What should you do before changing lanes?

  1. Check your GPS for the best route

  2. Signal your intention and check visual mirrors

  3. Turn on your hazard lights

  4. Speed up to merge effectively

The correct answer is: Signal your intention and check visual mirrors

Before changing lanes, it is essential to signal your intention and check visual mirrors. Signaling alerts other drivers of your plans, which is crucial for maintaining safety on the road and ensuring that other vehicles are aware of your movement. This helps to prevent misunderstandings and potential collisions. Checking your mirrors allows you to assess the traffic around you, ensuring that the lane you want to move into is clear of vehicles and that there is enough space for a safe lane change. This two-step process—signaling and checking mirrors—plays a vital role in defensive driving, promoting awareness and safety by keeping both the driver and other road users informed.
