'It is misleading for proponents of John Butterfill's bill to claim that there would be a significant reduction in road accident casualties in Scotland. Such claims are based on historical research which does not take full account of specific and current Scottish circumstances.
'Previous studies have been based on the 1968-71 British Summertime (BST) experiment and since then there have been great improvements to road design, streetlighting and other road safety measures.

'This analysis examines all Scottish accidents over a recent five year period in terms of the season of the year, the time of day the accidents took place and the prevailing light conditions measured relative to more than 20 locations in Scotland.
'The results of our new analysis will show that the effect of a change to Central European Time would be broadly neutral in terms of total road accident casualties in Scotland.'
