Frequently asked questions
Is this sign required by law on steep roads?
While not universally mandatory, AS 1319 and state transport authorities recommend low-gear warning signs on sustained downhill sections exceeding 6% gradient to prevent brake failure.
What size is suitable for a steep mountain pass?
Available sizes are 450 x 600mm (Large), 600 x 800mm. Viewing-distance notes are a practical selection aid, not a substitute for checking the approach distance, lighting, mounting position, wording and site risk assessment.
How durable is the reflective coating?
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 order signs for multiple locations?
Yes, we provide bulk discounts for operators installing signs across multiple sites. Contact sales with your location list for a volume quote.
What mounting options do you recommend?
Signs are supplied flat; mounting hardware and methods should comply with AS 1319 and local road authority guidelines for your installation height and angle.
