J. YIELDING RIGHT-OF-WAY
Right-of-way rules tell you and other drivers what to do. These rules say who has right-of-way
when two (2) or more streets come together. They also cover different situations.
Never think that you have the right of way. Always look at the situation and think about safety.
Yield the right-of-way to:
 A driver who is at the intersection before you.
 Drivers in the opposite lane when you are making a left turn.
 The driver on your right at a four-way stop if both of you arrive at the same time.
 Drivers on a public road if you are coming from a driveway or a private road.
 Drivers already on an interstate highway if you are on the entrance ramp.
 Pedestrians, bicyclists, and others that are still in the intersection.
Remember, courtesy is the key.

So. . .that is clear as mud.
