Mobile safety cameras will be used at seven new sites across Derbyshire in a bid to reduce motorcycle accidents.
The initiative will run every Sunday until the end of September, with areas popular with bikers being targeted.
Camera bosses said they hoped it would persuade motorcyclists to stick to speed limits and reduce casualties.
In 2004, there were 144 collisions involving motorcycles on the county's roads. Ten people were killed and 145 people were seriously injured.
The new locations to be targeted are the A621 Ramsley Moor, A621 Baslow , A619 Pilsley, A515 Monyash, A515 Hartington,A 515 Newhaven and the A5012 Elton Common.
