What are the black squiggly lines on many roads?

Answer 1

The black squiggly lines on many roads are typically made of a rubberized material used for road surface marking or as part of a traffic monitoring system. They are often installed to help detect vehicle speed and count traffic flow. These lines can also be used for lane marking or to indicate areas where vehicles should not park. Their primary purpose is to enhance safety and improve traffic management.

Answer 2

The black squiggly lines on many roads are known as "thermoplastic markings" or "road markings." They are made from a durable material that provides better visibility and traction for vehicles, especially in wet conditions. These markings often indicate lane boundaries, crosswalks, or other important traffic information. Their design helps improve road safety by guiding drivers and pedestrians effectively.
