Under what conditions is it obligatory to operate a “speed retarder” while driving downhill?

• When the vehicle is equipped with a speed retarder and a sign warning about a dangerous descent is placed on the road.
• When the slope rate of the decent exceeds 6% and the length of the decent is more than one kilometer.
• When a “warning sliding” sign is placed on the road.
• If a vehicle is equipped with a speed retarder, it should always be operated, also while driving on plane surfaces.
