Difficulty: EasyRight-of-Way Rules at Intersections

Three vehicles stop at a four-way stop intersection: Car A arrives and stops first. Car B and Car C arrive and stop simultaneously a few seconds later, with Car B positioned to the right of Car C. In what order should these vehicles proceed through the intersection?

  1. 1Car A (arrived first)
  2. 2Car B (arrived simultaneously with Car C, located to Car C's right)
  3. 3Car C (arrived simultaneously with Car B, located to Car B's left)

Answer

The vehicles must proceed through the intersection in the following order: Car A first, followed by Car B, and finally Car C.
Car A arrived first, giving it immediate right-of-way priority to proceed first. Car B and Car C arrived simultaneously after Car A. Under standard right-of-way rules for simultaneous arrival at a stop sign, the driver on the left must yield to the driver on the right. Because Car B is to the right of Car C, Car B proceeds second, leaving Car C to proceed last.

Step-by-Step Solution

1
Identify which vehicle established first priority by arrival time.
Car A arrived first and stopped before the other vehicles.
The standard rule at a multi-way stop is 'first to arrive, first to proceed.'
2
Determine right-of-way between Car B and Car C, who arrived at the exact same time.
Car B proceeds before Car C because Car B is positioned to the right of Car C.
When two vehicles arrive simultaneously at a stop sign, right-of-way is given to the vehicle on the right.
3
Combine the arrival order and right-hand priority to determine final sequence.
The correct order of movement is Car A, then Car B, then Car C.
Car A moves first based on arrival time, Car B moves second based on the right-hand rule, and Car C yields until Car B clears.
