You have taken the right lane by mistake although you want to turn left. How are you allowed to proceed?

You answered correctly! In this situation, if you have accidentally taken the right lane but want to turn left, you are only allowed to proceed straight ahead or turn right, according to the lane markings and arrows on the road. Turning left from the right lane is not permitted, even if the traffic lights are green. This rule ensures safe and predictable traffic flow, preventing dangerous lane changes or conflicts with other vehicles. In future situations, always follow the direction indicated for your lane and only change lanes when it is safely possible and allowed.
