Clause 2.3 (Section 2 "Duties and Rights of Drivers", driver’s duties regarding safety and technical condition of the vehicle)

To ensure road safety, the driver is obliged to: a) before departure, check and ensure the technical serviceability and completeness of the vehicle, the correct placement and securing of cargo; b) be attentive, monitor the traffic situation, respond appropriately to its changes, monitor the technical condition of the vehicle, and not be distracted from driving it.

Application to the question: "ensure technical serviceability" in the context of traffic safety includes ensuring proper visibility (cleaning windows/mirrors from snow and ice) and the vehicle’s visibility for other road users (cleaning lighting devices so they perform their function).

Clause 31.4.7 (Section 31 "Technical condition of vehicles and their equipment", prohibition of operation — visibility restrictions)

Operation of vehicles is prohibited under the law if additional objects are installed or coatings are applied to the glass that provides visibility from the driver’s seat, which restrict visibility from the driver’s seat and reduce its transparency (except in cases provided by these Rules).

Application to the question: snow and ice on the windshield (as well as other windows) are in fact a "coating" that reduces transparency and visibility. Therefore, cleaning only part of the windshield does not fulfill the requirements for visibility before starting to drive.

Thus, the correct answer is "No.", given that according to the definition of the Traffic Rules, the driver before starting to drive is obliged to ensure a safe technical condition and proper visibility, and a coating (snow/ice) on the glass and other elements affecting visibility/recognizability contradicts this.

Before starting to drive, the driver is required to ensure safe control, which according to the Traffic Rules is directly related to sufficient visibility and the proper functioning/visibility of external lighting devices. In winter, these conditions are most often violated due to snow and ice on the vehicle, so simply cleaning the windshield is not enough.

If you clean only the windshield but leave snow or ice on the side windows and mirrors, the driver will not have full visibility when changing lanes, turning, or reversing. This contradicts the very requirement of the Traffic Rules to drive the vehicle in such a way as to constantly monitor the traffic situation, since "blind spots" and fogged/snow-covered glass prevent you from noticing a pedestrian, cyclist, or another car in time.

A separate danger in winter arises when snow remains on the roof or hood. As the car warms up, it melts, and when braking, it can suddenly slide onto the windshield and block the view at the very moment the driver needs to see the road. In such a situation, the wipers may not cope with the heavy mass of snow, and the vehicle is essentially moving without visibility, which creates a real risk of an accident.

It is equally important to clean the headlights, side lights, turn indicators, and brake lights. In winter, they quickly get dirty, and if you leave them under a layer of snow or dirt, other road users will see your car later or may not understand your intentions. This already violates the principle of safe interaction on the road: you must be clearly seen and your signals correctly understood.

Therefore, the correct answer is "No," because in winter, to safely start driving, you need to clean not only the windshield but also other elements that ensure the vehicle's visibility (all windows, mirrors, roof/hood from snow, and external lighting devices).
