Speed camera chiefs have reacted to accusations of profiteering by installing signs next to sites in 30mph zones.
The Evening Mail has reported outrage from motoring groups who have accused operators of entrapment by installing cameras on dual carriageways.
One particular site on the A34 Birchfield Road has been particularly controversial. People caught there claim there is no indication that the road, which has two normal traffic lanes and an extra bus lane, is 30mph.
The West Midlands Casualty Reduction Partnership admitted drivers were confused.
Spokesman Adam Warwick said: "Contrary to popular belief we are not trying to catch motorists out with cameras; safety cameras are sited only where there is evidence that collisions, injury and death, have been caused by excessive speed."
Councils do not normally install 30mph signs on roads, but Mr Warwick added: "These are often the roads where drivers are least aware of the speed limit.
"Hopefully these signs will remind drivers that roads such as New John Street and New Town Row, in Birmingham are in fact 30mph roads, not 40, 50 and 60mph roads."
Russell Eden, from the Birmingham branch of the Association of British Drivers said: "We welcome this because a lot of these cameras take people by surprise as they don't expect many of the roads to have a 30mph speed limit.
"This leads to panic braking and can cause accidents."
More than 160 signs will be installed at 81 camera sites across the region. Birmingham, Sandwell and Solihull have already begun erecting them.
