At a four-way stop, the vehicle that may proceed first is generally the one that:
- AIs turning right
- BIs the largest
- CHas the loudest horn
- DArrived and stopped firstCorrect
Why: At a four-way stop each driver stops, and the vehicle that stopped first proceeds first; if two arrive together, the vehicle on the left yields to the one on its right. (K53 / National Road Traffic Act, intersections)
