Do you live in Lower Saxony and need a parking permit for the severely disabled?

Severely disabled persons with an exceptional walking disability (mark "aG") or blind persons (mark "Bl") can apply for a parking permit. The Lower Saxony State Office for Social Affairs, Youth and Family or its branch offices determine the requirements for the award of the "aG" sign.

The parking permit for severely disabled persons must be applied for at the responsible office.
