You intend to go straight ahead. Are you obliged to give way to the vehicle approaching from the right?

The recording shows an intersection with traffic lights showing a green signal for your direction. According to Art. 5 of the Road Traffic Act, light signals take precedence over general rules determining priority (including the so-called right-hand rule). Driving straight on a green light, you have the right of way over vehicles emerging from the crossroad on the right.
