What should you do before changing lanes?

Answer: A — Check your mirrors and blind spots

Before changing lanes, it is essential to check your mirrors and blind spots. This practice ensures that you have a clear understanding of the surrounding traffic conditions. By checking mirrors, you can see vehicles in adjacent lanes, while looking into blind spots allows you to identify any vehicles that may not be visible in your mirrors. This step is crucial for safety, as it helps prevent collisions with other road users who might be in your path when you attempt to change lanes. Engaging in this precautionary measure contributes to safer driving and enhances your ability to make informed decisions while on the road. Proper signaling and awareness of the traffic around you are key components of lane changing that can significantly reduce the risk of accidents.
