Warning signs

                                              Warning signsSome of the first roadside signs —ancient milestones— merely gave distance measures. Hazard warnings were rare though occasional specimens appeared, such as the specific warning about horse-drawn vehicles backing up which was carved in stone in Lisbon's Alfama neighborhood in 1686. The early signs did not have high-contrast lettering and their messages might have been easily overlooked. Signs were written in the local language (example); symbolic signs, though long used on certain tradesmen's signs

Nowadays a traffic warning sign is a type of sign that indicates a hazard on the road that may no be readily apparent to a driver. In most countries, they usually take shepe of an equilateral triangle with a White background and a thick red border. However, both the color or the background and the color and thickness of the border varies from country to country.The signs can also mark school zones, warn drivers of people walking in the Street, indicate when a multilane highway is being narrowed, to warn of level crossings ahead, etc.

In Europe, the 1968 Vienna Convention on Road Signs and Signals (which became effective in 1978) tried, among other things, to standardize important signs. After the fall of the Iron Curtain and greater ease of country-to-country driving in the Eurozone, European countries moved toward lessening the regional differences in warning signs

Road Traffic Signs are not only important to new car drivers. It is also important at every citizen in the US know the important of traffic signs. Over the years of statistics, more and more people both on the road and off-road find these signs very important. This is why the U.S. Department of Transportation–Federal Highway Administration is strictly implementing these rules and regulations to avoid accidents on the road.The main reason why these signs are available on the road is because of SAFETY. Traffic signs make sure that all drivers are aware of the rules and the dangers on the road. Without these signs, accidents may occur more often. These signs also warn the drivers of the potential dangers that can be encountered on the roads
