The government has not ruled out hiding the locations of fixed and mobile speed cameras from the public altogether.
This week Transport and Roads Minister Andrew Constance has confirmed the government is considering removing the signage alerting drivers to the presence of fixed and mobile speed cameras.
Mr Constance cited Monash University research - which is not publicly available - found "up to 54 lives" a year could be saved if the warning signs were removed.
"This isn't revenue raising, this is about saving lives," Mr Constance said.
"Red-light speed cameras reduce fatalities by 74 per cent. The road toll is up and it's time for action."
Mr Constance said he wanted speed cameras to carry the same threat as random breath testing - that people could be caught anywhere at any time.
The on-site signage is not the only way the government identifies speed camera locations for the public.

The Centre for Road Safety also includes a list of all speed cameras on its website.
Mr Constance's office declined to respond to the Mercury's questions as to whether that list would remain publicly available.
"The NSW government has a strong road safety record and that will continue to be the case," a spokeswoman for the minister said.
"There has been no change to government policy."
Speed camera locations are chosen because they are identified as a high-risk area with a history of severe crashes.
The latest speed camera review found there had been an 80 per cent reduction in fatalities at those locations and a 37 per cent reduction in injuries.
"These cameras go into areas where there's a crash history, where the road's unsafe, where there have been people killed or injured," the NRMA's Peter Khoury said.
"These signs are effective because they tell people to slow down because they are in a dangerous location."
The NRMA is opposed to the removal of the signs because "they are an important part of the enforcement process".
Mr Khoury felt there was "no doubt" speed camera revenue would increase if the government removed the signs.
But a drop in the road toll might not necessarily follow.
"As we have seen in Victoria that doesn't actually resonate with the road toll falling," Mr Khoury said.
"The road toll in Victoria, where they don't have any warning signs, has jumped 33 per cent compared to last year."
