The sign in the question prohibits all vehicles from overtaking motor vehicles travelling on the carriageway when such a manoeuvre involves crossing into the lane reserved for oncoming traffic. The prohibition applies from the point where the sign is located until the next 'End of no overtaking' or 'End of prohibitions' sign.
Placed in locations where overtaking is prohibited by regulation, it serves as a general reminder of the prohibition to carry out this manoeuvre.
