How long the B license lasts by age

The B license lasts 10 years until age 50, 5 years from 50 to 70, 3 years from 70 to 80, and 2 years after 80. It is renewed with a passed medical exam (just one even for A and B), not with a driving test.

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