Dual carriageways to have 80mph limit?

Earlier this year it was revealed that the Government was planning on upping the motorway speed limit to 80mph. Partly to put us in line with the rest of Europe and partly, a cynic may suggest, so the Conservatives could win the motorists' votes (they'd win more by lowering fuel duty, mind).

A full consultation into whether the rise is feasible will appear in the new year, but it's been revealed that it may precede a consultation into raising the limit on dual carriageways, too.
