Mobile speed camera use on the rise

More than 830 motorists a day are being booked by mobile speed cameras, with the NSW state government collecting $8 million in fines in just seven months.

An increase in the number of mobile speed camera enforcement hours from 900 to 7000 hours a month has helped boost the government's coffers after it issued just 26,453 fines in the 2013-14 financial year, netting $4.9 million.

In the seven months to January this year, the NSW state government has already issued 40,912 fines and raised $8.3 million.

Public anger over the explosion in mobile speed camera fines can only be soothed by giving motorists better warning before they get busted, the NRMA says.

The $8.3 million cash bonanza for the government has sparked a five-fold increase in attacks on camera cars, with 82 instances so far this financial year of objects being thrown, verbal abuse and cars swerving towards operators.

The NRMA believes hidden signs that don't even display the speed limit, anonymous camera cars and little distance between sign and camera are fuelling the rage.

These measures that we are suggesting will make it fairer and should slow people down before they get fined

"There has been a seven-fold increase in enforcement hours for mobile speed cameras, which has given rise to a perception of unfairness among motorists," NRMA president Kyle Loades said.

"The NRMA is aiming to address those perceptions and help reinforce the message that mobile speed cameras are about road safety, not revenue.

"These measures that we are suggesting will make it fairer and should slow people down before they get fined."

The plan involves displaying speed limits on mobile speed camera signs, greater distance between the signs and the cameras, and high-visibility markings on camera vehicles.

The organisation, which represents 2.4 million motorists, also wants the government to conduct a yearly audit to guarantee the cameras are put only in proven black spots.

NSW Roads Minister Duncan Gay hinted the government may make some changes.

"We always welcome constructive dialogue and it's fantastic to see the NRMA put forward sensible safety recommendations, which I've asked our roads safety experts to look at."
