What should you do before changing lanes while driving?

  1. Turn on your hazard lights

  2. Check your mirrors and blind spots

  3. Signal your intent to other drivers

  4. Accelerate quickly into the new lane

The correct answer is: Check your mirrors and blind spots

Before changing lanes while driving, it is essential to check your mirrors and blind spots to ensure that the lane is clear of other vehicles and obstacles. This practice helps you maintain awareness of your surroundings, which is critical for safe driving. Mirrors provide a view of the traffic behind and beside your vehicle, but checking blind spots is equally important because some vehicles may not be visible in your mirrors. Being vigilant about these areas reduces the risk of collisions and helps you make a safer lane change. Proper checking of your surroundings promotes responsible driving behavior and enhances your ability to react to other drivers or unexpected situations.
