Right of way
Explanation
**Police cars** are vehicles that perform **emergency services**. To indicate their priority in traffic, they use a **blue flashing light**. This blue light is a common feature of all emergency vehicles, such as fire trucks and ambulances, which can also use it along with a siren to alert other drivers and pedestrians of their presence and need for passage.
When these vehicles are on urgent duty, they have **right of way** on all roads, and other vehicles and pedestrians must yield to them. This allows them to quickly reach their destination to attend to emergencies.
