What is the maximum permitted blood alcohol level for a bus driver?
Human factor: Alcohol, drugs, and medications
Explanation
The **maximum permitted blood alcohol level** for a bus driver is **0.15 milligrams per liter of exhaled air**. This is because buses are vehicles that transport more than nine people, and for this type of vehicle, the regulations establish a stricter blood alcohol limit.
- **Bus drivers** and other vehicles that transport heavy goods, minors, or people in emergency services have a limit of **0.15 milligrams per liter of air**.
- In contrast, for other drivers and vehicles, the limit is **0.25 milligrams per liter of air**.
It is important to remember that, although there are legal limits, the only completely safe blood alcohol level for driving is **0.0**, meaning not consuming alcohol before driving.
