There's a general shortage of HGV drivers across Europe at the moment. The shortage didn't cause fuel pumps to run dry, though. It was the result of panic caused by the media after they got their hands on a document, with the initial news being that BP had closed 5 petrol stations. It escalated very quickly from there due to relentless media coverage. You could certainly argue the shortage of drivers made it much more difficult to cope with the panic once it was in full flow.
