Is it legal to change lanes while approaching or going through an intersection?

Changing lanes while approaching or going through an intersection can be legal under specific circumstances, making the answer that states it is allowed if there are no vehicles in the lane accurate. This means that if you have ensured that the lane you intend to move into is clear of other vehicles, it is permissible to change lanes as long as it can be done safely without disrupting the flow of traffic or endangering other road users.

This flexibility allows for safer maneuvering around obstacles or positioning oneself for a turn. However, safety is crucial, and one must always exercise caution to avoid collisions or accidents.

Other options imply absolute rules that do not account for situational awareness, such as the claim that it is legal under any circumstances, which does not consider the potential dangers of doing so in traffic. Similarly, stating that it is never legal disregards instances where changing lanes might be necessary for safe navigation through the intersection. Lastly, while signaling is a critical aspect of safe lane changes, the legality of the action is also dependent on the conditions of the road and surrounding vehicles, making the option suggesting signaling alone insufficient.
