Introduce and enforce speed limit of 20 mph on all urban roads, 40 mph on rural roads/lanes and 60 mph on all other trunk roads.
Older people hit at 30mph face a 47% fatality risk and are 10 times more likely to die than if the vehicle was travelling at 20mph . In addition at 20mph fewer collisions occur as there is more time to avoid a crash. 20mph zones are effective at reducing the toll from collisions , cost as little as £2 per head  and are popular with residents and local businesses.
Almost half of all road deaths in 2010 were on single carriageway rural roads with a 60mph speed limit . The department for transport has encouraged councils to implement 40mph zones, however this proposal leaves many country tracks with a speed limit only 10mph slower than on a motorway. Finally 60mph limits are already being considered for the motorway network , with higher speeds causing stop-start jams at busy times and increased accident rates and severity.
Speed limit reductions are already being implemented in local areas all over the country and are a cost effective method to increase road safety. However these need to be rolled out across the board to improve safety on all roads.
