Double yellow lines give us less room to park. Why have them?
Yellow lines will not reduce the amount of safe parking spaces available, they will simply make it clearer where it is or is not safe to park. Double yellow lines will delineate areas where parked cars could cause danger, for example at junctions or where parked cars cause an obstruction. Clear junctions are safer for drivers and pedestrians and allow cars to turn safely and pedestrians to cross safely.
