Our county 911 actually asks the civilians to stop.

Unfortunately, many people want to dial 9-1-1 from their cellular telephone, but then cannot or will not answer the questions that are asked by the emergency call taker. Dozens of cellular 9-1-1 calls are often received for the same vehicle accident. This can overload the 9-1-1 system. Please remember the following rules for cellular 9-1-1 calls:
- Do not dial 9-1-1 if you are unable or unwilling to give an accurate location of the incident.
- If you truly want to help, stop and collect the following information.
Are there any injuries? If so, how may people have injuries? This information will determine the number of ambulances to be dispatched.
How many vehicles were involved? This information is required by the police.
- If the incident has occurred at a busy location, and you are not willing to stop, please don't tie up lines dialing 9-1-1. Let someone call who is willing to stop. If the incident is at a remote location where you may be the only caller, then you should call even if your are unable or afraid to stop.
They don't stay stop and use your EMT skills or first aid or anything like that. They are simply saying stop so that they can dispatch the call appropriately.
