Justice Secretary Kenny MacAskill has also asked the UK transport secretary for the transfer of powers in areas such as random testing and tougher measures for young drivers:
This government welcomes having the power to set the drink-drive limit but the Scotland Act was a missed opportunity.
The very limited transfer of powers did not go far enough.
We wanted a package to be devolved that would allow us to consider whether the police should be able to carry out breath testing drivers anytime, anywhere, and powers to consider changing the penalties for drink-driving.
We also called for the chance to consider differential drink-driving limits. For example, for young and novice drivers.
None of these were devolved by the UK government and I have written to the Secretary of State for Transport calling for the UK government to reconsider.
