DRIVERS break the speed limit to make up for lost time after going past cameras, claims a survey out today.
But Philip Gwynne, spokesman for the West Yorkshire Safety Reduction Partnership which places speed cameras, said findings in a new report stating drivers slow for cameras and then break the speed limit do not match the extensive studies they have done.
The survey, by windscreen experts Autoglass, claims 72% of drivers in Yorkshire flout the Highway Code by breaking speed limits after cameras.
Mr Gwynne said: "We often do surveys where we check speeds on roads with cameras and our findings are much different from those in the Autoglass report.
"Last year 102 people were killed or seriously injured on West Yorkshire's roads, that is a massive reduction and we believe it is due, in some part, to drivers slowing down.
"Some people do, of course, speed up between cameras but findings from Bradford University have actually proved they won't get there any quicker as they keep having to slow down sharply."
The report also showed two thirds of drivers admitted to driving aggressively around traffic calming measures and three quarters would jump amber lights and use rat runs to save time lost by slowing for cameras.
Managing director of Autoglass, Nigel Doggett said: "The effectiveness of traffic calming measures in improving safety at danger spots has been clearly proven but it seems they are having an adverse effect on drivers behaviour elsewhere.
"This suggests that more needs to be done to ensure that Yorkshire drivers understand that road safety measures are genuinely working to keep them safe, not to inconvenience them."
Mr Gwynne believes the publicity surrounding speed cameras has made people think about how fast they are driving.
He said: "A good example is Manchester Road where drivers have changed their habits and are now driving much slower than they did before the cameras.
