If a policeman raises his arm or forearm of his right hand with an indicator sign, this instructions means
a) „Stop!“ for the direction that he faces or has behind his back,
b) „Go for the direction, to which he stands with his side,
c) “Caution!”; a driver of a vehicle driving from the direction, where traffic was stopped before, is obliged to be prepared for driving; a driver of a vehicle driving in the direction that was free before, is obliged to stop the vehicle in front of line of the intersection; if he is so close that he would not be able to stop the vehicle safely, he can continue in driving.
