1. Traffic on this section of the road is allowed at a speed of no more than 50 km/h.
It is recommended to drive on this road section at a speed of 50 km/h.✓Правильный ответ
The traffic is only allowed at the speed indicated on the sign or more.
Объяснение
A white speed value on a blue square recommends 50 km/h for the section. It is neither a red-bordered maximum limit nor a blue circular minimum-speed command, so the other readings assign regulatory force that the sign does not have.
