Saviez-vous que le premier feu rouge à Paris était bleu? Apprenez l'histoire insolite de ce feu expérimental installé place de l'Opéra dans les années 1920.

## L'histoire insolite du premier feu rouge à Paris Si vous traversez la place de l'Opéra aujourd'hui, les signaux de circulation vous semblent évidents. Pourtant, le premier feu de signalisation installé dans la capitale durant les années 1920 n'était pas du tout ce à quoi on pourrait s'attendre. À cause d'une pénurie technique assez particulière, la ville a dû improviser avec les moyens du bord, créant une confusion totale chez les automobilistes et les piétons de l'époque. ### Ce que vous allez apprendre sur ce vestige urbain * Pourquoi la ville a utilisé une ampoule bleue au lieu du rouge habituel.
* La réaction imprévisible des Parisiens face à cette nouvelle couleur.
* L'emplacement exact où cette expérimentation a débuté en plein cœur de Paris.
* Le contexte historique de la signalisation routière dans les années 1920. Cette anecdote montre comment une simple contrainte matérielle a failli changer les codes de la route que nous utilisons encore aujourd'hui.
