Autobahns of Austria
Unlike German autobahns, on Austrian autobahns a general speed limit of 130 km/h (81 mph) is set, although as of August 25, 2018, the FPÖ government has been going on a trial for a possible speed limit increase to 140 km/h (87 mph) on the Autobahn 1 freeway. They may only be used by powered vehicles that are designed to achieve at least . While on the motorway voluntary stops, U-turns and backward driving are prohibited.
Speed limits in Germany
Posted minimum speeds usually only apply to specific lanes like the common configuration on 6-lane roads with a minimum speed of 110 km/h (68 mph) on the left and 90 km/h (56 mph) on the center lane. Vehicles which cannot sustain speeds of 60 km/h (37 mph) on the flat are not allowed on the Autobahn, however. Because of this, many European self-propelled cranes and other extra-heavy trucks which would be unsafe at much higher speeds, but similarly unsafe or impractical (and certainly obstructive) to drive for long distances on surface streets between job sites and depots, are engineered with maximum design speeds a little over 60 km/h - typically 62 km/h (39 mph) at governed engine speed in top gear.
