The Scottish Government is calling for more powers to toughen up on drink-driving ahead of a debate at Holyrood this week.
Justice Secretary Kenny MacAskill has written to UK Transport Secretary Patrick McLoughlin asking for powers over breath testing, drink-drive penalties and differential limits to be devolved to Edinburgh.
The SNP wants to lower the maximum permitted blood alcohol limit to be lowered from the UK level of 80mg per 100ml of blood to 50mg, bringing Scotland into line with countries such as France, Germany, Spain and Ireland.
The government is also considering introducing more random breath tests and lower alcohol limits for young drivers and people who have just passed their test.
The Reported Road Casualties Scotland 2011 report showed that an estimated 750 casualties including 20 deaths were due to drink-drive accidents in Scotland in 2010.
Mr MacAskill said: "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."
