Is it necessary to use directional signals while passing on the expressway?

Using directional signals while passing on the expressway is necessary to indicate a change of lanes. This practice is crucial for maintaining safety and communication among drivers. When a driver intends to change lanes, using a directional signal alerts other road users of their intention to move to another lane, which can help prevent collisions. It informs drivers behind and adjacent to them about their plans, allowing for a more organized flow of traffic.

By signaling, drivers demonstrate good driving etiquette and responsibility, which promotes safer driving conditions for everyone. Ensuring clarity in lane changes is especially important on expressways where speeds are higher and reaction times are limited. Therefore, the use of directional signals is a fundamental aspect of safe driving practices in this context.
