In most instances a lane of travel will be marked as the lane that is merging with the other lane or lanes. If so, the lane that is NOT ending has the right of way. When entering a freeway or Interstate roadway, the traffic already on the main lanes of travel has the right of way and the entering traffic has the duty to "merge" safely with the traffic already flowing on the main lanes.
It is generally accepted practice for all traffic (pedestrian, bicycle, skate, equine) to all move in the same direction with each giving warning to the other in an overtaking situation.
