic. Commuters intending to access or travel through the Dublin region should plan accordingly.
"An Garda Síochána will have an appropriate and proportionate plan in place to monitor the protest.
"An Garda Síochána will provide update traffic information on our social media channels as and when required."
