Four vehicles arrive at a four-way uncontrolled intersection under different scenarios. Arrange the vehicles in the correct order of right-of-way precedence from first to yield to last to yield (first to proceed to last to proceed).
- 1An emergency vehicle with active siren and flashing lights proceeding straight through the intersection
- 2A vehicle already established inside the intersection turning left
- 3A vehicle positioned on the right of another vehicle arriving simultaneously at an uncontrolled four-way stop
- 4A vehicle turning left facing oncoming straight-through traffic at an uncontrolled intersection
Answer
The correct order of proceeding through the intersection is: (1) Emergency vehicle with lights and siren, (2) Vehicle already established inside the intersection, (3) Vehicle on the right arriving simultaneously, and (4) Vehicle making an unprotected left turn facing oncoming traffic.
Right-of-way order follows a clear statutory hierarchy: active emergency vehicles take highest priority, followed by vehicles already clearing an intersection, then vehicles applying the yield-to-right rule for simultaneous arrival, and finally vehicles making unprotected left turns which must yield to through traffic.
