A Swiss organisation representing road accident victims and their families has collected enough signatures to force a vote on tougher laws for speeding drivers.
Members of RoadCross handed their initiative - signed by 106,000 people - to the Federal Chancellery in Bern on Wednesday.
The initiative would keep speeding drivers off Swiss roads by means of revoked licences and prison sentences, with higher penalties for those who cause accidents resulting in death or serious injury.
The initiative has the backing of a number of parliamentarians on both the left and right.
Parliament is also considering a government proposal to make Swiss roads safer. The Via Sicura package includes some measures which crack down harder on speeding drivers and on those caught drink driving.
Over the past decade the number of deaths in road accidents has dropped by 40 per cent; there were 349 deaths in 2009, and 4,708 people were seriously injured.
