On a two-lane road, where is overtaking allowed?

Overtaking is typically allowed in the left lane on a two-lane road because this aligns with general driving regulations in many jurisdictions where the left lane is designated as the passing lane. This allows drivers to safely pass slower-moving vehicles without interfering with the flow of traffic traveling in the same direction.

When a driver wants to overtake another vehicle, it is essential for them to signal their intentions and ensure the left lane is clear to perform the maneuver. The design of roadways generally supports this model, whereby the left lane serves as an overtaking lane, allowing for a smoother traffic flow.

While the other options suggest various lanes or conditions under which overtaking could occur, they either introduce uncertainty or go against the conventional rules of the road that specifically designate the left lane for overtaking. Thus, understanding this principle is crucial for safe driving practices and effective navigation of two-lane roads.
