The campaign has been aimed at getting motorists to reduce their speed whenever they get behind the wheel.

Last year, there were 345 road deaths in Scotland and police chiefs are hoping to further reduce the death toll on the country's roads.

Ricky Gray, assistant chief constable of Strathclyde Police, said: "We are determined to drive this figure down, as it is estimated that almost a third of all road crashes are caused by excessive speeds.

"I hope by highlighting the problems of speeding, even if only for one day, we can make a substantial impact on road fatalities."

"We are warning drivers that despite this high-profile initiative, we will be targeting those who speed, 365 days a year."
