The team which puts up speed cameras across Derbyshire say they expect to face a hostile reception at some of the county shows this summer.
The Safety Camera Partnership will visit a dozen venues to warn people of the dangers of speeding.
Visitors to the shows will be given a chance to meet police officers and to operate a camera.
Rebecca Hampson, from the partnership, said it gives them a chance to put their case across.
"It is possible that people will be angry and we have had people in the past being like that, but that is what we are all about really.
