Hampshire County Council says that while it welcomes targets set by the Department for Transport to cut deaths and injuries, those for some low-risk roads are unrealistic.
Roads with an already low casualty rate have been set a target for accident
s to fall 33 per cent by 2020.
The council has called on the department to lower its targets set out in its A Safer Way report.
The council recommends higher targets be set in high-risk areas but that low-risk areas should have targets set lower.
Councillor Mel Kendal, executive member for environment at Hampshire County Council, said: 'We have invested a great deal in road safety programmes both in terms of engineering schemes and education.
'In Hampshire, we are of the view that there are many benefits to be gained if local authorities can work more closely together. In terms of meeting the targets we have suggested that significant improvements could be made by working in this way to share best practice and to pool resources.
'We value the opportunity to contribute our views and share the benefit of our experience in addressing road safety.
'We hope that the DfT will give full consideration to our response in developing the policies and guidelines that will shape road safety measures for the next 20 years.'
