Clause 1.10 (term “Route vehicles”)

Route vehicles — buses, minibuses, trolleybuses, and trams that operate on established routes and have designated stops (for boarding/alighting passengers).

Clause 33.3 — 33 “Road signs”, 3 “Prohibitory signs”, sign 3.1 “No entry for all vehicles”

“No entry for all vehicles” — prohibits the movement of all vehicles.

The sign does not apply to vehicles operating on established routes; (as well as to other vehicles in cases directly provided for by the Traffic Rules for this sign).

Clause 33.3 — 33 “Road signs”, 3 “Prohibitory signs”, sign 3.21 “No entry”

“No entry” — prohibits entry for all vehicles.

The sign does not apply to vehicles operating on established routes.

That is, the correct answer is “Allow the movement of route vehicles,” given that according to the Traffic Rules, the effect of signs 3.1 and 3.21 does not apply to vehicles operating on established routes (route vehicles).

Both signs belong to the prohibitory category and at first glance are perceived as a complete ban on movement: sign 3.1 "No entry" generally prohibits the movement of vehicles in the specified direction, while sign 3.21 "Entry prohibited" specifically prohibits entry to a certain section (for example, to prevent oncoming traffic or entry onto a separate lane).

The common feature between them is that the description of each of these signs in the Traffic Rules explicitly provides an exception: their effect does not apply to vehicles operating on established routes. That is, a route bus, trolleybus, or other route transport performing transportation on an approved route has the right to pass where the prohibition applies to most drivers.

For example, if sign 3.1 is installed at the entrance to a short section of road, an ordinary passenger car cannot enter, but a route bus that passes through this section according to its route has the right to continue moving. The same applies to sign 3.21: it prohibits entry to all vehicles, but route transport operating on an established route is not subject to this prohibition and may enter to carry out its service.

Therefore, the correct answer is "Allow the movement of route vehicles," since both signs are prohibitory, but according to the Traffic Rules, their effect does not apply to vehicles operating on established routes.
