SIR - If George Grant is so concerned about road safety in Bradford (Letters, April 13) he needs to ask why his government recently raised the speed limits in England and Wales for HGVs over 7.5 tonnes from 40mph to 50mph on single carriageways and from 50mph to 60mph on dual carriageways.

Road safety groups have condemned the decision as short-sighted and runs against work to more effectively manage traffic speeds and reduce casualties on our roads.

The relationship between speed and casualties is a proven one.

Allowing the largest vehicles on our roads to reach higher speeds more often risks more deaths, serious injuries and additional costs to the tax payer.
