Final answer:
d.Vehicles coming from the right
At an uncontrolled intersection, the right-of-way usually belongs to vehicles on the right. Drivers should still exercise caution and yield when necessary to maintain safety.
Step-by-step explanation:
When approaching an intersection without signs or lights, the right-of-way typically belongs to vehicles coming from the right. This general rule is applied to promote safety and reduce the chances of collision. However, all drivers should exercise caution and be prepared to yield if it's necessary to avoid an accident or ensure overall safety on the road, regardless of the right-of-way rules. It's important to note that while one vehicle may have the right-of-way, it's always crucial to observe the actual traffic conditions and proceed only when it's safe to do so.
