In this situation, do you have priority over the vehicle driving from the left into the traffic lane?

The recording shows that you are leaving a petrol station onto a public road, which constitutes the manoeuvre of joining the traffic flow. According to Art. 17 para. 1 pt. 1 and para. 2 of the Road Traffic Act, when joining traffic, you are obliged to exercise extreme caution and yield to all vehicles already on the road. Therefore, in this situation, you do not have priority over the vehicle approaching from the left.
