At an uncontrolled intersection of roads equal in width, every vehicle is proceeding straight, and no signs, signals, pedestrians, or special vehicles affect priority. Which national rules apply? Select all that apply.

الشرح

With roads equal in width and every vehicle proceeding straight, traffic already within the intersection has priority, and simultaneous arrivals are resolved in favor of the vehicle approaching from the right. A blanket rule that the larger vehicle or the vehicle from the left goes first has no basis in the stated national priority rule.
