When driving on a dual carriageway in very unfavorable weather and environmental conditions, how must you act if you see a recommended speed range sign (S-9)?

Question

DentroTest · Accepted Answer

Vertical sign S-9 (recommended speed range) belongs to the group of information signs. It recommends keeping speed within the values it shows, provided that the weather and environmental conditions of the road and traffic are favorable. Therefore, if there are very adverse weather conditions (heavy rain, snow, ice or dense fog), speed must be adapted to the real circumstances in order to maintain control and safety distance, even if that means driving clearly below the figures suggested on the sign. It is not true that it requires keeping a speed within the range: this sign imposes no obligation (mandatory signs are circular with a blue background, like R-411, minimum speed), and neither does it set different criteria according to the vehicle's maximum authorized mass (MAM).
