For a driver who has just obtained their first driving license, the permitted blood alcohol level is **0.15 milligrams of alcohol per liter of exhaled air**. This is because novice drivers, that is, those who have had their driving license for less than two years, have stricter restrictions regarding alcohol consumption.

- The regulations establish that these drivers must maintain a lower blood alcohol level to ensure road safety.
- In comparison, more experienced drivers can have a level of up to 0.25 milligrams per liter of air, but novices must adhere to the lower limit of 0.15 milligrams.

It is important to remember that, although these are the permitted levels, the only completely safe level for driving is **0.0**, meaning not consuming alcohol before driving.
