The Daily Advertiser has also obtained new figures that show speed was the most common factor in road deaths and injuries across the Wagga electorate for the past five years.

Mr Constance used the electorate as an example in Parliament after Wagga-based Nationals MLC Wes Fang criticised the move as "city-centric" via placing a bigger penalty burden on regional areas.

"I had a look at the stats for Wagga, where [Mr Fang] hails from. Wagga has had seven fatalities this year; way too many for one community," Mr Constance said.

Transport for NSW figures show that speeding was a factor in 43 per cent of road fatalities and 31 per cent of serious injuries across the Wagga electorate between 2015 and 2019.

The next most common factor was fatigue, present in 33 per cent of fatalities, followed by alcohol.

Wagga had 5.1 road deaths per 100,000 people compared to the 4.6 NSW average.

Mr Fang said the problem with removing warning signs was that it would not change behaviour at the time of offending.

"The practical reality of it ... is when a driver sees [a] speed camera sign, they either slow down or check their speed," he said.

"That act slows drivers down. If they don't slow down then they receive a fine, but they are given the warning to correct their behaviour and it's the behaviour that we want to correct.

"When drivers get a fine in the mail two or three weeks later, their behaviour at the time hasn't been corrected."

Mr Fang's argument that a time lapse before a fine undermined efforts to stop speeding has been supported by Wagga driving instructor Glen Gaudron.

Peter Frazer, whose daughter Sarah was killed in 2012 by a truck on the Hume Highway as she travelled to Wagga, said the electorate's road trauma from speeding was "terrible".

"We are talking about people travelling at high speed and not looking out for others. I am absolutely in favour of the removal of warning signs ... NSW is the only jurisdiction with those signs," he said.

Mr Constance also told The Daily Advertiser that speeding was "killing too many people".

"Two-thirds of all fatalities are in the country, in areas like Wagga, where too many people aren't getting home to their loved ones at night because of road trauma," he said.

"The removal of these signs could actually end up saving your life, or the life of someone you love."
