The number of people killed on the roads dropped 11% last year, according to government figures.
Those seriously injured in 2011 also went down 5% compared with the previous year.
Road death and injury numbers are now at their lowest-ever level, down 47% and 45% respectively since 2001, but Transport Minister Keith Brown said there is no room for complacency.
"The very latest data on reported road casualties provides encouraging evidence we are making good progress in driving down road casualties, with numbers at their lowest level since records began over 60 years ago," he said.
"Crucially the numbers of fatal and seriously injured are falling but, as we've seen in recent days with another fatality on our roads, there is simply no room for complacency.
