Motorists using the A9 have been warned to ignore rumours that the average speed cameras are not working or face a fine.
A lack of information on the number of motorists who have fallen foul of the cameras has fuelled speculation about the effectiveness of the system, a claim categorically denied by Police Scotland.
“The cameras are operating,” said a spokesperson.
“Figures are being collated and will be available in the near future.”
The cameras went “live” on October 28 but the lack of statistics on the first month of operation prompted campaigners to claim that, until these were released, it was difficult to prove they were operating properly.
Mike Burns, spokesman for A9 Average Speed Cameras Are Not The Answer campaign, said: “I’m not surprised we haven’t heard of anyone getting a fine.
“We wonder if they are working properly. There are persistent rumours that some haven’t got power. We want to see the numbers.
“They need to prove these things are helping.”
Highland MP Danny Alexander said: “Many people have contacted me to say they are concerned about dangerous overtaking caused by frustration and drivers switching to B roads to avoid the cameras, causing ‘rat runs’.”
Transport Scotland has already claimed the introduction of the cameras has changed driver behaviour radically regardless of how many fines were issued.
“Instances of excessive speeding on the A9 have dropped from around one in 10 to less than one in 700 since the cameras were installed,” said a spokesperson.
