While driving an agricultural tractor with one-axle trailer through a curve, you should take into account that:
Show the correct answer
Correct answer
A. the trailer is moving on a smaller radius than the tractor.
Explanation
This question is about driving round a bend with an agricultural tractor and a single-axle trailer. The trailer follows a smaller radius than the tractor - answer A.
A single-axle trailer is pulled by the hitch at the rear of the tractor, and its wheels follow this point, "cutting" the corner - they move closer to the inside of the bend than the wheels of the tractor. The longer the trailer with its drawbar and the sharper the bend, the bigger this difference. That is why answers B and C are wrong. In practice, when turning right, the trailer may run over a kerb, a post, a sign or a pedestrian standing at the edge, even though the tractor passed them without any problem. So you turn in a wider arc, watching the path of the trailer in the right mirror, and when the dimensions of the combination do not allow a normal turn, you may start the right turn further from the right edge of the roadway.
