Municipalities designate a certain number of parking spaces, particularly in city centers, for use by severely disabled persons with exceptional walking disabilities and blind persons. This is done with the blue P sign and an additional sign with the wheelchair user symbol or an additional sign expressly requesting the display of a parking permit.

The authorization to use these specially marked parking spaces is evidenced by a special parking permit in light blue or blue. The permit must be clearly legible on the outside of the vehicle (e.g. on the dashboard).

The required exemption permit and the parking permit can be applied for at the municipality of residence. The display of the disabled person's ID card or other ID cards (e.g. orange parking permit) alone is not sufficient to prove authorization to use the specially marked disabled parking spaces. Only the light blue (European) or dark blue (marked "BY only") parking permit is valid here. Parking permits "BY only" are no longer issued, but remain valid until the expiration date indicated on them.

For this group of people, the opportunity to use appropriately signposted parking spaces in central locations is not a privilege, but merely compensation for a very difficult life situation. For many of these severely disabled people, an occupied disabled parking space means that they may have to return home without having achieved anything. Due to their severe disability, for example, they cannot simply get out of the car to see if someone could drive away an (illegally) parked vehicle at short notice.

For this reason, the police pay particular attention to these parking spaces and have unauthorized vehicles parked there towed away.

If an applicant does not meet the requirements for the issue of a blue parking permit for severely disabled persons, parking concessions may be granted in the case of certain illnesses by issuing an exemption permit in accordance with § 46 Para. 1 No. 11 StVO with the issue of an orange parking permit. This special permit can also be used to grant parking concessions (e.g. free parking at a parking meter), but does not entitle the holder to use the specially marked disabled parking spaces ("wheelchair symbol").
