A NSW government proposal to remove signs from in front of mobile speed cameras has received a mixed response from Wagga road users.
Victoria's 31 per cent jump in road deaths this year, despite the state's hidden mobile speed cameras, has many sceptical of how effective the policy could be if enacted in NSW.
Wagga Able Driving School owner and instructor Glen Gaudron said speed cameras without warning signs would look more like a revenue raising effort than a safety measure.
"When you have speed cameras out, that does cause people to slow down when they see those signs, so they are having an effect in that way," he said.
"If they remove those signs, people are going to speed more and it's just going to be a revenue raising thing for the government; that's what they are looking at, in my opinion."
Mr Gaudron said "a lot" of drivers would still speed even if there was a risk of hidden speed cameras and he said retesting young drivers after they had spent time on the P-plates would yield better safety results.
Wagga recreational cyclist Emilie Graham said she hoped hidden speed cameras would encourage safer driving but the lack of evidence from Victoria's approach was a concern.
"When you are handling a lethal weapon, which is what a car is, it's in everyone's interest that you drive safely and if this goes some way to encourage better behaviour, I say let's try it," she said.
"I do take the point that the timing of the fines in relation to the timing of the infringement is too remote.
"Perhaps to go hand-in-hand with this would be fines that are closer to the time of the infringement."
NSW Transport Minister Andrew Constance has said the government would consider the removal of speed camera warning signs and referred to expert evidence which claimed 54 lives a year could be saved without signs.
The proposal is based on a Auditor General's report into mobile speed cameras from late last year that found "government decisions to limit its hours of operation and use multiple warning signs" had worked to "limit the ability of the mobile speed camera (MSC) program to effectively deliver a broad general network deterrence from speeding".
The report also argued that placing and removing the signs created additional costs and exposed workers to increased risk of being hit by a vehicle.
NRMA spokesman Peter Khoury said the motorist group wanted the signs to stay and having more police on patrol would help road safety.
"The signs are an important education tool as they are set up in places where people have previously been killed or injured," he said.
