Are you allowed to turn left from the lane you are occupying?

A yellow directional arrow (temporary marking) is visible in your lane, indicating only the right-turn direction. According to § 87 para. 1 pt. 2 of the Regulation, this sign permits movement only in the direction indicated by the arrow. Furthermore, under § 85 para. 3, yellow road markings take precedence over white ones, so performing a left turn from this lane is prohibited.
