When traffic signs are absent, who has the right-of-way at intersections?

In the absence of traffic signs at intersections, the general rule is that the vehicle on the right has the right-of-way. This rule is designed to promote safety and reduce confusion among drivers. When two vehicles arrive at an intersection simultaneously, the driver of the vehicle on the right is given the priority to proceed. This guideline helps establish a clear protocol for drivers to follow when there are no traffic control devices present, thereby minimizing the risk of accidents.

The other choices may seem reasonable at first glance, but they do not reflect the established traffic laws. The vehicle on the left would not have priority over the vehicle on the right, and factors like the number of passengers or the size of the vehicle are not criteria for determining right-of-way. Thus, the regulation that the driver on the right has the right-of-way serves to create a standardized approach to navigating intersections safely in scenarios where formal traffic signs are not present.
