The **maximum permitted blood alcohol level** for driving any vehicle, in general, is **0.25 milligrams of alcohol per liter of exhaled air**. This is the amount of alcohol that can be present in the air we exhale after consuming alcohol.

- This limit applies to most drivers and vehicles. However, there are exceptions for novice drivers (with less than two years of experience) and for certain types of vehicles, such as those transporting heavy goods, more than nine people, minors, people in emergency services, or hazardous loads. For these cases, the permitted level is lower, at 0.15 milligrams per liter of air.

- It is important to remember that, although these are the legal limits, the only completely safe level for driving is **0.0**, meaning not having consumed any alcohol at all. This is because alcohol affects the ability to drive safely.

- Additionally, driving with a blood alcohol level between 0.25 and 0.50 milligrams per liter of air can result in the loss of points from the driving license, which underscores the importance of respecting these limits to avoid penalties and ensure road safety.
