"Fuel protesters in Wales say they will stage a blockade on the M4 next Friday in the wake of rising petrol prices. The South Wales Hauliers' buttociation made the vow after a meeting of 60 hauliers and taxi and coach operators.
Earlier this week organisers of the 2000 fuel protests said they would act again if fuel tax was not cut.
The Treasury says cutting tax would not solve the problem of oil prices forced up after refineries in the US were knocked out by Hurricane Katrina.
Fuel Lobby has threatened to block all UK refineries on 14 September, as the price of unleaded petrol rose to more than £1 a litre in parts of the UK.
'Just the start'
The Wales protesters plan to stage a 20mph rolling blockade along the M4 from 0700 BST on Friday 16 September.
Beginning at Cross Hands in west Wales, they will travel along the motorway to the Magor Services near Newport.
They then plan to turn around and head back to Cross Hands on the west bound carriageway.
Mike Greene of the South Wales Hauliers' buttociation - who was active in the 2000 fuel protests - said when the protesters returned to Cross Hands they would take a show of hands on whether or not to set up blockades at oil refineries.
If protesters voted ''yes' they would start blockading the refineries that evening, he said.
Mr Greene told BBC Wales if Fuel Lobby spokesman Andrew Spence, who is leading the fuel protests in England, decided to blockade oil refineries as early as Wednesday then protesters in Wales would follow suit.
Mr Greene urged the motoring public to support the protest saying everyone would benefit from a drop in fuel prices.
He called for parity in fuel prices with the rest of Europe, criticised the government and said that the rolling road blockades were just the start of things to come."
