The number of people killed on British roads fell by 16% this spring, provisional figures from the Department for Transport have shown.
There were a total of 470 deaths in the period April-June 2010, a drop on the same period last year.
The number of those killed or seriously injured (KSI) was 6% down at 6,620.
The overall casualty figure, including all deaths and all injuries, was 53,100, which is 3% down on the April-June 2009 total.
Casualty rates for all types of road user fell in the period, except pedal cyclists among whom KSIs rose 5% to 850 and total casualties were up 5%.
The report showed that child casualties, classed as deaths and injuries to those aged under 16, were down 2%.
Yet the provisional figures showed that the total of child pedestrian KSIs was 470 in April-June 2010 compared with 469 in the same period last year. The total child pedestrian casualties rose 2% to 2,210.
The biggest drop in KSIs was for car users, with the number killed or seriously injured falling 12% to 2,350.
The figures mean that the provisional number of people killed on the roads in the 12 months to June 2010 was 1,990 - a 19% dip on the previous year.
Road Safety Minister Mike Penning said he was encouraged by the figures.
"However, we are not complacent and road safety remains a key priority. We are currently reviewing all road safety policies as well as looking at the most effective way to measure progress," he said.
"We are also engaging with local authorities and other stakeholders on the future road safety agenda and will make further announcements in the coming months."
AA president Edmund King said: "This reduction is a tremendous achievement. There were 3,409 deaths in 2000, with little change over the next five years."
"It is also a tribute to all that have striven towards meeting the targets set for 2010 by the government back in 2000. Britain now desperately needs a new target to galvanise road safety actions for the next decade and beyond."
But he added the one blot on the figures was a rise in deaths and casualties among cyclists.
