Stop - Greek road sign R-2 according to road traffic codex 2009 (KOK 2009).  1) This sign, when it's placed before a junction, means the mandatory stopping of the vehicle before entering the junction and the prioritization of the vehicles moving on the road to which it is approaching. (2) When placed to points other than a junction, means a mandatory stopping of the vehicle in the position of the sign and not start until the driver is sure that they can do so without risk.
