When two vehicles enter an intersection from different highways at the same time and the official traffic control signals for the intersection are inoperative which driver has the right-of-way and wha?

When traffic control signals are inoperative, the right-of-way is generally determined by the rules of the road, which typically state that the driver on the right has the right-of-way. Therefore, if two vehicles enter an intersection simultaneously, the driver on the right should proceed first. Additionally, drivers should exercise caution and yield to any vehicle that is already in the intersection. It's always best for drivers to communicate and make safe decisions to avoid accidents.
