Petrol and diesel ran out at fuel stations after panicked drivers rushed to fill up their tanks.
Pumps were out of action at the Shell garage on Wakefield Road, Ossett, at 9am today after worried motorists drained supplies.
Usman Ali, Shell cashier, said: “We’ve got no fuel at all. The shop is open but we’ve got no petrol or diesel.
“There was a mad rush yesterday and I don’t know when the next delivery is.”
The panic was sparked after tanker drivers in the Unite union threatened to strike over working conditions and pay.
The situation spiralled into a crisis after Cabinet Office Minister Francis Maude suggested motorists should stock pile fuel incase of a strike.
Filling stations across the city experienced increased demand as people feared being left with empty tanks.
At Asda, on Asdale Road, some pumps were out of action after diesel supplies ran low.
Zena Keddie wrote on the Express Facebook site: “I was at Asda last night and when I left the tanker was there. As the pumps were empty when I went in I waited as I thought it would be easier than queuing today.
“As soon as they moved the cones all available pumps had cars filling up and some had cans too.”
At Morrisons, on Dewsbury Road, drivers faced long queues backing all the way on to Flanshaw Lane.
Queues also formed at Sainsbury’s, on Ings Road, where staff said they had been extremely busy.
And at Halfords, also on Ings Road, sales of jerry cans went through the roof as people rushed to stockpile fuel.
Ben Andrews, auto-fitter, said: “There’s been quite a big increase in sales - we’re down to the last few.”
West Yorkshire Fire chiefs have warned people against storing petrol or diesel because of a high risk of fire.
