What should you check before starting your vehicle?

Answer: B — Ensure mirrors are adjusted and seat is in a comfortable position

Before starting your vehicle, it is essential to ensure that the mirrors are adjusted and the seat is in a comfortable position. This step is critical for safe driving since proper adjustments help to maximize visibility and ensure the driver can reach the controls comfortably. If the mirrors are not properly positioned, the driver may have blind spots that can lead to accidents. Similarly, if the seat is not adjusted correctly, it can hinder the driver’s ability to operate the vehicle effectively and may cause fatigue during longer drives. While checking the air conditioning, radio, or fuel levels can be important for overall comfort or vehicle operation, they do not directly impact immediate driving safety or the ability to control the vehicle effectively as the correct positioning of mirrors and seat does.
