Do the visible horizontal signs in the form of arrows on the roadway, impose driving solely in the indicated direction from the traffic lanes on which they are currently driving?

In the video you are approaching a junction with traffic lights on a wide street; the traffic lights show green, and white lane direction arrows are painted in the lanes - in your lane a combined straight-on and right arrow, in the neighbouring lanes straight-on arrows, and in the far left lane a left arrow, just as on sign F-10 before the junction. Such arrows require you to drive only in the direction shown from the lane in which they are placed. The answer is: yes.

The Regulation on road signs and signals states that markings P-8a "straight-on lane direction arrow", P-8b "lane direction arrow for turning" and P-8c "lane direction arrow for a U-turn" mean that driving from the lane in which they are placed is allowed only in the direction shown by the arrow, and combined symbols of these arrows mean permission to travel in the directions shown. The arrows on the roadway work like sign F-10 by the road and apply whatever the colour of the light - green allows you to move off, but only where the arrow points. You choose your lane in advance, reading the arrows several dozen metres before the junction, because just before it the lines between lanes usually become solid, and changing lanes is then prohibited.
