Germany
Cap in the app: 80 km/h.
Speed
80 km/h outside built-up areas and on the Autobahn. A Tempo-100 plate gives 100 on the Autobahn. § 3 does not apply to the Autobahn — that figure comes from § 18 Abs. 5, which must be cited separately.

| Dimension | Germany |
|---|---|
| Width, general | 2.55 m |
| Width, passenger car | 2.50 m |
| Height | 4.00 m, applies to all vehicles, combinations and trailers |
| Length, individual vehicle and individual trailer | 12.00 m (Abs. 3 Nr. 1) |
| Length, car with caravan | 18.00 m (Abs. 4 Nr. 3 a) |
The passenger-car row is worth noticing: 2.50 m, not 2.55 — and it applies only to the car. The caravan is an Anhänger and falls under the general row of 2.55 m. The outfit may therefore lawfully be wider at the back than at the front, which is the opposite of the Danish rule (trailer at most 0.35 m wider).
The length question is now settled, and the answer is the lower of the two figures. Abs. 4 divides Züge into points, and point 3 expressly excepts point 4:
bei Zügen, ausgenommen Züge nach Nummer 4: a) Kraftfahrzeuge außer Zugmaschinen mit Anhängern 18,00 m, b) Zugmaschinen mit Anhängern 18,75 m
Point 4 is a lorry with a goods trailer (18.75 m) and point 3 b) is a Zugmaschine, a tractor unit in the agricultural sense. A car with a caravan is neither one nor the other but a Kraftfahrzeug außer Zugmaschine mit Anhänger — point 3 a), 18.00 m. The most-quoted figure, 18.75, is therefore wrong for this particular outfit, by 75 centimetres.
