In which lane position is it often safest to ride when passing parked cars?

When passing parked cars, riding in the left portion of the lane is often the safest choice. This position allows the motorcyclist to maintain a safe distance from the vehicles on the right, reducing the risk of being struck by doors opening unexpectedly or by pedestrians stepping out from between cars. Additionally, being towards the left portion of the lane provides better visibility of any potential hazards, such as vehicles that might be turning out of parking spaces or driveways.

Positioning in the left portion helps keep the motorcyclist in a more maneuverable position—a crucial factor considering the inherent instability when navigating within close proximity to other vehicles. This lane positioning can also enhance the motorcycle's visibility to other drivers, who may be more likely to check the left side for approaching vehicles rather than the right.

The other options may place the rider in closer proximity to parked cars, increasing the likelihood of encountering danger, such as opened doors or sudden movements by pedestrians. Additionally, riding too close to the right shoulder can make it more challenging to react to any unexpected situations that may arise.
