At an open intersection, the right-of-way is given to the vehicle on your right if you both arrive at the same time. This rule helps manage traffic flow and avoids confusion by providing a clear guideline on who should go first. Yielding to the right-hand driver ensures smoother movement through intersections, reducing the risk of collisions and promoting safer driving practices. By adhering to this rule, drivers demonstrate awareness and respect for traffic protocols, contributing to orderly vehicular interactions.
