It is imperative that fire lanes be kept clear of vehicles at all times. Esign's Fire Lane signs are perfect for marking those areas as no parking zones. Signs should be spaced along the entire fire lane so that any motorist will know that parking in that area is not allowed. While it is common sense to keep fire lanes free of vehicles, in many cities it is the law that fire lanes be marked on the pavement, but they must also include âNo Parking" signs as a secondary marking. Please check your local or state laws for details.
