How to know who gets to go -- who has the right of way when driving

One of the most common places for a crash to happen is an intersection. Usually someone fails to yield the right of way to someone else. There are established rules for who is to yield to whom in specific situations.

At intersections controlled by signs or signals you must obey the signs or signals. At intersections not controlled by signs or signals, you should yield to the vehicle already at the intersection. If two vehicles approach the intersection at the same time then yield to the vehicle on your right.    

If a two lane road intersects with a road of three or more lanes the driver on the road with one or two lanes must yield to the driver on the road with more lanes. At a T intersection the driver on the through street has the right of way. When an access road meets a highway exit ramp the driver on the access road must yield to drivers exiting the highway.
