Abstract

A safety sign and methods are shown for use on an oversized load with advantages such as being more visible in poor conditions such as snow, dust, fog, low light, etc. Safety signs as shown can be seen from farther away than conventional signs. Safety signs as shown eliminate problems associated with point source lighting.
