In what circumstances should a cargo protruding from the back of a trailer pulled by an agricultural tractor be marked?

Explanation
Correct answer: If it protrudes over 0.5 meter behind the rear surface contour of the vehicle.
According to road traffic regulations, a load protruding from the rear of a vehicle (other than a passenger car) must be marked if it protrudes by more than 0.5 m from the rear plane of the vehicle's contour. In the case of the agricultural tractor trailer shown in the photo, a load protruding up to 0.5 m does not require marking. Such marking consists of white and red stripes.
