Do the visible road markings in the right lane indicate the start of an exit from the motorway?

In the photo you are driving in fog on an expressway or motorway; the right lane is separated from yours by a wide broken line, and at its end a white lane-change arrow P-9 pointing to the left is painted. These markings do not mark the start of an exit from the motorway - this is the end of an acceleration lane. The answer is: no.

The Regulation on road signs and signals states that marking P-1 of double width, in which the dashes and gaps are equal, shows that the lane is a slow-traffic lane, a lane that ends, or a lane for vehicles leaving for another road, and arrow P-9 requires you to move into the neighbouring lane. An arrow pointing to the left, towards the main roadway, tells drivers who are joining to leave the lane that is ending; at an exit the arrow would point to the right, and the exit would be announced in advance by F-14 boards and direction signs. When driving in the main lane, you watch cars joining from the right and, if possible, make room for them.

Legal basis: § 86 para. 2 point 2 and 3 and § 87 para. 3 of the Regulation on road signs and signals
