What should you do before changing lanes?

Before changing lanes, it is crucial to ensure safety by looking in your mirrors and checking your blind spot. This practice helps you be aware of your surroundings and allows you to detect any vehicles or obstacles that may not be visible in your mirrors alone. Properly checking your blind spot is essential because it ensures that you do not collide with another vehicle that might be in the lane you intend to enter. This step is a fundamental part of safe driving and is aligned with safe driving regulations and best practices.

Turning on your radio does not contribute to lane change safety, and signaling only when there are cars around fails to acknowledge that you should always communicate your intentions to all road users. Simply changing lanes without checking is unsafe, as it increases the risk of accidents, which is why thorough observations are vital before making any lane changes.
