New Orleans officials have banned tandem floats from parading during the rest of the Mardi Gras season after two people were killed in separate accidents last week. Both incidents -- one on Saturday and the other on Wednesday -- involved tandem floats, which have two or more floats connected together by a hitch and pulled by one tractor. NOLA Ready, the city’s emergency preparedness campaign, and Mayor LaToya Cantrell announced tandem floats won’t be allowed for the rest of the season. The Endymion parade is one of the most popular and one of the most family-oriented parades leading up to Mardi Gras, which is Tuesday. That incident followed a Wednesday fatality when a woman was hit with a tandem float during the Krewe of Nyx parade.
