Is it true that unless otherwise posted, a speed limit of 100 kilometers per hour applies to all vehicles on roads in Germany?

The statement is false. In Germany, the general rule regarding speed limits is that unless specified otherwise, different speed limits apply based on the type of road and the type of vehicle. While it is true that there are sections of the autobahn (motorway) where there is no formal speed limit for cars, other types of roads, such as urban areas and rural roads, have specific speed limits, often lower than 100 kilometers per hour. For example, urban areas typically have a speed limit of 50 kilometers per hour, and specific regulations may also apply to vehicles like trucks, which may have lower speed limits than passenger cars. Therefore, the statement oversimplifies the speed limit situation in Germany by suggesting a blanket limit of 100 kilometers per hour without acknowledging the nuances based on vehicle type and road conditions.
