While driving a truck, what should you see in properly-adjusted external mirrors ("rear-view mirrors")?

Explanation
Correct answer: The area behind the truck and the sides of the truck.
Properly adjusted side mirrors must provide the driver with a view of the area to the side and rear of the vehicle. Showing a portion of the vehicle's own side in the mirror is crucial, as it serves as a reference point that allows for the correct assessment of the distance and speed of other road users, which is essential for performing manoeuvres safely.
