Four vehicles approach a four-way intersection controlled by stop signs in all directions. The vehicles stop at the intersection under the following conditions:
- Vehicle A comes to a complete stop first and intends to drive straight.
- Vehicle B and Vehicle C arrive and stop at the exact same time right after Vehicle A. Vehicle B is located to the right of Vehicle C.
- Vehicle D stops last after all other vehicles.
In what order should these vehicles be granted the right-of-way to proceed through the intersection?
- 1Vehicle A (arrived first at the intersection)
- 2Vehicle B (arrived second, positioned to Vehicle C's right)
- 3Vehicle C (arrived second, positioned to Vehicle B's left)
- 4Vehicle D (arrived last at the intersection)
Answer
The vehicles must be granted right-of-way in the order of Vehicle A first, followed by Vehicle B, then Vehicle C, and finally Vehicle D.
At a four-way stop, precedence is established first by arrival order: the first vehicle to complete its stop proceeds first (Vehicle A). When two drivers arrive and stop simultaneously, the driver on the left must yield to the driver on the right. Because Vehicle B is positioned to the right of Vehicle C, Vehicle B moves next, followed by Vehicle C. Vehicle D arrived last and must wait until all vehicles that stopped before it have cleared the intersection.
