After Kivilev's death, the UCI made the wearing of helmets compulsory. They had previously tried to introduce this requirement in 1991, but some riders protested this at the Paris–Nice race, so the rule was not introduced. The nature of Kivilev's death, in that he was a lead rider, in one of the top French cycling teams, racing in a top stage race, coupled with advances in helmet technology, brought the debate back to the fore and conclusively so for the UCI. Whilst many riders were initially still against compulsory helmet use, the UCI ensured the rules requiring helmets to be worn at all times would be in place for the 2003 Giro d'Italia, which started just eight weeks after Kivilev's death. Dissension to the rule was initially high, but the new rules were affirmed in October 2003. Whilst at first the rule was loose and not tightly enforced, especially on mountain-top finishes, it has since been enforced more strictly and helmet-wearing is now universal and uncontroversial in the peloton of both professional as well as amateur races. It has also become common-place among recreational riders in many parts of the world.
