For drivers who have obtained their **driving license less than two years ago**, the maximum permitted blood alcohol level is **0.15 milligrams of alcohol per liter of exhaled air**. This restriction is stricter compared to other drivers due to the lack of driving experience, which can increase the risk of accidents if alcohol is consumed.

In contrast, for more experienced drivers, the permitted level is **0.25 milligrams per liter of air**. However, for novice drivers, exceeding the 0.15 milligram level can result in penalties, such as the loss of points on the driving license. For example, if a novice driver has a blood alcohol level between 0.15 and 0.30 milligrams per liter of air, they will lose 4 points from their license.

Therefore, it is crucial that novice drivers are aware of this limitation to avoid penalties and, more importantly, to ensure their safety and that of others on the road.
