Two Derbyshire sisters who lost their parents in motorbike crashes have launched a speed-reducing campaign.
"Operation Focus" is being run on routes highlighted as collision black spots, including the A6 between Whatstandwell and Cromford.
The parents of Melanie and Kerry Smith died in separate motorcycle accidents.
British superbike star Leon Haslam joined the sisters in Monday's launch of the scheme - which aims to get bikers to slow down.
Melanie Smith said bikes designed to do excessive speeds were also being targeted.
"My mother died four years ago, my father died two years ago in October. So we're just trying to make people aware, really, of the tragedies (these bikes) do cause," she said.
From Monday safety camera teams will target identified routes, including the A6 near Cromford.
