Show the correct answer
Correct answer
C. A part of the vehicle side and the space behind it corresponding to the vehicle side
Explanation
The question is about what you should see in a correctly adjusted exterior mirror of a bus. You see a part of the side of the vehicle and the area behind it on that side - answer C.
The Road Traffic Act requires a vehicle to give the driver a sufficient field of view, and the exterior mirrors are part of it. The part of the side of the bus in the mirror is a reference point: you know where your vehicle ends and how far from it a car in the next lane is. With the rest of the mirror you watch the space behind the bus and beside it. Only the area beside the vehicle (answer A) does not show what is approaching from behind, and only the area behind the vehicle (answer B) takes away your reference point. You adjust the mirrors before driving, when you are already sitting in your driving position behind the steering wheel.
