Cambridgeshire Police are continuing their month long motorcycle safety campaign.
Figures show five bikers were killed and 84 seriously injured in crashes in the county last year.
Officers are targeting riders that break the law and are issuing advice to try and reduce the risk of them being involved in a collision.
Inspector Mark Rogers from the road policing unit, told Connect FM: “Although motorcyclists are responsible for their own safety we can only reduce the number of deaths and serious injuries if other motorists play their part.
“Unfortunately motorcyclists remain extremely vulnerable road users and it is vital that motorists remain alert and aware of who they are sharing the road with. This is particularly important when approaching bends and junctions.
“We will be targeting those riders and drivers whose poor driving and riding puts them and others at risk throughout August, using unmarked police vehicles to target those riders and drivers breaking the law.
