国別のチャイルドシート規則

多くの国は子どもがある年齢・身長・体重に達するまでチャイルドシートを義務付けています。最大の違いは後向き乗車の期間です。スウェーデンは約4歳、多くの地域は15カ月までの助言にとどまります。渡航前に現地の法規を確認してください。

前向きハーネス席を卒業後、通常4歳ごろから、車のシートベルトが合うまで(多くは8〜12歳か145cm)。
国によって本当に違う?
はい、大きく異なります。身長の目安は135cm(英国)から150cm(独・仏)、後向きは15カ月から4歳までさまざまです。
子どもは後部座席が必須?
多くの国で後部が最も安全で、幼児には法的に求められます。一部(仏など)は後部が空けば10歳未満の前席を禁じます。
