In which three situations may you overtake another vehicle on the inside or left?

Overtaking another vehicle on the inside or left is generally permissible under certain conditions to maintain the flow of traffic and ensure safety. In the context of traffic rules in Malta, one of the scenarios where this is acceptable is when traffic is moving slowly in the right-hand lane.

When traffic in the right lane is slow-moving or congested, and you find that there's a clear path on the left, overtaking on the inside can help you avoid unnecessary delays and keep traffic moving. This can be particularly important in situations where the left lane is open, and the right lane is heavily congested, allowing for a safer and more efficient use of the road space.

In other scenarios, such as when a vehicle is preparing to turn left or when driving in a tunnel, specific rules and safety considerations might restrict such maneuvers. In a one-way street, while overtaking may seem more straightforward, it is crucial to ensure that it does not pose a risk to pedestrians or other road users. Hence, overtaking on the inside is most clearly applicable and accepted when traffic conditions in the right lane necessitate it.
