Clause 9.8 (subclause "g")

When driving motor vehicles during daylight hours, in order to indicate a moving vehicle, the low beam headlights must be turned on: … g) on heavy and oversized vehicles, agricultural machinery with a width exceeding 2.6 m, and vehicles transporting dangerous goods; … From October 1 to May 1, all motor vehicles outside populated areas must have daytime running lights on, and if the vehicle's design does not provide for them, the low beam headlights must be turned on.

This clause directly establishes the obligation to turn on the low beam headlights (as a warning/identification signal) when driving heavy and oversized vehicles during daylight hours.

Clause 22.6

Vehicles transporting dangerous goods by road must move with the low beam headlights on, rear position lights on, and with identification signs as provided in clause 30.3 of these Rules, and heavy and oversized vehicles, as well as agricultural machinery with a width exceeding 2.6 m, must also have an orange flashing beacon (beacons) turned on.

This clause directly indicates that for heavy/oversized vehicles, an additional orange flashing beacon must be turned on.

Clause 3.6

Turning on the orange flashing beacon on vehicles with the identification sign "Children", on road maintenance service vehicles while working on the road, on oversized and heavy vehicles, on agricultural machinery with a width exceeding 2.6 m, does not grant them priority in traffic, but serves to attract attention and warn of danger. At the same time, drivers of road maintenance service vehicles while working on the road are allowed to disregard the requirements of road signs (except for priority signs and signs 3.21, 3.22, 3.23), road markings, as well as clauses 11.2, 11.5, 11.6, 11.7, 11.8, 11.9, 11.10, 11.12, 11.13, subclauses "b", "v", "g'" of clause 26.2 of these Rules provided that road safety is ensured. Drivers of other vehicles must not interfere with their work.

This clause explains the purpose of the "warning signal" in the form of an orange flashing beacon specifically for oversized and heavy vehicles (to attract attention and warn of danger).

Thus, the correct answer is "Answers 1 and 2.", considering that according to the Traffic Rules, for heavy/oversized vehicles during movement, the use of low beam headlights (clause 9.8 "g") and an orange flashing beacon (clause 22.6, with its warning purpose clarified in clause 3.6) is mandatory.

When a heavy or oversized vehicle is moving on the road, it must be clearly marked for other road users. This is done with warning signals so that drivers can understand in advance: there is a vehicle nearby with non-standard dimensions or weight, which may move more slowly, occupy more of the lane, or require a greater distance for maneuvering.

According to clause 9.8 (d) of the Traffic Rules, during daylight hours such vehicles must drive with their low beam headlights on (or daytime running lights, if they are part of the vehicle's design). That is, the low beam is turned on specifically as a means of marking the vehicle in the traffic flow.

In addition, clause 22.6 of the Traffic Rules directly states that heavy and oversized vehicles must also have an orange flashing beacon turned on while driving. Clause 3.6 clarifies the purpose of such a beacon: it does not grant priority in traffic, but only attracts attention and warns of potential danger, that is, it is specifically a warning signal.

Imagine a wide platform with cargo driving ahead: the low beam headlights help to notice it as a vehicle, and the orange flashing beacon further emphasizes that this is not a regular car and should be treated with extra caution (increase distance, overtake more carefully, etc.).

Therefore, the correct answer is "Answers 1 and 2," since for heavy and oversized vehicles, the Traffic Rules require that both the low beam headlights (clause 9.8 (d)) and the orange flashing beacon (clause 22.6, with the explanation of its purpose in clause 3.6) be turned on simultaneously while driving.
