A cross, or intersection, is a point where two or more roads meet. These areas are crucial for traffic flow, allowing vehicles and pedestrians to change directions. Intersections can vary in complexity, from simple two-way stops to multi-lane roundabouts, each designed to manage the movement of traffic safely. Traffic signals, signs, and road markings are often used at intersections to guide drivers and pedestrians. Properly designed intersections help reduce accidents and improve overall road safety. Understanding how to navigate these areas is essential for all road users, including drivers, cyclists, and pedestrians.
