Answer :
"Do not overtake turning vehicle" sign on your vehicle means that when turning left you may move out of the left lane B. 100 metres from the corner.
50 metres from the corner: This distance may not be sufficient, as drivers often need more space to ensure that it is safe to overtake without obstructing the turning vehicle.
100 metres from the corner: This distance allows some room for cautious assessment of the surroundings while preventing potential conflicts with vehicles that are preparing to or are already turning. It gives drivers the necessary time and space to react.
200 metres from the corner: While this is a larger distance that may seem safer, it may not always be practical in urban settings where roads can be congested and spaces are limited.
