Northamptonshire County Council is considering axing mobile speed cameras.
Councillors will vote imminently on whether to remain in the safety camera partnership, after it was suggested that cameras were more of a hazard than a help.
Council leader Jim Harker said: 'There are benefits, but there is evidence that people tend to react quickly to cameras and slow down sharply, creating hazards and possibly accidents.'
The council is voting on whether to stop using mobile speed cameras, not static cameras, which would remain in place.
The funds saved by not having the cameras would be spent on safety alternatives, such as sleeping policemen and increased road lighting.
