   (a)   (1)   Off-premises signs will be allowed a maximum size of 288 square feet except as permitted in § 160.592.

   (f)    Similar to basics of measuring of this code, all distances will be measured from the closest point of any part of the sign. The sign shall not be within a 600-foot radius of any other off-premises sign intended to be read from the same right-of-way; the sign shall not be within a 600-foot radius of any other off-premises sign intended to be read from a different right-of-way; the sign shall be no closer than 600 feet from any existing off-premises sign on an interstate highway. 
   (g)    Off-premises signs shall be maintained in a safe and legible condition at all times, including the replacement of defective or damaged parts, painting, repainting, cleaning, and other services required for maintenance of the signs. Unsafe signs shall be removed immediately or brought into compliance upon written notice.
