What is allowed at this traffic sign?

This traffic sign indicates a no stopping zone ("No stopping" sign). According to German traffic rules:

- You are allowed to wait for a short time, up to 3 minutes, without leaving the vehicle. This is called "waiting" and is permitted to avoid unnecessary traffic obstruction.
- You can also stop briefly for loading or unloading goods, or for passengers to board or alight. This is considered a "stop," not parking, and is allowed momentarily.
- However, parking is strictly prohibited here, even with a parking disc. Parking means leaving the vehicle unattended for a longer time, which would block traffic in this zone.

Understanding the difference between waiting, stopping, and parking is key. This sign forbids parking, but allows short stops as described for practical reasons without disturbing traffic.
