You have manoeuvred into the left lane by mistake, but would like to take a right turn. What is the right course of action?

In this situation, you are in the left lane, and the lane markings show that it is only allowed to go straight ahead or turn left from here. If you want to make a right turn but are already in the left lane, you must not change lanes or make the turn from your current position, as this would be unsafe and against traffic rules. Instead, you should either continue straight ahead or turn left, following the permitted directions for your lane. Changing lanes at the last moment or turning from the wrong lane can endanger yourself and other traffic participants. In the future, always plan your lane position early to match your intended direction.
