What should you always do before making a lane change?

Before making a lane change, it's essential to check your mirrors and blind spots to ensure that the lane is clear and safe for you to move into. This practice allows you to observe other vehicles that may not be visible in your mirrors, particularly those that are in adjacent lanes or in your blind spots.

By thoroughly checking your surroundings, you can avoid collisions and ensure that you are making a well-informed decision while driving. This step is crucial for maintaining safety on the road, as it helps you assess not only the immediate space around your vehicle but also the behavior of other drivers.

In addition to checking your mirrors and blind spots, signaling your intent is also important to inform other road users of your actions. However, it is the comprehensive awareness of your surroundings that should take priority to prevent accidents.
