Answer 1

In France speed limits are set according to the road type. Except if indicated otherwise, cities are limited to 50, common roads are 80 if it’s two way traffic, 90 if it’s split up traffic, roadways are 110 and highways are 130.

According to the section R413-8 of the “code de la route” you have different speed limits according to what you transport, and you have to have them displayed in he back to let other drivers know. For buses it varies depending of it’s a city bus or a seated bus. For trucks it’s 90 on the highway or on roadways and 80 on common roads. Transport dangerous goods and it falls to 80max on roadways and highways, and 60 on common roads. And there are subsets of those rules, the limit that applies is always the below
(if the road is limited to 90 and you have a truck with an 80 and a 110, it should drive at 80 etc)

Edit : truck speeds.
