What should you do if you need to change lanes while driving?

When you need to change lanes while driving, the most appropriate action is to check your mirrors and signal your intent. This practice is essential for safe driving because it ensures that you are aware of your surroundings and that other drivers are informed of your intentions. By checking your mirrors, you can assess the traffic around you and identify any potential hazards. Signaling not only communicates to other road users that you plan to change lanes, but it also helps prevent accidents by giving them time to react.

Using your horn before changing lanes is not advisable, as this could startle other drivers and may not effectively communicate your intentions. Simply making a lane change without signaling is unsafe and against traffic regulations, as it can lead to collisions or misunderstandings with other drivers. Checking only your blind spot, while important, should not be done in isolation; it should accompany the use of mirrors and signaling to ensure a comprehensive assessment of the road. Engaging in all these actions collectively promotes safety and responsible driving practices.
