Abstract: A markable sign is characterized by a laminated structure comprising a flexible layer of backing material having a front surface for receiving permanent printing and a rear surface for mounting on a support object. A flexible transparent layer has a rear surface for receiving permanent printing and a front surface. The transparent layer is connected with the backing layer with the rear surface of the transparent layer preferably being in contiguous relation with the front surface of the backing layer. The front surface of the transparent layer includes two coated areas, one for receiving a permanent marking and the other for receiving an erasable marking. When the sign is mounted on a motor vehicle, information regarding specifications for the vehicle are applied in the form of permanent markings to the first coating and information regarding maintenance performed at regular time intervals can be applied in the form of erasable markings to the second coating.
