New figures showing a spike in the number of speeding tickets handed out by police last year will do nothing to silence those critics who claim the fines are nothing more than a revenue-gathering device.
In 2010, police handed out 627,948 tickets for speeding infringements, compared to 329,838 in 2009.
The 2010 figure was more than 200,000 above the four-year average for tickets issued, which tends to suggest a particular surge in that year, rather than a slow and steady climb in the number of tickets issued over the preceding years.
The revenue gathering argument is a flawed one, and it's a theory normally trotted out by disgruntled motorists who have themselves just been pulled over, or snapped by a speed camera.
There is some merit in the points put forward by national road policing manager Superintendent Paula Rose, who as well as dismissing fears that the tickets were simply a way of bringing in money, pointed out that the increased number of issued tickets could have been affected by the reduction in police tolerance for speeding during holiday periods, as well as the introduction of new digital speed cameras.
