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

To call an ambulance, you can dial two emergency numbers: 999 or 112. The number 999 is a direct connection to the medical dispatch centre, while 112 is the pan-European emergency number that will forward your call to the appropriate services. Dialling either of these numbers is correct and will allow you to effectively summon help.
