Final answer:
The motorcyclist should adopt the right tire track position when turning left from a passing lane into a passing lane.
Step-by-step explanation:
When a motorcyclist is turning left from a passing lane into a passing lane, they should adopt the right tire track position. This means that the motorcyclist should position their motorcycle in the right-hand side of the lane while making the turn. This position allows for better visibility and minimizes the risk of colliding with oncoming traffic.
