The other day I was discussing some road safety issues and a treatment with the name of “Dragon’s teeth” was mentioned. To tell you the truth it was the first time that I heard of the term so I asked myself “What are Dragon’s teeth?”
By the term Dragon’s teeth in traffic management we mean one of the following three things:
- Triangular road markings that have been installed at the entry points to all 10,000 school zones across New South Wales up to 32.5 metres at the start of each school zone, to improve road safety for students. The Dragon’s Teeth markings further increase the visibility of school zones for motorists and provide a constant reinforcement to keep to the 40 km/h speed limit around schools.
- Calibrated edge and centre line markings used as a secondary method to check vehicle's speed manually by calculating its speed between them when using a road side speed camera.
- Road surface mechanical devices used to enforce one way traffic. They are mostly used on private road.
