When must drivers give a directional signal?

Drivers must give a directional signal when they are preparing to make a turn or change lanes, ensuring they communicate their intentions clearly to other road users. This signaling is a key component of safe driving practices, as it helps to prevent accidents by informing others of your planned movements. While option C may refer to specific vehicles, the principle of signaling applies broadly according to the traffic regulations that mandate the use of directional signals to enhance safety on the road.

Proper use of signals is not just a matter of legality, but also of responsibility, as it helps maintain the flow of traffic and can significantly reduce misunderstandings between drivers. Therefore, understanding when and where to use turn signals is essential for all drivers, regardless of the specific context provided in the options.
