Driving on a very busy road with several lanes, you have manoeuvred yourself into the lane for taking a left turn. Now instead of turning left, you want to turn right. What should you do?

In this situation, the safest and most legally compliant option would involve a combination of actions. According to German traffic laws, once you are in a lane designated for making a left turn, it's important to follow through with that intention unless it is safe and lawful to change your plans.

If you want to turn right instead, rather than making the maneuver from the left turn lane, you should observe the traffic conditions. If it is safe to do so, you can exit the left turn lane and then proceed to make a broader turn to the right. However, reversing is not permitted unless absolutely necessary and safe, as it poses risks to other road users and could result in penalties.

Always be mindful of the signalization, other vehicles, and pedestrians around you when changing lanes or turning. Safe driving practice requires that you follow the rules to ensure your safety and the safety of others, which means fully understanding and adhering to the regulations in any given situation.
