Types of Street Lines
Street lines can be broadly categorized into several types, each serving a specific purpose. Understanding these categories is essential to grasping the overall significance of street lines.
Center Lines
Center lines, also known as median lines, are the lines that divide the road into two separate lanes. They can be solid, dashed, or a combination of both. The primary function of center lines is to separate opposing streams of traffic and prevent head-on collisions.
Solid Center Lines
Solid center lines indicate that passing is not allowed from either direction. They are often used on roads with heavy traffic, narrow lanes, or hazardous conditions.
Dashed Center Lines
Dashed center lines, on the other hand, indicate that passing is allowed from either direction. However, drivers should exercise caution when passing, as the dashed lines do not guarantee a safe passing zone.
Edge Lines
Edge lines are the lines that mark the edge of the road or the boundary between the road and the shoulder. They can be solid or dashed and serve as a visual guide for drivers to stay within their lane.
Solid Edge Lines
Solid edge lines indicate that the edge of the road is not to be crossed. They are often used on roads with a hard shoulder or a drop-off.
Dashed Edge Lines
Dashed edge lines, on the other hand, indicate that the edge of the road can be crossed, but with caution. They are often used on roads with a soft shoulder or a bike lane.
Other Types of Street Lines
In addition to center lines and edge lines, there are several other types of street lines that serve specific purposes.
Stop Lines
Stop lines are the lines that indicate where drivers should stop at an intersection or a stop sign. They are usually white and are accompanied by a stop sign or a red light.
Crosswalk Lines
Crosswalk lines are the lines that mark the area where pedestrians can cross the road. They are usually white and are accompanied by a pedestrian crossing sign.
Turn Lines
Turn lines are the lines that indicate where drivers can turn. They are usually arrows or curved lines that guide drivers through the turning process.
Bike Lane Lines
Bike lane lines are the lines that mark the area designated for cyclists. They are usually white and are accompanied by a bike lane sign.
