What should you do before changing lanes?

Before changing lanes, it is essential to check your mirrors and blind spots. This step is crucial for ensuring the safety of all road users. By checking your mirrors, you can see the vehicles directly behind and alongside you, allowing you to gauge the distance and speed of other drivers. Blind spots are areas that are not visible in your mirrors, and vehicles can be present in these spaces without your knowledge. Looking over your shoulder to check blind spots helps to ensure that no vehicle is attempting to occupy the lane you intend to switch into.

Engaging in this practice reduces the likelihood of collisions and facilitates safer lane changes. It also promotes defensive driving by making you aware of your surroundings, which is vital for making informed decisions while driving.
