The last stop sign in Paris was located at the 16th arrondissement and disappeared in 2015.

French car owners seem to manage well without stop signs, knowing only one important rule: priorité à droite. All drivers in France know and follow this rule. The priorité à droite rule dictates how drivers must react when approaching an intersection. They must cede the way to drivers coming on the right. Drivers on the right always have the priority. Drivers coming from the left must slow down and let drivers on the right proceed through the intersection.
