You intend to turn left and the driver of the oncoming vehicle intends to go straight ahead. Have you got priority before him?

In the video, you are driving a lorry on a priority road marked with sign D-1 with plate T-6a, which shows that the priority road turns left at the junction; you position yourself in the left lane (for turning left and going straight on), and an oncoming lorry is going straight on. You have right of way over it. The answer is: yes.

The Regulation on road signs and signals states that plate T-6a placed under sign D-1 shows the actual course of the priority road through the junction, and the Road Traffic Act gives signs precedence over the general rules. Normally a driver turning left gives way to an oncoming vehicle going straight on, but here the priority road bends to the left together with you: when you turn, you stay on the priority road, and the vehicle going straight on leaves it and enters a minor road - in practice it is coming from a road with sign A-7 and plate T-6c. It is that vehicle that must give way to you. Collisions often happen at such junctions, because drivers going "straight" instinctively feel that they have priority. That is why you turn with particular caution, watching whether the driver of the oncoming lorry is really braking, and remembering the pedestrians on the crossing after the junction.

Legal basis: § 43 para. 1 and 2 and § 5 para. 5 and 7 of the Regulation on road signs and signals; Art. 5 para. 1 and Art. 25 para. 1 of the Road Traffic Act (Prawo o ruchu drogowym)
