A report has claimed that targets to reduce the number of casualties on UK roads should be altered.
Greater consideration should be given to where people live and the target for people aged up to 16 should be extended to those aged 25, the Parliamentary Advisory Council for Transport Safety (Pacts) said.
It said that the age should be extended after figures showed there had been a 50% reduction in the number of children aged up to 16 killed and seriously injured on roads.
The report also claimed that the targets needed to take into account the frailty of many older road users. It said that figures should focus more on this age group, as an ageing population means more older drivers on the roads.
Figures also showed that men aged between 20 and 40 were six times more likely to be killed on the roads than women. However, the report said that road safety targets set for 2010 had been met.
But Pacts said the reductions achieved had differed across Britain, "with some of our road users at much higher risk of being killed or seriously injured than others".
Officials said that the next stage of the strategy will see targets set using a more sophisticated approach - taking into account area and user type.
Pacts executive director Robert Gifford said: "It is important to recognise that crashes can happen anywhere on our road network. Society has a moral duty to act to prevent the occurrence of crashes when the cause is known and there are cost-effective methods of preventing them."
