How the test works on the computer
For the A1, A2, A, B1, B and BE licences, the theory test is on a computer. 30 statements appear on the screen, that is sentences that can be true or false. For each one you must choose between True and False.
The time you have is 20 minutes. You pass the test with at most 3 wrong answers. These rules apply to the patente B exam and to the other licences listed above.
Where you see the result
The exam results are published on the Portale dell'Automobilista, the website of public services for people who drive.
To see your result, you must be a registered candidate on the portal or log in with SPID (Sistema Pubblico di Identità Digitale), the digital identity that you use to enter the online services of public administrations.
If you do not pass the test: how many times you can try again
You must pass the theory exam within 6 months of the licence application, that is from when you submit the request to start the process. In this period, at most 2 attempts are allowed (Codice della strada, art. 122).
If you do not pass the first attempt, you cannot try again right away. At least 1 month must pass between an exam attempt that you did not pass and the next one (Codice della strada, art. 121).
Also remember that you must book an exam at the latest 5 days before the date of the test (Codice della strada, art. 121). To book means to fix the day of the test in advance.
How to practise for the patente B theory

- Read each statement calmly: a single word can change the meaning of the sentence.
- After each simulation, review the wrong answers and read the explanations.
- Practise regularly, instead of putting everything into the last days.
