UK freight services workers and other members of the public have said that rising fuel prices are their top concern when it comes to transport issues. In a poll carried out by the RAC Foundation, 68 per cent of motorists said the cost of petrol and diesel worries them more than any other road-related problem as they struggle to cope with the expense of filling their tanks.

Earlier this month, the Federation of Small Businesses found that almost eight in ten small businesses have been harmed by the high cost of fuel. How has the cost of fuel affected you?
