Is it forbidden to perform a reverse manoeuvre on an express road?

In the photo, you are driving in fog on a multi-lane road, with signs D-3 "one-way road" and D-7 "expressway" on the right. Reversing a vehicle on an expressway is prohibited. The answer is: yes.

The Road Traffic Act explicitly lists the places where you must not reverse: a tunnel, a bridge, a flyover, a motorway and an expressway. The Regulation on road signs and signals states that sign D-7 marks the beginning or continuation of an expressway. The ban is absolute - there are no exceptions for a short distance, for hazard warning lights switched on or for light traffic, because at high speeds even a moment of reversing in a lane can end in a rear-end collision. If you have missed your exit, you continue driving to the nearest interchange.

Legal basis: Art. 23 para. 2 of the Road Traffic Act (Prawo o ruchu drogowym); § 48 para. 1 of the Regulation on road signs and signals
