About this product

Warning & Diamond Signs

The diamond is read before it is read. Drivers process the shape and the yellow long before they resolve the symbol inside it, which is why a warning message on a rectangle does not work nearly as well as the same message on a diamond.

Standard symbols cover most needs — curve, crossing, signal ahead, speed hump, dead end — and we hold the artwork for all of them. Custom symbols and legends are straightforward on private sites, and we will draw the symbol properly rather than shrinking a logo into the space.

Where conspicuity really matters, fluorescent yellow-green sheeting is measurably better than standard yellow in dawn, dusk and rain. It is the specification for pedestrian and school crossings, and it costs little more.

Sites with real hazards should not be relying on a laminated notice. Send your symbol and quantity for a free mockup and quote on custom warning signs today.

FAQ

Warning & Diamond Signs: quick answers

What is the minimum order for warning signs?

Minimum order is just 12 — with bulk pricing tiers as quantities grow.

How fast will my order arrive?

Your free mockup lands within 24 hours and the finished order ships in about 2 weeks — express turnaround is available for tight dates.

What is fluorescent yellow-green for?

Pedestrian, school and bicycle crossings. The pigment fluoresces under the blue-rich light of dawn, dusk and overcast rain, so it reads noticeably earlier than standard yellow in exactly the conditions where those crossings are most dangerous.

Can you make a symbol that does not exist?

Yes, for private sites. We draw it in the standard visual language — heavy strokes, no fine detail, high contrast — rather than dropping in an illustration, because a symbol has to be legible at speed.
