Until now most partnerships were reluctant to admit which cameras were the biggest earners, normally only releasing the information following a Freedom of Information application.
But under proposals drawn up by Mike Penning, the road safety minister, they will have to publish information to justify the use of cameras.
"For the first time people will be able to see whether their local cameras are really cutting accidents or just being used as cash cows," said a Whitehall source.
One Gatso at the southern end of the M11 in Essex raked in £2.3 million in fines over five years. Others earn safety camera partnerships several hundred thousand pounds a year.
It is the latest move by the Coalition, which said it wanted to end the "war on the motorist".
