FRANCE YELLOW VETS PROTESTS
Why do they have all these yellow vests?
Because in France you are required to have a yellow vest in your vehicle.
You must also carry a warning triangle and have headlamp beam deflectors.

The movement originated with French motorists from rural areas who had long commutes protesting against an increase in fuel taxes, wearing the yellow vests that, under a 2008 French law, all motorists are required to keep in their vehicles and wear in the case of an emergency.
