Looking at you

Glance not a trance
If you are driving on the main road and a vehicle is coming from a minor road in front of you, we need to see if they are looking at us.

If they are then it is very good sign that they have seen us and we can see that they are going to be more aware of where we are.

If they are not looking at us then it is a sign that we need to be ready to take evasive action.
