Scotland cuts drink-drive limit
A new law has come into force which makes the legal drink-drive limit in Scotland lower than elsewhere in the UK.
The change reduces the legal alcohol limit from 80mg to 50mg in every 100ml of blood.
Campaigners believe the new limit will cut the number of deaths and serious injuries on Scottish roads.
The limit elsewhere in the UK will remain at 80mg - the joint highest in Europe.
