The Brady 57894 safety sign for vehicles moving 25 mph or slower is bright reflective orange with a red border, weighs 0.7 lb., and measures 14 x 16 inches (H x W) on a vinyl surface. (H is height, the vertical distance from lowest to highest point; W is width, the horizontal distance from left to right.) The safety sign is vinyl for oil resistance, and low moisture absorption. Brady 57894 safety signs are often used on farm, road construction, and maintenance vehicles to alert drivers to use caution around the slow-moving vehicle.
