In terms of lane usage, what is critical when turning at an intersection?

Answer: C — Be in the proper lane prior to the turn

The importance of being in the proper lane prior to making a turn at an intersection lies in ensuring safety and maintaining the flow of traffic. When approaching an intersection, drivers must be aware of which lanes are designated for turning and which are for going straight. Using the correct lane for a turn minimizes the risk of collisions with vehicles that are continuing straight or making different types of turns. Being in the proper lane allows for a smoother transition into the desired lane after the turn and helps avoid sudden lane changes which can create confusion and lead to accidents. It also allows other drivers and pedestrians to anticipate your actions, contributing to overall road safety. Therefore, it's crucial for drivers to navigate to the appropriate lane well in advance of making a turn.
