Gents, I thought I start this as I am driving almost every week to France, Germany and Italy. New Euro emission rules are now in place all over Europe and more to come before the end of 2019. You MUST display a sticker or face heavy fines, car impounded or more legal complications - not what we all want. You can buy your Sticker here : https://www.umwelt-plakette.de/en.html ^^^this is for All areas in Europe. There are apps too so please have these handy. In France : https://www.certificat-air.gouv.fr/en/ Please buy and display these before you travel to Europe and check all areas where you will be driving: motorways, city centres. In some cases (ie France - proof of payment accepted). Also in France and Germany new speed laser guns are fitted from January 2019. DO NOT even dare to go over by 20 km/hr unless No speed limit sign is clearly displayed. Also apply for an IDP (international driving licence) as the French Police are ready to fine you 300€. I have one and I was asked show it. Trust this helps everyone. Drive safe!
