После того как водитель полностью проехал пешеходный переход и убедился, что на нём нет пешеходов,
обгон разрешён при соблюдении всех общих условий безопасности.
ПДД КР не ограничивают количество одновременно обгоняемых транспортных средств,
если выполняются требования пунктов 11.1 и 11.5 и видимость дороги позволяет безопасно завершить манёвр.
Следовательно, можно обогнать все три транспортных средства сразу после проезда перехода,
если обгон не создаст опасности и не нарушит другие пункты Правил.
Ответ — Все три
ПДД КР пункты 11.1 и 11.5
Before starting to pass, the driver must make sure that:
The lane they want to enter is clear for a safe passing distance. The driver must not block oncoming vehicles or vehicles already in that lane;
The vehicle behind them in the same lane has not started to pass. The vehicle ahead has not signaled to pass, turn left, or change lanes to the left;
After passing, they can return to their previous lane without blocking the passed vehicle;
Outside residential areas, the driver may honk the horn to warn other drivers that they plan to pass.
Passing is banned:
At controlled intersections when entering the oncoming lane. At uncontrolled intersections when driving on a road that is not a priority road. (Exceptions: passing at traffic circles, passing two-wheeled vehicles without a sidecar, and allowed passing on the right);
At crosswalks;
At railroad crossings and closer than 100 meters before them;
When the vehicle ahead is passing or going around an obstacle;
At the end of an uphill or on other road sections with poor visibility when entering the oncoming lane;
When passing a group of vehicles escorted by a vehicle with a flashing light (except orange and yellow lights);
On bridges, overpasses, under them, and in tunnels.
