New Orleans has banned so-called tandem floats for the remainder of its Mardi Gras celebrations this year after two people were struck and killed by such floats in a four-day span.

Mayor LaToya Cantrell announced the ban on Saturday night, after a man was struck by a float just before 7 p.m. as the Krewe of Endymion parade made its way along South Galvez and Canal Streets. Tandem floats are multiple floats connected by a hitch and pulled by one tractor.

The New Orleans Police Department said that the only exceptions to the ban would be “large floats that require generators to light the float.”

The name of the victim, who was pronounced dead at the scene, was not immediately released. WDSU-TV, an NBC affiliate, reported that the man might have been reaching for beads when he was dragged under the tandem float, No. 13.
