**Priority vehicles** such as police cars, fire trucks, and ambulances have certain advantages when they are on an **urgent service**. They can drive faster and are not required to follow all traffic signals. However, they must **ensure not to endanger others**.

- At **intersections**, these vehicles must be careful not to violate the **right of way** of other vehicles or pedestrians. Although they have preference, they must act in a way that does not cause accidents or dangerous situations.

- The only exception to traffic rules for these vehicles is that they must obey the **instructions of traffic officers**. This ensures that, even in emergency situations, traffic remains safe and orderly.


In summary, although priority vehicles have certain freedoms in emergency situations, they must be responsible and careful, especially at intersections, to not compromise the safety of other road users.
