Difficulty: HardRight-of-Way Rules at Intersections

Four vehicles arrive at an intersection controlled by four-way stop signs under different timing and directional conditions. Based on standard DMV right-of-way rules, arrange the vehicles in the correct sequential order in which they should proceed through the intersection.

  1. 1Vehicle 1 (facing North): Brought to a complete stop at the stop line before any other vehicle arrived at the intersection.
  2. 2Vehicle 2 (facing East): Stopped simultaneously with Vehicle 3, intending to proceed straight through the intersection.
  3. 3Vehicle 3 (facing West): Stopped simultaneously with Vehicle 2, intending to make a left turn across Eastbound lanes.
  4. 4Vehicle 4 (facing South): Stopped at the intersection last, after Vehicles 1, 2, and 3 were already at a complete stop.

Answer

The correct order of movement through the intersection is: Vehicle 1 (facing North), followed by Vehicle 2 (facing East), then Vehicle 3 (facing West), and finally Vehicle 4 (facing South).
Right-of-way at a four-way stop follows two key principles: 1) First vehicle to stop has initial priority (Vehicle 1). 2) When opposing drivers arrive simultaneously, straight traffic (Vehicle 2) takes precedence over left-turning traffic (Vehicle 3). Finally, any vehicle arriving last (Vehicle 4) must wait for all prior arrivals to clear.

Step-by-Step Solution

1
Determine initial arrival priority.
Vehicle 1 (facing North) proceeds first.
At a four-way stop, right-of-way priority is determined primarily by arrival time; the first vehicle to come to a complete stop goes first.
2
Evaluate conflict between simultaneous arrivals.
Vehicle 2 (facing East) proceeds second.
When opposing vehicles stop at the exact same time, traffic moving straight has right-of-way over traffic making a left turn across the path of travel.
3
Assign sequence to the remaining simultaneous arrival vehicle.
Vehicle 3 (facing West) proceeds third.
Vehicle 3 must yield to oncoming straight traffic (Vehicle 2) first, but retains priority over vehicles that stopped after it.
4
Assign final position based on latest arrival time.
Vehicle 4 (facing South) proceeds fourth.
Vehicle 4 arrived at the intersection after all three other vehicles had already stopped, requiring it to wait until prior arrivals have cleared.
