Direction, position, or indication sign

[3] However, it was not until the invention of the motor car at the turn of the 20th century that modern direction signs evolved, with fewer words and clear design allowing them to be read at speed.

However, as trading between towns and regions increased, milestones were found to be inconvenient for giving directions at crossroads.

Most early direction signs were based on the traditional styles in use in area; the United Kingdom used adapted, cast iron fingerposts for signing directions,[3] while the United States adopted an ad hoc scheme based on traditional trail markings.

The end of the war, on the other hand, presented itself as an opportunity, seized by many European nations, to set about redeveloping their directional signage systems.

The British Worboys Committee (established in 1963) went even further, creating signs with detailed diagrams of junction layouts.

Evacuation signs are common in areas where there is a high risk of dangers such as flash flooding, volcanic activity and lahar, tsunami, hurricane and storm surge.
