A private member’s bill by Labour MP Iain Lees-Galloway was drawn from the ballot this week, and Parliament is expected to vote early next year on whether to lower the alcohol limit from 80mg to 50mg per 100ml of blood.
The Herald on Sunday called for the change with the “Two Drinks Max” campaign.
Among those backing the tougher stance is Harvey Roberts, whose daughter Fay died in 2011 when her boyfriend, who had been drinking, crashed while overtaking at speed.
Felipe Gacitua was under the drink-drive limit when he killed 25-year-old Fay, but a judge ruled alcohol was an aggravating factor. Gacitua was sentenced to three years’ jail and disqualified from driving for four years.
