As protesters remain in place at fuel terminals, here is a snapshot from around the country as of 1.30pm Friday.
The country's only oil refinery at Whitegate, Co Cork and the fuel depots in Galway city and Foynes in Co Limerick are responsible for providing fuel to roughly half the country, according to an industry expert.
Meanwhile, protest action is ongoing in Dublin city centre with vehicles continuing to line O'Connell Street.
Road closures are also in place on several motorways due to protest action.

Cork
A large Garda presence, including members of the Public Order Unit, arrived at the Whitegate oil refinery in Co Cork around 9am, asking protesters to end the blockade at the country's only oil refinery.
Access to the Port of Cork at Ringaskiddy remains restricted.
However, the build up of over 200 containers trucks and long tailbacks reported yesterday has since cleared with traffic diversions in place at Shanbally roundabout, and traffic flowing freely to and from the Roundabout on the M28.
A blockade by fuel protestors remains in place.

Galway
There are about 50 protesters at Galway Docks and they say they are adamant they are not going anywhere.
In Galway Bay, there is a tanker moored with 6 million litres of fuel on board. It can’t go anywhere because the tanks are full at the depot, given that no oil is going out.
So the situation here is that forecourts are almost empty, some are dry, and a tanker is idling on the bay with a huge amount of fuel.

Limerick
Protesters at the fuel depot at the Port of Foynes have allowed five fuel trucks to pass the blockade this lunchtime.
The fuel trucks are the first to leave the depot in four days.
The protesters say they're allowing the trucks to supply emergency services.
They are also facilitating trucks carrying animal feed and chemicals for the treatment of drinking water to leave the port, and there has been a steady and constant stream of trucks driving in and out of the port today.

Dublin
The blockade of O'Connell Street and the M50 by fuel protesters is continuing in Dublin.
At least 60 tractors and heavy goods vehicles are parked on the city's main thoroughfare as the fourth day of fuel protests continues.
The north and south quays are open to traffic, and the Luas is still operating except through the O’Connell Street area. Dublin Bus continues to run curtailed services in the city centre and says passenger numbers are down significantly.
Parts of the M50 northbound and southbound remain blocked for a second day, while sections of the M1 and N7 are also impassable.
However, TII says delays are not as prolonged as yesterday due to reduced volumes on the road network.
Dublin Bus spokesperson Blake Boland said "absolutely massive" disruption remains across the capital as a result of the blockades.
"Today being the fourth day, the disruption is still absolutely massive. We would have pretty much 1,000 buses out on the street at any one time," he said.
