This exam question focuses on road safety through compliance with the driver's work and rest schedule. For international bus transportation, fatigue control is critical: an overtired driver reacts worse to changes in the environment, increases the risk of traffic accidents, and violates requirements related to responsible driving. In the context of the Traffic Rules of Ukraine, this directly correlates with the prohibition against driving in a fatigued state (paragraph 2.9 "b" of the Traffic Rules).
The content of the task tests knowledge that the Traffic Rules of Ukraine set a general requirement not to drive while fatigued, but specific numerical limits for international traffic are established by special regulations, in particular the AETR. It is the AETR that defines the boundaries of the "daily driving period" and allows for an exception: the standard 9 hours may be increased to 10 hours only a limited number of times within one week. This is an important topic for the theoretical exam because it combines traffic rules with the practice of professional transportation.
The explanation of the answer options is simple: the option "once" is incorrect because the AETR explicitly allows two extensions per week; "three times" is also incorrect, as a third extension would already violate the established limit. Therefore, the correct option is two extensions, and this knowledge helps drivers plan trips without violations, avoid fines, and most importantly — maintain a safe level of attentiveness behind the wheel during international bus transportation.
Clause 2.9 (subclause "b" — prohibition of driving in a fatigued state)
The driver is prohibited from: b) operating a vehicle in a sick or fatigued state that endangers road safety.
This clause of the Traffic Rules of Ukraine is related to the need to observe the driver's work and rest schedule, but the Traffic Rules do not set specific numerical limits for the "daily driving period" for international bus transportation — such limits are determined by special international/industry regulations (in particular, AETR).
Thus, the correct answer is "Twice.", given that the Traffic Rules prohibit driving in a fatigued state, and the specific rule for international traffic (increasing the daily driving time to 10 hours) is allowed twice a week according to AETR regulations.
During international bus transportation, the driver's working hours are regulated not only by general norms but also by the requirements of the AETR. In this document, the daily driving period is defined as the time at the wheel between two rest periods: either between two daily rests or between a daily and a weekly rest.
The main rule is as follows: on a regular day, the driver must not drive more than 9 hours during this daily period. That is, the 'daily norm' for driving is set at 9 hours.
At the same time, the AETR allows a limited relaxation: within one week, this daily driving duration can be extended to 10 hours, but not without limit—only twice. This means that during the week, the driver can have a maximum of two 'extended' days of 10 hours, and on the other days of the week, the standard 9-hour limit applies.
For example, if the driver drove for 10 hours on Monday and another 10 hours on Thursday, both permitted cases of extension have already been used. Attempting to have a third 10-hour day in the same week would be a violation, as the limit for such extensions is only two times.
Therefore, the correct answer is "Twice," since within one week the AETR allows the daily driving time to be increased from 9 to 10 hours no more than in two cases.
