check your location from the marker posts on the left
The emergency services need to know your exact location so they can reach you as quickly as possible. Look for a number on the nearest marker post beside the hard shoulder. Give this number when you call the emergency services as it will help them to locate you. Be ready to describe where you are, for example, by reference to the last junction or service station you passed.
B stand at the rear of the vehicle while making the call
C try to repair the vehicle yourself
D get out of the vehicle by the right-hand door
