33.4.32. The depicted road sign informs about a road:
UAЗображений дорожній знак інформує про дорогу:
This is an exam question from the Traffic Rules of Ukraine concerning the recognition of road signs and directly affecting the safety of interaction among different road users. In driving practice, it is important to timely understand where the traffic regime changes and which vehicles are allowed to travel on a particular section, as a mistake can lead to dangerous situations or violations of traffic rules.
Section 33 "Road Signs" is being tested, group 4 "Mandatory Signs", specifically sign 4.23, which indicates the beginning of a local road intended for shared (combined) use by cyclists and passenger cars. An important detail for the theoretical exam: only passenger cars and bicycles are allowed on this section, so the sign does not simply "warn about bicycles," but establishes a special mode of road use.
Analyzing the answer options in such tasks helps to avoid confusing similar situations. The statement about a contraflow bicycle lane refers to the organization of lanes and their directions, but sign 4.23 does not mean the presence of a separate "contraflow" bike lane. The option about crossing a bicycle path with the roadway describes a different type of information (about a crossing point), whereas here it is about the start of a special road with shared movement. Thus, the correct interpretation is that this is a road where only passenger cars and cyclists move together, and the driver must be prepared for the constant presence of bicycles in the flow and choose speed and distance considering this regime.
Clause 33.4 — 33 "Road Signs", 4 "Mandatory Signs", sign 4.23 "Road for combined movement of passenger cars and cyclists"
"Indicates the beginning of streets and roads of local importance (except pedestrian streets), intended for the combined movement of cyclists and passenger cars. All other road users are prohibited from traveling on this section of the road." (The essence of this sign is what is being checked in the question: which road does it indicate.)
Clause 1.10 (term "Bicycle")
"Bicycle — a vehicle, except for wheelchairs, driven by the muscular power of the person operating it."
Clause 1.10 (term "Cyclist")
"Cyclist — a person who operates a bicycle."
Clause 1.10 (term "Passenger car")
"Passenger car — a car that by its design and equipment is intended for transporting passengers with no more than nine seats including the driver's seat."
That is, the correct answer is "For combined movement of passenger cars and cyclists," given that according to the definition in the Traffic Rules, sign 4.23 directly indicates the beginning of a road/street intended specifically for the combined movement of cyclists and passenger cars, and other road users are prohibited from using it.
Road sign 4.23 informs the driver that ahead begins a section of a local road where combined movement of two categories of road users is organized: passenger cars and cyclists. That is, this is not a separate bicycle path and not an ordinary road for any type of vehicle, but a specially designated section for the joint use of the carriageway specifically by these participants.
In practice, this means that on such a road, you, as the driver of a passenger car, must be prepared for the constant presence of cyclists in the traffic flow. For example, a cyclist may move ahead within the lane, perform maneuvers according to the Rules, and the driver of the car must choose a safe speed and distance taking into account this shared movement.
At the same time, sign 4.23 sets restrictions for other road users: if you are driving something other than a passenger car (for example, a truck or a bus) or are operating another type of vehicle, entry to this section is prohibited. In this way, the specific regime indicated by the sign is ensured: shared movement only for passenger cars and bicycles.
Therefore, the correct answer is "For combined movement of passenger cars and cyclists," since sign 4.23 marks the beginning of a road intended for the joint movement of only passenger cars and cyclists, and movement by other road users is prohibited.
