At an uncontrolled intersection (no stop signs, yield signs, or traffic lights), the general rules of right-of-way apply. The basic rule is: the vehicle on the right has the right-of-way if two or more vehicles arrive at the intersection at the same time. In practical terms, if you and another vehicle reach an intersection simultaneously, you must yield to the car on your right. If you are the car on the right, then you have the right-of-way (provided the other drivers also honor the rule). If three or four cars all roll up at the same time (which can be confusing), you still yield to any vehicle to your right.
Another key point: any vehicle already in the intersection has the right-of-way over a vehicle just approaching it. And if two vehicles arrive at slightly different times, the one that arrived first goes first (first come, first go).
For example, imagine a simple intersection of two roads crossing and no one has a stop sign. If you approach and another car is coming from your left at about the same time, you are to their right, so you get to go first (assuming you truly arrived at the same time). If the other car clearly got there before you, then they proceed first. If you got there first, you go first. If you and another driver directly across from you arrive at the same time and one of you is going straight while the other wants to turn left, the one going straight generally has right-of-way (since the left-turner must yield to oncoming traffic).
Because these situations can be tricky, always approach uncontrolled intersections with caution. Make eye contact with the other driver if possible, and proceed slowly. If in doubt, it’s safest to yield rather than force the issue. But by law, when simultaneous arrival happens, yield to the car on your right.
