What action should drivers take at an intersection with no signs or signals?

Answer: B — Yield to traffic on the right

When approaching an intersection that has no signs or signals, the proper action for drivers is to yield to traffic on the right. This traffic rule is based on the principle of right-of-way, which helps maintain order and safety on the roads. In the absence of clear traffic control devices, the driver should give way to vehicles approaching from the right, as this helps to prevent collisions and allows for a smoother flow of traffic. This practice is essential for safe driving, as it creates a predictable environment where drivers know they must yield when encountering other vehicles at such intersections. By following this rule, drivers can navigate intersections more safely and efficiently, reducing the risk of accidents. The other choices do not follow the proper traffic laws or safe driving practices at uncontrolled intersections, thereby increasing the likelihood of accidents or confusion among drivers.
