Side-by-Side White Lines
Side-by-side white lines are a type of traffic control device used to separate lanes of traffic. They are typically used on highways and other high-speed roads to help drivers stay in their lanes and reduce the risk of accidents. The lines are usually painted in a bright white color and are typically spaced at least three feet apart. Side-by-side white lines are also used to indicate the boundaries of parking spaces, crosswalks, and other areas.
History of Side-by-Side White Lines
The use of side-by-side white lines to separate lanes of traffic dates back to the early 20th century. In the United States, the first use of the lines was in the 1920s, when they were used to separate lanes of traffic on the Lincoln Highway, the first transcontinental highway in the country. The lines were initially painted in a yellow color, but were later changed to white in order to make them more visible to drivers. Since then, side-by-side white lines have become a common sight on roads throughout the United States and other countries.
