organised in the UK
to protest against rising fuel tax
On August 1, 2000 and every Monday thereafter, Britain's motorists are being encouraged to boycott buying petrol. Of course, they will still need to buy petrol (so I imagine that the petrol stations will be busier than normal on the days directly before and after these campaigns), but presumably the idea is to make a point.
The Dump the Pump campaign made very little impact. In August we saw direct action taken by farmers and lorry drivers (including the drivers of petrol tankers). You can read all about it at Petrol Crisis
