What must you do to ensure a safe lane change?

Answer: C — Check mirrors, use turn signals, and check blind spots

To ensure a safe lane change, it’s essential to check mirrors, use turn signals, and check blind spots. This comprehensive approach allows a driver to be fully aware of their surroundings. Checking mirrors gives you a view of vehicles behind and beside you, providing an idea of the traffic situation. Using turn signals is critical as it communicates your intention to other drivers, allowing them to anticipate your movement. Finally, checking blind spots is vital since mirrors don’t cover all angles; vehicles or cyclists could be present without being visible in the mirrors. By incorporating all these steps, you significantly reduce the risk of accidents during lane changes, contributing to safer driving practices.
