What specifically does the P-31 warning sign showing the silhouette of three aligned cars indicate?

Question

DentroTest · Accepted Answer

The correct answer is that it warns of potential traffic congestion ahead. This is the P-31 sign ('Congestion'), which indicates danger due to the proximity of a section where traffic flow is stopped or hindered by a build-up of vehicles. Upon seeing it, the driver must moderate speed and increase safety distance to avoid rear-end collisions. The other options are incorrect because this is not a prohibition sign (it does not explicitly forbid overtaking, although the situation makes it inadvisable) nor does it indicate a narrowing of the road (which is the function of sign P-17).
