Your vehicle breaks down on a motorway and you need to call for help. Why might it be better to use an emergency roadside telephone rather than a mobile phone?

Explanation: On a motorway, it's best to use a roadside emergency telephone so that the emergency services are able to find you easily. The location of the nearest telephone is shown by an arrow on marker posts at the edge of the hard shoulder. If you use a mobile, find out the number on the nearest marker post before you call. This number will let the operator know where you are and in which direction you're travelling.
