M4 speed cameras generate half a million pounds
Speed cameras on the M4 in Port Talbot have generated more than £500,000 in fines within six months.
The two mile stretch of motorway is covered by average speed cameras and operators 'GoSafe' said there were around 50 offences every day, a "small proportion" of the 75,000 vehicles using the road.
Manager Chris Hulme insisted that the cameras are there to ensure road safety, not make money.
However campaign group Safe Speed argues cameras are not necessarily the best way to get motorists to slow down:
On Sunday, a police boss in North Wales argued that speed cameras should not be seen as revenue raisers.
