You now want to turn right at these traffic lights with a green arrow sign. What is the right course of action?

In the scenario shown, if you want to turn right at traffic lights with a green arrow sign, it's important to follow proper procedures.

When approaching an intersection with a traffic light, you should first halt at the stop line. This ensures that you have the opportunity to check for any pedestrians or other road users who may be crossing or who have the right of way.

Next, you need to ensure that no other road users are impeded. This includes checking for cyclists, pedestrians, or vehicles that may be in your path before making the turn.

The third option of turning without stopping at walking speed is incorrect in this context because you still have the responsibility to check for other road users and ensure their safety. Making a turn without stopping may lead to accidents if you do not properly observe the intersection.

Thus, both halting at the stop line and ensuring that other road users are not impeded are critical steps according to German traffic laws to maintain safety and compliance.
