Frequently asked
How do I specify the distance on the sign?
Provide the distance (in km) when placing your order. Our production team will print it into the blank field. Common distances are 2, 5, and 10 km; we can accommodate other values.
Why is a distance warning important for winding roads?
Drivers need advance notice to adjust speed before entering curves. A distance field gives them time to brake gradually, reducing accident risk on hazardous sections.
Can I order multiple signs with different distances?
Yes, you can mix distances in a single order. Specify each distance requirement, and we'll produce them accordingly.
What reflectivity level is recommended for mountain roads?
Class 1 reflective is standard and suitable for most roads. For high-speed highways with heavy night traffic, consider Class 2 reflective (available on request) for enhanced visibility.
How long does production take for custom distances?
Standard custom orders are ready within 5–7 business days. Rush options are available; contact us for expedited timelines and any additional costs.
