Final answer:
When you plan on turning left at an intersection and a motorcycle is going straight, you must yield to the motorcycle since oncoming traffic has the right of way.
Step-by-step explanation:
In a scenario where you are planning to turn left and a motorcycle is approaching the intersection going straight, the general rule of the road is that the vehicle turning left must yield to oncoming traffic which has the right of way. In this case, you would need to yield to the motorcycle.
The responsibility to yield is typically dictated by traffic signs, road markings, and traffic laws which vary by jurisdiction but commonly favor vehicles traveling straight over those making turns.
