Does this road marking allow you to go straight in this lane?

In the video you can see a lane direction arrow pointing left in your lane - marking P-8b. An arrow on the roadway is not a suggestion but an order: from the lane on which it is painted, you may go only in the direction it shows. So this lane does not allow you to go straight on.

The Regulation on road signs and signals says that lane direction arrows mean that travel from the lane in which they are placed is allowed only in the direction shown by the arrow; only combined arrows (e.g. left and straight ahead) allow both directions. It is best to check the direction of travel from a given lane early, while you are still allowed to change lanes.

Legal basis: § 87 para. 1 of the Regulation on road signs and signals
