What is the correct way to signal a lane change?

The correct method for signaling a lane change is to use turn signals and check mirrors and blind spots. This practice is crucial for ensuring your safety as well as the safety of other road users. By using turn signals, you communicate your intention to other drivers, allowing them to anticipate your movements. Checking mirrors ensures that you are aware of vehicles to your side and rear, while inspecting blind spots helps identify any vehicles that might not be visible in your mirrors. This comprehensive approach promotes safer driving and reduces the risk of collisions during lane changes.

The other methods mentioned are not safe practices for signaling a lane change. Relying only on hand signals is insufficient in modern traffic, where vehicles often have closed windows and sound barriers that limit the effectiveness of non-verbal communication. Changing lanes quickly without proper signaling can lead to dangerous situations, as it may startle other drivers and lead to accidents. Lastly, honking your horn as a warning does not provide the same clear indication of intent as turn signals and can be misinterpreted, contributing to confusion on the road.
