Approach road junctions with great care, consider your road position and your speed, drive on only when you are sure it is safe to do so and that you will not block the junction, watch out for long vehicles which maybe turning left or right, at the junction ahead, but which may have to use  to make a turn, when waiting to emerge at a junction, do not assume that a vehicle approaching from the right which is signalling with it's left hand direction indicator would turn left, wait to make sure  do you know what I mean?
