When approaching an intersection without a stop sign or traffic signal, who must you yield to?

Answer: B — Vehicles coming from the right

When approaching an intersection without a stop sign or traffic signal, the rule of yielding to vehicles coming from the right is based on standard right-of-way laws. In most jurisdictions, including Nevada, when you reach an intersection where there are no traffic controls, the general principle is to yield to vehicles that are already in the intersection or those that are approaching from your right. This ensures safety and helps to prevent accidents in situations where there might not be clear traffic direction. Though other vehicles, such as those from the left, may also be present, the specific rule is to prioritize the right-side traffic. Additionally, while pedestrians should always be respected and given the right-of-way, the question specifically seeks guidance on yielding to vehicles. Therefore, focusing on vehicles coming from the right is the key point in this scenario.
