How many meters to leave at each speed

The faster you go, the more space you must leave. At 30 km/h about 9 meters, at 50 about 14, at 100 about 28, at 130 about 36, at 150 about 42 meters.

A few meters (2, 5, 15) are never enough.

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