Wagga resident Trevor Neander was one of 558 drivers across the city snapped and fined during May for exceeding the speed limit by 10 kilometres per hour or under.

During the same month in 2019 when drivers were shown warning signs ahead of mobile speed cameras, just 20 fines were handed out for the same offence.

Mr Neander, aged 80, was driving west on Fernleigh Road near the Rules Club when he received the first speed camera fine of his life of $123 for driving at 60 kilometres per hour in a 50 zone.

"There are three different speed limits off the same roundabout. It's not making anyone safer, It's just revenue raising," he said.

"This road shouldn't be 50 as it's a high volume road in an industrial area.

"The should put the warning signs back up. Other people I know have been fined and they say it's a trap."

Revenue NSW figures showed almost $89,300 in total fines across Wagga during May 2021 from fines for the lowest level of speeding offence.

NSW Labor opposition leader Chris Minns has called for the return of mobile camera warning signs.

"Warning signs change behaviour and get drivers to ease off the pedal and slow down," he said.

"The NSW government has worked out a way to slug families with hundreds of dollars for low-range speeding offences by hiding the cameras.This policy has made families and tradies poorer, but it hasn't made our roads safer."

Transport and Roads Minister Andrew Constance said all fines would go a road safety fund and speed was a contributing factor to a lower proportion of crashes.

"Studies have shown that going just 5 kilometres per hour over the speed limit in a 60 zone doubles your risk of being involved in a crash where at least one person is killed or injured," he said.

"That's why we're guided by the experts, not some politicians more interested in pandering to people speeding than keeping our community safe."
