!caution when !chase has ended?

[SO•Marty]

I was just wondering this, maybe this could be implemented for more safety.
When a chase has ended, the sirens visible on the track go away immediately. Often, the suspect and police are still on the road standing still.
If the chase has been ended because of the suspect crashed heavily, the chase could be standing still in a dangerous position.
Is it an idea to change the !siren into a !caution automatically when a chase has been stopped and the suspect and cops are standing still in the road?

It means the drivers around the ended chase still have to be cautious on cars that are standing still.
Once the cars are driving again, the !caution could be ended automatically.

Is this an idea or can I walk to the garbage can with it?

Greets,
