When should you check your mirrors while driving a commercial vehicle?

Answer: B — Regularly and before any maneuvers

Checking your mirrors regularly and before any maneuvers is essential for safe driving in a commercial vehicle. This practice allows drivers to maintain awareness of their surroundings, including the positions of vehicles, pedestrians, and other potential hazards. Regular mirror checks help in monitoring blind spots and ensuring that the driver can make informed decisions while on the road. When preparing to change lanes, make turns, or merge, the driver must confirm that the conditions are safe. Relying solely on checks during specific situations, such as only during lane changes or only before making turns, can lead to dangerous oversights, as the driving environment can change rapidly. Hence, a proactive approach to mirror checks enhances overall safety and minimizes the risk of accidents.
