When will the warning light be used on its own in a priority vehicle?
Right of way
Explanation
**Priority vehicles**, such as police cars, fire trucks, and ambulances, are equipped with **blue lights** and sirens to indicate that they are on an **urgent service**. These lights are used to alert other drivers and pedestrians of their presence and need for priority passage.
- **Use of lights and sirens**: When a priority vehicle is on an urgent service, it must activate both the lights and the siren. This grants them preference on all roads, and other drivers must yield to them.
- **Conditions of use**: The lights can be used in isolation, that is, without the siren, only if it does not endanger other drivers. This is important to avoid confusion or risky situations in traffic.
- **Safety**: Although they have preference, the drivers of these vehicles must ensure not to endanger others when crossing intersections or ignoring red traffic lights. The safety of all road users is paramount.
Therefore, the light signal is used in isolation on a priority vehicle **in urgent service if it does not endanger other drivers**.
