Minimum speeds for each lane

On the motorway it says the minimum speed of each lane: the slower you go, the more you stay to the right. Someone going 50 km/h stays in the first lane on the right; someone going 100 km/h can stay in the middle one.

Word: Velocità minima = the lowest speed you must keep.

The exam is in Italian: key terms and trap words are kept in Italian, so you learn them.
