How many mirrors should a tractor be equipped with?
Show the correct answer
Correct answer
B. At least two external mirrors, one on the left, and one on the right.
Explanation
In the photo, a large rectangular external mirror on an arm is seen from the tractor cab. An agricultural tractor should have at least two external mirrors, one on the left and the other on the right side - answer B.
The rules on the technical conditions of vehicles require an agricultural tractor to have at least two external mirrors, on the left and on the right side, giving a proper field of view of the road behind on both sides of the trailer being pulled. One left mirror (answer A) is not enough - a tractor usually pulls a wide trailer or machine that blocks the view, so you must see the road behind it on both sides. An interior mirror (answer C) is not required in a tractor, because through the rear window you mainly see the trailer. The exception concerns tractors registered before 1994 that have no cab or protective frame - these may be driven without external mirrors. Before driving with a wider trailer, adjust the mirrors so that you can see the road along its sides.
