Intersections and turns1 of 2
At an all-way stop intersection in Massachusetts, if two vehicles arrive at the exact same moment, who has the right-of-way?
The answer
Answer: C. Under Massachusetts right-of-way rules, at an all-way stop where two vehicles arrive and stop simultaneously, the driver on the right has the right-of-way. If vehicles arrive at different times, the first vehicle to come to a complete stop has priority to proceed across the intersection.
