Difficulty: EasyRight-of-Way Rules at Intersections

Three vehicles arrive at a four-way intersection controlled by stop signs in all directions at different times: a red car arrives first, a blue truck arrives second, and a white van arrives third. None of the vehicles are turning. In what order should these vehicles be granted the right-of-way to proceed through the intersection?

  1. 1Red car
  2. 2Blue truck
  3. 3White van

Answer

The vehicles should proceed in order of arrival: first the red car, second the blue truck, and third the white van.
At a four-way stop, traffic rules specify a 'first-come, first-served' order. The vehicle that reaches the intersection and stops first has the right-of-way. Since the red car arrived first, it proceeds first; the blue truck arrived second, so it proceeds next; and the white van arrived last, so it proceeds final.

Step-by-Step Solution

1
Identify the intersection control rule
At an all-way stop intersection, the first-come, first-served rule applies.
Standard traffic regulations dictate that at a multi-way stop, right-of-way is granted to drivers in the exact order in which they reach the stop line and come to a complete stop.
2
Determine arrival order
The arrival order is: Red car (1st) -> Blue truck (2nd) -> White van (3rd).
The scenario explicitly specifies the sequential order of arrival for each vehicle.
3
Apply the right-of-way rule to establish movement sequence
The correct sequence of movement is Red car, followed by Blue truck, followed by White van.
Each vehicle proceeds in turn based on its established arrival position once the intersection is clear.
