Correction: 3 October is a public holiday in Germany — a Saturday with a full-day ban, not a free Saturday
The article on the 3-4 October weekend, published on 18/09, said "no special holidays" — but 3 October is Tag der Deutschen Einheit, Germany's national holiday, which falls on a Saturday this year. That triggers the holiday ban from 00:00 to 22:00 on that day, instead of the usually free Saturday outside the summer season.
The article «Weekend 3-4 October: heavy goods vehicle driving bans in Europe», published on 18 September, stated that this weekend has no national holidays that would trigger extra restrictions in Europe. That information is incorrect for Germany.
What changes
3 October is Tag der Deutschen Einheit (German Unity Day), a national holiday throughout Germany. This year it falls on a Saturday — and a German public holiday always triggers the same ban as a Sunday, from 00:00 to 22:00, regardless of which weekday it falls on. It is therefore not a free Saturday like the rest of October’s Saturdays: it is a full driving ban for goods vehicles over 7.5 tonnes across the entire network, end to end.
Anyone planning to cross Germany that Saturday should treat it exactly like a German Sunday: leave before 00:00 on Saturday or wait until 22:00 to resume the journey. The following day’s Sunday ban, 4 October, applies on top as usual, from 00:00 to 22:00 — meaning there are, in practice, two consecutive full-day bans, Saturday and Sunday, with only a free window between 22:00 on Saturday and midnight on Sunday.
