Priority, Intersections and Overtaking
Priority questions are the most heavily tested in Armenia, and most errors come from forgetting the hierarchy. The order is: traffic controller, then traffic lights, then signs, then the general "priority to the right" rule. If a junction has no signs and no lights, you give way to traffic approaching from your right. If a priority-road sign is present, traffic on the priority road goes first. A give-way sign means yield; a stop sign means stop completely at the line, then yield.
At roundabouts, traffic already on the roundabout has priority unless signs say otherwise. When turning left, you yield to oncoming traffic going straight or turning right. When turning right, you yield to pedestrians and cyclists crossing the road you are entering. Unmarked junctions in residential areas still follow priority to the right.
Overtaking is permitted only when visibility and markings allow, and never at pedestrian crossings, on bridges, at level crossings, or where a solid line separates you from the lane you want. Overtake on the left; overtaking on the right is allowed only when the vehicle ahead is signalling a left turn and there is room.
Worked example: two cars arrive at an unmarked crossroads at the same moment, one from your right. You yield, even if you arrived first. If a priority-road sign faces you, you go first and the car on your right yields.
Rule of thumb: when in doubt at an unsigned junction, look right and yield.
