As part of our Ask 2 series, the newsroom will answer your questions about all things Houston. Question: What happens when two cars come to a four-way stop at the same time? Answer: If two vehicles come to a stop at a four-way stop, at the same time and are side-by-side, the right-of-way goes to the person who is on the right. This is not an optional yield sign. The law states "the operator of a vehicle approaching an intersection with a stop sign shall stop."
