Which of the following numbers should you call in order to call an ambulance to the scene of a road accident?

Why?

Call 999 to reach a medical dispatcher directly, or use the general emergency number 112 to request an ambulance. The phone displaying an ambulance illustrates a call for emergency medical assistance. The numbers 997 and 998 are traditionally assigned to the police and fire service, so 112 or 999 is the correct pair in this question.
