What should you do before changing lanes in a vehicle?

Answer: A — Check your mirrors and blind spots

Before changing lanes in a vehicle, it is crucial to check your mirrors and blind spots. This practice ensures that you are aware of your surroundings, particularly other vehicles that may be in adjacent lanes that might not be visible in the mirrors. Checking mirrors allows you to see the traffic behind and beside you, while monitoring blind spots—areas that cannot be viewed in your mirrors—protects you from potential collisions. This comprehensive checking makes it possible to safely maneuver into the new lane without causing accidents. Utilizing a turn signal is also a vital step leading up to the lane change, indicating your intentions to other drivers. This enhances road safety by alerting those around you to expect your movement. By adhering to these steps, you contribute to a safer driving environment for yourself and others on the road.
