From 6pm on 20 November, in 11 Scottish council areas will move to Level 4 for 3 weeks it has been announced.
Other measures under Level 4 include:
Scotland’s First Minister, Nicola Sturgeon, said continued and significant concern about levels of the virus in all of the council areas that would be moving to the highest tier of restrictions saying “The infection rate in all of these areas remains stubbornly and worryingly high.
"At these levels, we simply do not have the assurance we need that hospital and ICU services will be able to cope as we go deeper into winter."
The Scottish Hospitality Group, which represents some of the country's biggest pub and restaurant chains, said the fact that Covid cases in many Level Three areas had not fallen despite licensed premises largely being closed showed that household transmission was the biggest driver of the virus.
Glasgow Chamber of Commerce described the news as "devastating" and called for more emphasis on mass testing to avoid "a miserable cycle of lockdowns" through winter.
