Your own warning on a diamond sign
Drivers read a yellow diamond as a warning before they read a single word. Add your own message, like SPEED BUMP, BLIND DRIVEWAY, or HIDDEN ENTRANCE, and the shape does the rest.
- Black lettering, with room for a small note like NEXT 500 FT under the warning
- Black border, like a road warning sign
Choosing a color
Yellow fits most hazards on a private road or lot. Orange signals work zones and temporary hazards. Fluorescent yellow-green is the color for schools, crosswalks, and playgrounds, and fluorescent pink marks incident and emergency areas.
Size and speed
On a driveway or in a parking lot, 18" or 24" is enough. Roads posted at 35 mph and up usually get 30" or 36", so the words are big enough to read in time.
