THE AA has called for a national review of speed limits on all roads, coupled with an overhaul of speed signs to include information on why the maximum speed is set as it is. The call comes following an 18-month study which claims almost all drivers - not just company car drivers and 'boy racers' - admit to speeding regularly because they can't understand the reasons for limits imposed on many UK roads.

'The Government is to set targets for accident reduction and speed is often a key factor in crashes. If we are to tackle the problem, it is vital that we get to the heart of why people do it in the first place,' said AA policy director John Dawson. 'A review of all roads to assess limits should be carried out so that drivers can have more confidence that there is a good reason for them. Signs should be accompanied by an extra statement if necessary, such as 'school', 'severe bends' or 'dangerous road'.
