How do traffic light controlled junctions that have filter systems work?
I understand the general concept of traffic light controlled junctions that have the green arrow filter system . That if the green arrow on the traffic light is pointing the direction you wish to go then you have priority over other traffic and that , for instance if you wish to turn right and there is a green light circle instead of an arrow then you can go unless oncming traffic is preventing you . However , in the instance where you wish to turn right , and there is green light instead of an arrow and there is oncoming traffi , so you approach the marked are in the middle of the road for turning right . Then before you are able to turn right due to the oncming traffic , the light turns to red , do you wait in the middle of the road for there to be a green light or arrow , or do you go when the light turns red , because otherwise you will be blocking traffic ?
if you pass on green and then they change,you are in the wrong if involved in a crash..
