Intersections and turns1 of 3
Two vehicles reach an intersection at about the same time. What must the driver on the left do?
The answer
Answer: D. When two vehicles arrive at an intersection at about the same time, both must stop, and the driver on the left must yield the right-of-way to the driver on the right. The law does not actually give the right-of-way to anyone; it states who must yield, and no one may take it if a crash may result.
