Should you start changing lanes in this situation, if you intend to leave the highway?

In the photo, you are driving in the left lane of a motorway; on the right there is countdown marker board F-14b with the inscription "200 m", which informs you that the deceleration lane leading to the exit begins in 200 m. If you intend to leave the motorway, you should start moving into the right lane now. The answer is: yes.

The Regulation on road signs and signals states that boards F-14a, F-14b and F-14c inform you that you are approaching the beginning of the lane leading to the motorway exit, and they are placed 300, 200 and 100 m before it respectively. The Road Traffic Act requires you to change lanes with particular caution, signalling your intention in advance and giving way to vehicles travelling in the right lane. At 120 km/h, you cover 200 m in six seconds, so delaying ends with a sharp exit across two lanes or a missed exit.

Legal basis: § 74 of the Regulation on road signs and signals; Art. 22 para. 1, 4 and 5 of the Road Traffic Act (Prawo o ruchu drogowym)
