If you are on a two-way road and the vehicle ahead is turning left into a driveway, when may you pass it on the right?

Passing a vehicle that is turning left into a driveway on a two-way road is permitted when there is enough space on the right side of the vehicle, such as a designated lane or a wide shoulder. This maneuver is allowed as long as doing so is safe and does not interfere with the vehicle's turn or any pedestrians that may be present.

Having sufficient space between the curb and the turning vehicle is essential because it ensures that you can safely maneuver without running the risk of a collision or causing a hazard to other road users. This situation takes into account the flow of traffic and the proper use of available road markings or lanes, which is why this choice is the correct one.

Other options do not provide the necessary context or conditions for safe passing. The choice that suggests to pass "whenever you feel it's safe" is too subjective and does not align with traffic laws. Another option that allows passing only if there are no pedestrians present overlooks the importance of considering the road situation, which may allow safe passage even with pedestrians nearby if there is adequate space. Lastly, stating that passing is never allowed in this situation is overly restrictive and not true, as long as the conditions are met for a safe maneuver.
