Normally, how far apart are emergency telephones on a motorway?

Explanation: Emergency telephones on the motorway are connected to control centres, where the operator can identify your location from the telephone you're using. To help you locate an emergency telephone, marker posts are situated at 100 metre intervals. These marker posts have arrows directing you to the nearest telephone. Emergency telephones are spaced at 1 mile intervals.
