If a vehicle is making a left turn, where can you legally pass them?

When a vehicle is making a left turn, passing on the right can be legal, provided it is safe to do so. This generally applies in situations such as when there is sufficient road space, and the left-turning vehicle is signaling their intention to turn. In many jurisdictions, passing on the right is allowed when the left lane is occupied or being used properly by another vehicle making a left turn, as long as it is done with caution and without violating traffic laws.

This option recognizes that there are specific circumstances on the road where passing can be executed safely and legally, such as in scenarios involving multiple lanes or when there are specific road markings indicating that it is permissible to pass in that manner.

Other choices may suggest restrictions or alternatives that do not take into account the specific scenario of passing a vehicle turning left safely and legally, which is why option B is the appropriate choice in this context.
