Right turn on T-junction with traffic lights

    Sorry i know this is probably a bi of a stupid question but i would appreciate any help people could offer (I really don't fancy failing my test again)

    If you are at the "top" (the straight part) of a T-junction and are turning right. If you have a solid green light (no filter light) and you are in the right line to turn right and there is sufficient room behind the first car to proceed into the junction are you allowed to? i know the rules of the road says you're supposed to proceed into the middle of the junction but i'm not sure if you should when you're not the first car because there seems to be potential for you to block the junction creating an obstruction.

    Sorry if this isn't that well explained but it's the best i can do i'm afraid.

    Thanks

    If there is already a car waiting to complete the turn, then you wait behind the stop line.
    If the 'first' car (ie not you) makes the turn, and the lights are still in your favour, then you move forward into position and if it is safe, complete the turn.
    Should the light turn amber while you are waiting to complete the turn, and you have already moved beyond the stop line, do not panic - you can complete the turn. There is a slight delay between your lights turning red and the light going green for the other traffic - this gives you the time to complete the manouevre.
    Once you have proceeded beyond the stop line, you are committed to completing the turn.
    If you are the first car, and waiting for an opportunity to make the turn, check the road you are turning into, to see what potential hazards you might meet.
    Depending on the junction, there may be a box marked for right turning traffic, or a noticeable area where a sensor is located. At some light controlled junctions, the filter light is activated by a weight pad, or IR sensor, and when the car is in the correct position, the filter is activated. You may notice where pads are by a tar seal on the road.

    picture this solid green light, you want to go right. There is only one lane of traffic and you are just left of centre(against the white line in centre of raod) you are second in line and you stay behind line, ask yourself can the traffic behind you move forward, can they go straight and turn left. If the answer is no then you have to follow the first car into the centre of the road. remember you do not want to be marked for being hesitant, the changes are that after that solid green light a filter light will follow and you will have plenty of time to turn.
    Best of luck on the test,
    where are you taking it

    I think tc20 summed it up pretty well - good advice there.

    This is not such good advice :

    Assuming you have taken up the correct position on the road (i.e. just left of center line) it doesnt matter what the traffic behind is doing - you do NOT need to move out of their way and you will not be marked for being hesitant in that situation. If there is a car in the center of the junction already then hold your position behind the STOP line.

    I would say this is a local junction situation and if so get a lesson from an instructor in that area and they will be able to explain the junction for you.

    In normal cases you would move into the centre of the junction and once the road is clear, turn.

    If you have more than one car turning Just make sure that you will have the room in your intended destination/lane when you try to turn, so that you will not end up blocking the lane of the oncoming traffic.

    Regards

    Regardless of the delay between the lights, the other traffic can only proceed if their way is clear and it is safe to do so - something which seems to escape the minds of many drivers with a green light.

    (When I'm driving large vehicles I sometimes find myself trying to complete a right turn manoeuvre into a narrow road while the lights have gone green for the other traffic. They sometimes sound their horns but what do they expect me to do- make the trailer disappear?)

    I agree with DriveSkill - that's poor advice. The vehicles following must wait.

    Of course you're absolutely correct WA. Personally i would do this from experience, but should have made it clear in my reply to the OP.

    Remember the yellow box rule - only one car at a time. The same logic applies to turning at junction. Wait behind the stop line (ignoring any beeping idiots if needs be) until you can proceed into the junction. Otherwise you could get caught in the junction and block oncoming traffic when the lights change.

    Thanks again.
