Road safety campaigners have expressed their concern that a local authority may remove every single speed camera in an entire county in order to make financial cuts.
Thames Valley Safer Roads Partnership will no longer be receiving its £600,000 funding from Oxfordshire County Council, as the authority attempts to cut £11 million of spending from its budget.
All of the county's 72 fixed speed cameras could be switched off as the partnership takes steps to cease all enforcement, possibly as soon as the beginning of next month.
In following through in its pledge to end central funding for fixed speed cameras, the Government has said it is keeping its promise to "end the war on the motorist".
Getting caught speeding can makecar insurance cover more costly.
Road safety campaigners fear other councils struggling to make ends meet could follow suit, resulting in lives being put at risk.
Every week three people are killed and more than 150 are injured on roads in the Thames Valley, according to statistics from the partnership.
Councillors at a special meeting will vote on whether to ratify the move to scrap the funding on Tuesday.
Ministers acknowledged that "difficult choices" must be made but they hoped councils would use available funds for other road safety measures.
Ellen Booth, a campaigns officer for road safety group Brake, said: "It would be a disaster if these cuts were passed on in full by county councils to road safety partnerships.
"It would be especially hard to justify the idea that all speed cameras should be turned off. Speed cameras are a really cost effective way of managing speed, which is one of the biggest issues on our roads.
"To get rid of them would be a backward step and we would really be risking people's lives."
