What traffic rule applies at unmarked intersections?

At unmarked intersections, the 'right-before-left' rule is the guiding principle for determining who has the right of way. This means that when two vehicles approach the intersection from different roads, the vehicle coming from the right has the right of way over the vehicle coming from the left. This rule is designed to promote orderly traffic flow and reduce confusion where there are no signs or signals to indicate traffic control.

Understanding this rule is particularly important in many European countries, where unmarked intersections are common, and drivers must rely on mutual awareness and courtesy. By adhering to the 'right-before-left' rule, drivers can help prevent accidents and ensure a smoother transition through intersections.

Other options may refer to various traffic rules or strategies, but they do not specifically apply to unmarked intersections in the context of right-of-way determination, making the 'right-before-left' rule the most relevant and correct choice in this scenario.
