I think you've misunderstood me. I was responding specifically to the case pointed out by the OP in which 2 cars get to a stop sign at the same time. Here's the relevant CA code, and I haven't heard of a state that does it differently: 21800. (a) The driver of a vehicle approaching an intersection shall yield the right-of-way to any vehicle which has entered the intersection from a different highway. (b) (1) When two vehicles enter an intersection from different highways at the same time, the driver of the vehicle on the left shall yield the right-of-way to the vehicle on his or her immediate right, except that the driver of any vehicle on a terminating highway shall yield the right-of-way to any vehicle on the intersecting continuing highway. http://law.onecle.com/california/vehicle/21800.html http://law.onecle.com/california/vehicle/21800.html
