Show Uniform Signs Make for Higkway Safety An important step to promote highway high-way safety was recently taken by the United States bureau of public roads in co-operation with the state highway high-way departments, in adopting uniform standards for warning signs to be used throughout the country.

Hazards will be indicated by signs which will be uniform in all sinks and which will plainly indicate the kind and degree of danger. The new signs make use of a system sys-tem of different shapes, thereby increasing in-creasing their value at night.

Twenty states are now actually engaged in creeling these standard warning signs, and oilier states have signified their intention of doing the same. Scientific Scien-tific American. |
