> We had a tyre blow out on a motorway in Scotland All UK motorways have location signs posted every 500m (coupled with distance marker posts at 100m intervals) that are specifically designed so drivers with breakdowns can report their position...... not to mention the (free) orange SOS landline phones every 1 mile which, if used, will automatically report your position. (a little arrow on the marker post points to the nearest SOS phone; you are never more than half a mile from one). You had to learn this for your driving test :-) https://en.wikipedia.org/wiki/Driver_location_sign https://en.wikipedia.org/wiki/Driver_location_sign EDIT: My mistake, only England has adopted the driver location signs. The rest of the UK makes do with the distance marker post system (and SOS phones if needed).
