The **maximum permitted blood alcohol level** for a bicycle rider is **0.25 milligrams per liter of exhaled air**. This limit applies to any vehicle and driver not in special categories, such as novice drivers or those transporting dangerous goods, people in emergency services, or more than nine people. For these special cases, the limit is lower, at 0.15 milligrams per liter of air.

It is important to remember that, although the law allows certain amounts of alcohol, the only completely safe blood alcohol level for driving is **0.0**, meaning not consuming alcohol at all. Alcohol negatively affects the brain and vision, increasing the risk of traffic accidents. Therefore, it is always better to avoid alcohol consumption if you are going to drive any type of vehicle, including a bicycle.
