A83, between Arrochar and Campbeltown - Serious and fatal road traffic accidents: EIR release

I am looking for the number of Serious and Fatal road traffic accidents that have occurred on the A83, between Arrochar and Campbeltown, for the most recent year that is available, and the previous ten years for comparison.

If you hold any information or analysis into what percentage of these accidents had speeding as a factor, please supply this as well.
