When you use the emergency telephone on a motorway, you should face the oncoming traffic while using the phone. This position helps ensure you can see other vehicles approaching and remain aware of any potential dangers. It is also advised to stand on the hard shoulder but keep safe by staying away from passing traffic. Additional safety tips include leaving your vehicle by the left-hand door, wearing a high-visibility vest if you have one, and standing behind any safety barriers if present once your call is complete. This positioning helps keep you safe while you communicate with emergency services.
