Average speed cameras are costing Scottish drivers more than £3,500 in fines every day.
In the six-month period to December, nearly 6,500 motorists were nabbed by so-called yellow vultures in three zones in the central belt.
Hundreds more were caught over the limit on the A9.
With so many drivers caught by the overhead speed gantries, it is estimated the Treasury will rake in more than £1 million in fines from Scots over the period of a year.
Detailed analysis of the camera system which uses number plate recognition technology has been carried out for the first time.
The latest available figures for the A9, which run from October 2014 to October 2015, show 5,918 drivers were caught breaking the average speed limit.
That works out at 493 a month on average.
If that trend was to continue until the end of the year, fine revenue from the cameras for the period between July and December would have amounted to almost £300,000.
On the A90, safety cameras are being used while the new Forth crossing is being built.
Just 106 drivers were caught in September, the month they went live, but the number rocketed to 839 between October and December.
Of those motorists, 282 were handed fines raking in almost £30,000 and 88 were reported to the procurator fiscal.
Transport Scotland the Scottish Government body which looks after the roads network said safety cameras deliver “excellent levels of speed limit compliance”.
“We want to see safe and responsible road use which would mean no fines being generated at all,” they said previously.
The analysis was carried out by The Sunday Post.
