Germany

Adults in Germany may carry up to 25g of cannabis in public and keep 50g and grow up to three plants at home, but there are still no recreational shops and buying or importing cannabis commercially remains illegal.

Commercial sale and import remain illegal; possessing over 30 g in public (or over 60 g at home) is a criminal offense.

Entering or leaving Germany to/from a non-EU country with €10,000+ in cash (incl. banknotes, securities and gold) must be declared in writing to German Customs.

Failure to declare is an administrative offence — fine up to €1,000,000.

Seat belts are mandatory in both front and back seats, and children under 12 may not ride in the front and must use a child safety seat.

EUR 30 fine; an accident with belts unfastened can invalidate your insurance.

Most major German cities have low-emission zones (Umweltzonen) you may enter only with a green Umweltplakette emissions sticker displayed on the windscreen.

About €80 fine for driving in a zone without a valid sticker.

Germany's blood-alcohol limit is 0.5 mg/ml (0.05%) for standard drivers, but there is a total alcohol ban (0.0) for novice drivers in their probation period, drivers under 21, and professional drivers.

Over the limit brings fines and licence withdrawal; from 0.3 mg/ml you can be penalised if your driving is impaired or you crash.
