The aim of these piggy banks is to monitor the speed of passing cars.
But mobile speed cameras have also been catching drivers in the North East for other crimes such as using a phone behind the wheel and illegal number plates.
Recent figures released by the Northumbria Road Safety Initiative prove almost 700 motorists were snared by the cameras for offences other than speeding. Doubling up the fines and points.
Top of the list was drivers not wearing their seat belts, with 604 people being penalised during a four-month period.
The numbers show between August and November in 2015, the latest available, 37 motorists were caught committing the offence on the A193 Church Bank in Wallsend – the local hotspot.
Other hotspots for people not wearing their seat belts are:
A185 Jarrow Road, South Tyneside – 33 people
A167 Stamfordham Road, Newcastle – 32 people
A1171 Dudley Lane, Cramlington, Northumberland – 29 people
A191 Whitley Road, Benton – 26 people
Springwell Road, Sunderland – 26 people
A183 Dame Dorothy Street, Sunderland – 26 people.
Not to mention the 52 motorists that were caught using a phone behind the wheel during the four-month period.
Five drivers were snapped on the A188 Benton Lane in North Tyneside and another four on the A690 Durham Road in Sunderland.
Under new laws introduced in March, the punishments for using a phone behind the wheel has increased to six penalty points and a £200 fine.
New drivers could also have their licence revoked if they rack up six points in their first two years.
That means retaking your practical and theory tests before being allowed back on the road.
Using your phone while driving is pretty daft anyway so unless your hands free don’t answer the call.
A total of 36 drivers were caught for “other offences” such as not being in control of their vehicle or using illegal number plates over the four months.
Superintendent Sarah Pitt, head of operations at Northumbria Police, said: “Camera detection is a great tool used to help police enforce all road laws and legislations.
“Many think speeding is the only thing detected however, driving without a seat belt, using mobile phones behind the wheel and more can all be identified and are all actions which make our roads a danger for motorists and pedestrians.
“We need to ensure we take positive action whenever possible to keep dangerous drivers off our roads. These laws are in place to protect people – and quite simply breaking them can cause serious injury or even death. We don’t tolerate it and those in violation will face the consequences.”
As much as these are about safety, these cameras are just becoming a huge money spinner for the police force. So don’t loose your hard earned cash or your licence.
