All applications for a disabled parking permit require a physician's certification. The certifying physician must indicate the expected length of disability. The temporary permit may be renewed if the physician certifies an extension of the disability. Permanent permits, placards or metal plates, are available for citizens with a disability which, in the physician's opinion, will not improve. Permanent permits are valid for five years and may be renewed.
