When is it legal to share a lane with a motorcycle?

Sharing a lane with a motorcycle is prohibited under the law. Motorcycles are entitled to their full lane just like any other vehicle, and the rider needs that space for safety and maneuverability. This restriction ensures that both motorcyclists and other drivers can operate their vehicles safely without risking accidents caused by squeezing into a shared space.

In heavy traffic, closely following a motorcycle can lead to collisions if either vehicle has to stop suddenly. When there are no other vehicles, it's still illegal because motorcycles must maintain their full lane to ensure they have enough space to maneuver or react to road hazards. Even if a motorcycle is signaling, it does not change the fact that they need their lane to maintain safe riding practices. Hence, the understanding is that motorcycle riders should not be forced to share a lane, which makes 'never' the correct response.
