Supplemental Sign Placards FAQ
What is a supplemental sign placard?
A supplemental sign placard is a smaller sign mounted directly below a primary traffic sign to add information such as a distance, direction, or condition. It supplements the sign above it and is not used on its own.
How do supplemental placards mount?
They install on the same post immediately beneath the primary sign, so both are read together. They share the post and are sized to match the sign above.
What kinds of supplemental placards are there?
Common types include distance plaques (500 Ft, 2 Miles, Next 500 Ft), Ahead plaques, directional arrow plaques, advance street name plaques, Photo Enforced, When Flashing, New, and Notice plaques.
What color are supplemental placards?
The placard color matches the sign it supports - yellow for warning signs, white for regulatory signs - so the pair reads as one message.
Can supplemental placards be customized, and what are they made of?
Yes - distances, street names, arrow direction, and wording can be customized. Placards are printed on rust-proof .080-inch aluminum with reflective sheeting to match the primary sign.
