Special constables could soon be clamping down on speeding motorists.
Fenland police will soon be piloting a scheme in which communities can contact police to raise concerns about speeding hotspots.
These will then be targeted by the volunteers, who have the power of arrest.
Cash-strapped Cambridgeshire Police is looking at ways to save £19.3 million before 2019.
Fenland’s Insp Will Davies said: “As we continue to review and scrutinise our working practices we are becoming ever dependant on the service we are provided from volunteers within the community.
“As most people will know we have a long-standing working relationship with the specials who volunteer their own time every month to work alongside regular police officers to keep our communities safe.
“One of the many ways that the specials are supporting us in Fenland is by conducting speed enforcement at our most vulnerable locations.
“We are soon to pilot a system where the community can message a mailbox for their area to request police address a perceived speeding concern.
“This mailbox will be managed by our special colleagues who will, in turn, respond by targeting the most vulnerable sites.
“We will then use social media to feed back what activity has taken place.
“This is just one example of how the special constabulary continues to support local policing in keeping our towns and villages safe.”
