Show the correct answer
Correct answer
A. Looking through the rear windshield and in the external mirrors.
Explanation
This question is about controlling your path when reversing an agricultural tractor with a trailer. The driver looks through the rear window and in the external mirrors - answer A.
Each of these sources shows something different. Through the rear window you see the trailer, its drawbar and the space directly behind the tractor, and in the external mirrors - the sides of the trailer, its rear corners, and whether you are getting close to a ditch, a fence or another vehicle. If you look only through the rear window (answer B), you will not see what is happening along the sides, and the trailer often blocks the view behind it. The mirrors alone (answer C) will not show the drawbar or the space just behind the tractor, and through the rear window it is easier to notice the moment when the trailer starts to jackknife. The Road Traffic Act requires you to exercise particular caution when reversing and to make sure that there is no obstacle behind the vehicle, and if it is difficult, to use the help of another person.
