REVEALED: The little-known traffic light system that has left Sydneysiders stunned and changed the way they drive FOREVER
- TikTok users stuns Sydney drivers with little known traffic light system fact
- The TikToker penned the catchy jingle revealing sensors detect cars on the road
- Song shows users the best way to make traffic lights turn green at intersections
- Social media users were left stunned when they found out little known fact
Sydney drivers have been left stunned after discovering a little known traffic light trick.
In a video uploaded to TikTok by Bennymofodavis on Friday, it was revealed Sydney traffic lights change colour because a sensor beneath the road detects the vehicle.
‘Hey drivers on the road, these lines that you can see, are electro-magnetic sensors apparently,’ the video begins.
A TikTok user has pointed out sensors lie beneath the road at traffic light intersections in a viral catchy tune
‘And when you stop on them, that’s how the lights know.
‘To turn from red to green and let the cars go.’
The video not only amused social media users but shocked Sydney drivers who weren’t aware of how the traffic light system operates.
‘Aussie girl here, fully licensed for 10 years and never knew how the traffic lights worked just figured they were timed,’ one user wrote.
‘To be fair I’ve never been advised of this until now,’ commented another.
‘This should be an announcement for Transport NSW,’ suggested a third.
The TikTok user penned the song as a personal service announcement for drivers who stop a bit too far behind the line causing motorists to waste time and fuel.
The sensors detect the weight of the car prompting the traffic light to change from red to green
As the video pointed out NSW roads use the Sydney Coordinated Adaptive Traffic System (SCATS) to optimise traffic flow.
Inductive loop detectors are buried beneath the road surface to detect the presence of vehicles at most intersections across Australia.
The positioning of a vehicle is key to getting a red light to change to green in the quickest time possible.
A car usually needs to be stopped directly behind the white line of an intersection to be over the loop and be detected.
