A parking lot barrier is necessary if the loading and unloading of a removal transport cannot be carried out without disrupting road traffic. This is the case if the removal transport will take place in an area where

• a stopping or parking ban applies,
• parking is permitted (e.g. in parking spaces - including hard shoulders, on residents' parking spaces, in a short-term parking zone)
• there is a pedestrian zone
• the sidewalk is fully or partially obstructed or blocked, e.g. by a furniture lift.

The competent authority issues an order after the application has been submitted. This contains information on how the area in question is to be marked. The relevant traffic signs (no stopping signs) may only be erected once the order has been received. The no stopping signs can be borrowed from the responsible authority or from specialist companies (traffic engineering), forwarding agents and, if necessary, from the depot.

No unauthorized parking spaces may be reserved on public roads without prior permission (e.g. by placing garbage cans).
Other road users do not have to respect unauthorized reservations.
