Most countries lifted their racing bans within a year after the disaster. France in particular, as the host of Le Mans, lifted their complete ban on 14 September 1955. On that date, the French Ministry of the Interior released new regulations for racing events, and codified the approval process that future racing events would need to follow. In contrast, Switzerland's ban, which also extended to the running of timed motorsports such as hillclimbs, was not quickly lifted. This forced Swiss racing promoters to organize circuit events in foreign countries including France, Italy, and Germany. In 2003, the Federal Assembly of Switzerland started a lengthy discussion about whether this ban should be lifted. The discussion focused on traffic policy and environmental questions rather than on safety. On 10 June 2009, the "Ständerat" (upper house of the Swiss parliament) defeated a proposal to lift the ban for the second time. In 2015, the ban was relaxed for electric vehicles only, such as cars involved in Formula E electric racing.
