Show the correct answer
Correct answer
B. a part of the vehicle side and the area behind the vehicle corresponding to the vehicle side.
Explanation
This question is about what a correctly adjusted external mirror of an agricultural tractor shows. It shows a part of the side of the vehicle and the area behind the vehicle on the corresponding side - answer B.
A narrow strip of the side of the tractor or trailer at the inner edge of the mirror is a reference point: thanks to it, you can judge how far from your vehicle a car visible in the mirror is and whether it will fit next to you. The rest of the mirror shows the road behind the vehicle on the given side - in the left mirror, the next lane and overtaking vehicles; in the right mirror, the right edge, cyclists and pedestrians. The area beside the vehicle alone (answer A) will not let you see vehicles approaching from behind, and the area behind the vehicle alone (answer C), without a reference point, makes it difficult to judge distances. The rules require the mirrors of a tractor to provide an adequate field of view of the road to the rear. You adjust them before driving, sitting in your normal position.
