Frequently asked questions
Is this sign legally required on Australian roads?
It's not universally mandated, but road authorities widely install it on multi-lane roads to reinforce safe overtaking practice and reduce collision risk.
What's the difference between the two sizes?
450×600 mm suits local roads and urban arterials; 600×800 mm is better for highways where drivers need to read the sign from higher speeds.
How often does reflective sheeting need replacing?
Reflective grades provide different visibility performance. Choose the grade required by the project specification and site conditions, and confirm any road, traffic or high-risk requirement with the relevant authority before ordering.
Can I mix sizes in one order?
Yes, you can order both sizes together at no extra charge. This is useful for staggering signs across longer road sections.
What's the typical cost for a council ordering 20+ signs?
