Which is NOT a responsibility of drivers before moving their car?

Adjusting mirrors is indeed an important aspect of preparing to drive, but it is not a complete representation of the broader responsibilities drivers have before moving their car. It is crucial for drivers to ensure that their mirrors are adjusted correctly for optimal visibility; however, this should not be the only consideration when preparing to drive.

Drivers need to check their seatbelt for safety, confirm their understanding of the vehicle's controls and gadgets, and ensure that everything inside the car is properly secured to prevent distractions or hazards. Each of these responsibilities contributes to safe driving practices, while simply adjusting the mirrors does not encompass the full scope of what is required before commencing a drive. Thus, while adjusting mirrors is one responsibility, it does not stand alone as the only preparation necessary for a safe driving experience.
