What determines the priority road at an intersection?

The priority road at an intersection is determined by roadways that have clear markings such as a centerline or designated traffic lanes. These markings help indicate the intended direction of traffic flow, providing a visual cue for drivers. When roads are properly marked, it becomes easier for all road users to understand which way traffic should proceed, enhancing safety and reducing confusion at intersections.

In many traffic systems, a marked road typically takes precedence over unmarked roads, as the markings signify a level of importance or main thoroughfare designation. Therefore, vehicles on roadways with a centerline or traffic lane typically have the right of way in situations where they intersect with less clearly defined routes.

Other options like painted curbs, fire lanes, or lack of speed limit signs do not inherently convey priority or directionality in traffic management, making them less applicable as indicators for determining a priority road at an intersection.
