Scotland's first police motorbike to be fitted with a speed camera has been launched in Edinburgh.
The motorbike has a speed-scope camera and video
Lothian and Borders Police Officers plan to use it in areas where roadside conditions stop vans from being used.
The brightly marked Honda 650 Deauville will only go to sites where there is a history of road collisions.
The force's Chief Constable Paddy Tomkins warned the devastating impact of speeding should never be underestimated.
The motorbike will follow the same strict rules which apply to speed camera vans.
The police officer who will be operating the motorbike will have to park at a designated site before setting up the camera.
By pointing the equipment at moving vehicles before pressing the trigger the officer will be able to read the speed of cars.
However the motorbike does not flash so motorists may be unaware they have been caught speeding until they receive a letter in the post.
Mr Tomkins said four mobile safety camera vans covering 44 sites , 61 fixed camera sites and 25 red light camera sites already operated in the area.
"The introduction of the motorbike is another great example of Lothian and Borders finding an innovative solution to a problem that needed attention.
'Loss of life'
"Speeding can have a very serious effect, not only can it result in loss of life, but also a loss of livelihood.
"The devastating impact that speeding can have should never be underestimated."
Steve Stradling, professor of transport psychology at Napier University's Transport Research Institute, said: "A recent study has shown that drivers who have been caught speeding by a speed camera are twice as likely to have a collision than those who haven't been caught."
The motorbike is being operated by Lothian and Borders Police Safety Camera Partnership.
