Tour de France organisers threw a television car off the race after it sent two riders flying across the road on a crash-marred ninth stage.
The car hit Team Sky's Juan Antonio Flecha as it overtook, while Dutchman Johnny Hoogerland fell into a fence.
"They caused the crash of both riders. This behaviour is intolerable," said Tour director Christian Prudhomme.
Frenchman Thomas Voeckler took the leader's yellow jersey after the stage, won by Luis-Leon Sanchez.
