Some WARNING signs display images of the traffic barriers, warning motorists what will happen if they drive in the wrong direction.
Signs are typically 45cm wide, and 60cm high, and are generally six pounds. All are chemical- and weather-resistant, using Avery Dennison T-2500 Reflective material and OL-1000 laminate coating. They have a three-year warranty, and come in black, green, red, or white.
A two-inch diameter powder-coated steel pole may be used to post one sign or two (one on each side of the pole; this is helpful in cases where motorists traveling one way need to be warned against entering a lane, and motorists traveling the opposite way must be informed that the lane only serves as an exit.). The post includes a base and mounting hardware (four wedge bolts, lag bolts, or the like) for installing it on asphalt or concrete surfaces.
Posts are designed for a standard mounting height of five feet, with the top of the sign ending at seven feet.
