islandgem... the sign the OP is questioning is not a sign warning of electrocution... It is a sign that is part of a sensibilization campagn regarding deadly sccoter and motorbikes accident, and they are placed where someone lost the life, all over the territory of french St Martin.. the same signs also exist all over France. They are made by the collectivity, or different government organism. It is not a commercial sign like MarcG shown in his link. <img src="http://www.traveltalkonline.com/forums/images/graemlins/duh.gif" alt="" /> <img src="http://www.traveltalkonline.com/forums/images/graemlins/handshake.gif" alt="" />
