No parking sign board is a road safety sign that is used to prohibit or restrict the parking of vehicles on a certain road or area. The standard No Parking sign board comes in a rectangular shape with a red background and a white border and can be tailor-made to meet specific requirements. It also has a white symbol of a crossed-out letter P and a white text that specifies the condition or the duration of the prohibition or restriction, such as no parking anytime, no parking from 8 a.m. to 6 pm, etc. No parking sign board is necessary to prevent the obstruction or congestion of traffic.
