Two-lane expressway

A dual carriageway ( known colloquially as freeway or expressway ) is in Germany a public road which is intended for such vehicles, whose maximum design speed exceeding 60 km / h and a maximum of four meters high and 2.55 m ( refrigerated vehicles 2.6 m ) wide (§ 18 Highway Code Highway Code ).

Motor roads are not the same roads in other countries; the sign 331.1 and 331.2 are rather used in applications where fast cars should operate. Conversely, not all roads that meet the traffic- purpose auto roads posted as motor vehicle road. This is for example in the range of larger bridges (example: Rhine bridge Maxau ) the case to allow even slower vehicles such as tractors crossing the bridge.

On motor roads the usual speed limits apply in accordance with § 3 Highway Code, unless appropriate signs Arrange a higher or lower speed limit. On multi-lane motor roads, the carriageways are physically separated from each other, may - unless this limits a traffic sign - such as on highways " are driven so fast that can be held within the managable route ". Such unrestricted motor roads there are, for example, in space Flensburg, in the southern Harz on the B27 and on the feeder from the A81 to Konstanz on Lake Constance, where even on long stretches.

For trains trucks with trailers, motorcycles and buses speed limits for highways as applicable according to § 18 of Road Traffic Regulations, unless the carriageways are structurally separated.
