From January 1, 2016 is also on the engine in France for driver and passenger are required to have a CE-approved reflective vest with him. It is then obliged to raise this as a rider or driver of a tricycle if you are outside built-up areas is to consider a non-functional motorcycle / tricycle or in an emergency stop for another reason.
The penalty for not having with him a fluorescent vest with € 38 certainly not high, but an emergency can provide more cost; for it not to have the safety vest the fine can -as additional Breakdown rise up to 750 Euros! Moreover, this rule also applies to cyclists and drivers of a wheelchair. Cars are still the familiar warning triangle and an alcohol test, but the latter two do not apply to motorcyclists.
As always and everywhere reigns subjectivity and emotion over rational.
It is not always true that more striking with a yellow cardigan.
This is the contrast that you have with the environment. It’s a hell around, summer day, lots of light; you fall right in with dark clothing. And most motorcyclists ride in good weather and when it is light.
Neither in low light trap you neither are your clothes nor with what color, is you seen as your clothes reflect light. So the best thing is normal dark motorcycle with lots of reflective surfaces.
But unfortunately, as usual, take the political decisions that are totally not related to the actual fact.
