On your 10 m-long vehicle, the load is projecting 60 cm over the vehicle’s rear edge. What applies to you when this traffic sign is displayed?

This traffic sign indicates a length restriction: vehicles longer than 10 meters (including load) are not allowed to enter. For driving safety and to avoid trouble on narrow streets or tight curves, your vehicle’s total length is what matters—not just the official vehicle length, but also any load projecting beyond the rear edge.

In your situation, your vehicle is 10 meters long, and the load extends another 60 centimeters at the back, making the total length 10.6 meters. Since this exceeds the 10-meter limit set by the sign, you are not allowed to enter, and it does not matter if the load is specially marked. Always calculate total length with the load included to comply with such restrictions.
