The political messages are part of a campaign run by anti-nationalist group The Majority, which also organised for a plane towing a banner saying #ResignSturgeon to be flown over Edinburgh and Glasgow this afternoon.
The three targeted billboards are at Clydeside Expressway in Glasgow, Slateford Road in Edinburgh and Market Street in Aberdeen and are part of a series of campaigns the group is heading in the lead up to the Scottish Elections on May 6.
In a statement on The Majority’s website it explains the campaigns are a message to Nicola Sturgeon to “take responsibility” for her government’s “catastrophic handling” of the Alex Salmond harassment inquiry.
At a landmark hearing earlier this week, Ms Sturgeon gave evidence to the Scottish Parliament’s Committee on the Scottish Government Handling of Harassment Complaints during which she said she felt “very let down” by Salmond.
Mark Devlin of The Majority said: “We represent the silent majority of people in Scotland, who are angry and frustrated by Nicola Sturgeon’s shenanigans bringing international shame on Scotland.
“The Scottish public deserve a Parliament and First Minister above reproach and want the Scottish Government to focus on health, education, jobs and the pandemic.
"Instead we have a First Minister misleading parliament, breaking the ministerial code and withholding information from an inquiry into her government’s unlawful, unfair and biased actions against Alex Salmond, all while totally neglecting her day job."
Grassroot movements Scotland Matters and UK Union Voice are also behind the #ResignSturgeon campaign.
