Traffic Signals and Right-of-Way
Signal types and their meaning
Bulgarian signals include the standard three-lamp vehicle light, pedestrian lights, and special lights such as flashing amber (proceed with caution, give way as at a give-way), and lane-control signals. A green light means you may proceed if the exit is clear; you must not enter a junction you cannot clear. A flashing green, where used, warns that the phase is ending. A red plus amber combination means prepare to go but do not move until green.
Priority at junctions
The general right-of-way rule is 'give way to traffic approaching from the right' at unsigned junctions. This is displaced by signs, signals, or a priority road. When turning left across oncoming traffic, you must give way to oncoming vehicles going straight or turning right. When entering a roundabout, give way to traffic already circulating unless signs say otherwise. Tram priority is strong: give way to trams on their tracks.
Traps in right-of-way questions
Questions often place a motorcycle at a junction with a vehicle from the right and a priority sign on the motorcycle's road. The sign wins over the 'right-hand rule'. Another trap is the flashing amber: candidates treat it as green and fail to give way. A third is the left-turn scenario where a motorcycle must yield to an oncoming car even if the motorcycle arrived first.
Worked example
You are on a priority road, a car approaches from a side road on your right. Because your road is the priority road, the car must give way; the right-hand rule does not apply. But if you are turning left across an oncoming car, you must still yield to that car.
Rule of thumb
Ask in order: any officer? any signal? any sign? If none, apply the right-hand rule and tram priority.
