When is it important to use the left turn signal while driving a bus?

Using the left turn signal while preparing to make a left turn is crucial for several reasons. First and foremost, signaling a left turn informs other drivers and pedestrians of your intent to change direction, which helps prevent accidents. When driving a large vehicle like a bus, the need for clear communication with other road users is amplified due to its size and slower maneuverability compared to passenger vehicles.

Additionally, turning left typically involves crossing oncoming traffic, making it essential for other drivers to be aware of your actions. By signaling in advance, you allow drivers behind you to prepare for your turn and alert those facing you that you will be crossing their path. This practice enhances overall road safety and promotes a smoother flow of traffic.

In contrast, signaling for other scenarios, such as a U-turn or lane change, serves different purposes and would not specifically require a left turn signal in the context of making a left turn.
