How to call the notice that it is forbidden to pile up electric cars in the corridor?

Dear owners, the corridor is a public area, which belongs to all owners and any individual.

There is no unauthorized occupation.

Article 28 of the Fire Protection Law stipulates: "No unit or individual may occupy, block or close evacuation passages, fire passages and fire truck passages." As an important fire escape exit, the corridor must be kept safe and smooth at all times.
