Point-to-point speed cameras are a feature of back country roads. Also known as average speed cameras, they are placed at either end of a section of road, and calculate the average speed of vehicles travelling between two or more points along a section of road.

In NSW these cameras have been used only to monitor the speed of heavy vehicles speed over a set distance.

But a recent announcement by the NSW Roads Minister John Graham will see a trial rolled out along two stretches of NSW highways and will target all road users, including light vehicles.

The trial will be conducted on two roads - the Hume Highway between Coolac and Gundagai (16km between cameras) and the Pacific Highway between Kew and Lake Innes, Port Macquarie (15km).

The state government announced on September 8 that NSW would join other states in using average speed cameras for light vehicles to help combat the rising road toll, which stands at 227 - two more than at the same date in 2023.

"NSW is the only jurisdiction in the world to use average speed cameras but restrict their use to heavy vehicles only," Minister Graham said.

"In the context of a rising road toll, now is the time to trial these cameras for light vehicles and understand if we can keep more people safe on the road more of the time."

Minister Graham also reportedly said the cameras were "a truer reflection of how quickly people are driving" given they test a vehicle's speed over 15 or 16km rather than at a singular moment, meaning motorists can't simply temporarily slow down to avoid them.

The trial will run for six months, but for the first 60 days, motorists will receive a warning letter in lieu of a fine or demerit points.

In-road sensors will capture a vehicle passing through a section of road, while cameras captures their speed and takes a time-stamped digital image of the vehicle.
