For **novice drivers**, that is, those who have obtained their driving license less than two years ago, the **permitted blood alcohol level** is **0.15 milligrams of alcohol per liter of exhaled air**. This is stricter compared to drivers with more experience, who can have a level of up to **0.25 milligrams per liter of air**.

Once a novice driver has had their driving license for **two years**, they are no longer considered novice and can drive with the higher blood alcohol level permitted for experienced drivers, which is **0.25 milligrams per liter of air**. Therefore, a novice driver can drive with this blood alcohol level only after having had their license for two years.
