Traffic Roundabout

Normal Roundabouts

Traffic Roundabout

When approaching a conventional roundabout, where there are four roads con¬verging in the same manner as at a crossroads, you should normally approach the roundabout in exactly the same manner, as that in which you would have approached a crossroads, if the roundabout had not been there. Other than in situations, where there is a number of other vehicles directly in front of you, where you must pay particular attention to the other drivers actions, you should start to take observations to the right as early as possible, to enable you to judge the speed and distance of other road users who are already travelling round, or who will have joined the roundabout before you have reached the give way line at the entrance to the roundabout. You should reduce the road speed of the car, in accordance with the curvature of the roundabout, or the volume of traffic on the roundabout, before selecting the appropriate gear, which on a larger roundabout, would normally be third gear, provided that it is safe to proceed. Whereas with smaller roundabouts you may require a lower gear such as second gear, and if you have to come to a complete stop, naturally it would be necessary to select first gear. Once clear, particularly on larger roundabouts, where the curve and the amount of steering required has been minimal, then it is important to remember that you must cancel the left signal, as in such instances, due to the small amount of steering required, it is unlikely that the cancelling device will have come into operation.

Turning Left

On the approach, you should check the interior and nearside door mirrors, then whenever it is safe to do so, move the direction indicator to operate a left turn signal and if you are not already in the normal driving position, or where an additional left turn lane has been added, you should move into the left hand lane. Having joined the roundabout, you should maintain your position in the to lane and maintain the left turn signal, until such times as you have completely cleared the roundabout.

Going Ahead

on the approach, you should check the interior mirror, and where you are already in the normal driving position, you should approach in the left hand lane, when there are only two lanes available on the approach. Where there are three lanes on the approach, you should again remain in the left lane, other than in circumstances where the left lane is marked with lane arrows indicat¬ing that this is a left turn lane, in which case, having checked the mirrors to see that it is safe to do so, you should take up a position the middle lane of the three. In this instance no signals are required on the approach. Having joined the roundabout, you should maintain your position in whichever lane you have chosen to enter the roundabout, until such times as you have reached a posi¬tion, where you have driven past the exit of the road, before the one which you intend to leave by, at which times you should check both the interior and left door mirrors, before giving a left turn signal to leave the roundabout by the next exit. You should retain the left turn signal, until such times as you have completely cleared the roundabout.

Turning Right

On the approach, you should check the interior and offside door mirrors, then whenever it is safe to do so, give a right turn signal with your direction indicator, and where you are driving along in the normal driving position, you should then move across into the right hand lane, irrespective of whether there are two or three lanes on the approach. Where there are three lanes, you should only move across one lane at a time. Having joined the roundabout. you should maintain your position in the right hand lane and retain the right turn signal, until such times as you have reached a position, where you have driven past the exit of the road, before the one which you intend to leave by, at which times you should check both the interior and left door mirrors, before giving a left turn signal, prior to changing hack over to the left lane, to leave the roundabout by the next exit. You should retain the left turn signal, until such times as you have completely cleared the roundabout.

Larger Roundabouts

You will in some locations, encounter roundabouts where there will be five or even six roads entering the roundabout, which may be joining at all sorts of different points on the way round the roundabout. In such circumstances, lane discipline and correctly signalling becomes even more important. You should pay particular attention to the location of the intended exit, in respect of its di¬rection in relation to the road from which you are joining, and also the number of exits, which you will require to drive past before leaving the roundabout. In general terms, turning left at the first exit, is exactly the same as at any other roundabout. However, when the second or third exit, is located before a twelve o'clock position, you should treat both of these exits in the same manner as that required for going ahead at a conventional roundabout, by not signal¬ling on approach and by giving a left turn signal, after the exit before the one which you intend to leave by, where you should then give a left turn signal to exit. When travelling round the roundabout to any exit beyond the twelve o'clock position, irrespective of whether it is the second, third, fourth. fifth, or sixth exit, you should give a right turn signal on approach and maintain that signal. until such times as you have driven past the exit before the one which you intend to leave by, where you should then change the signal to a left turn signal to leave by the next exit.

Spiral Roundabouts

You should be aware of the fact that at an increasing number of larger three or four lane roundabouts. especially where there are additional exits. a spiral flow system may be in operation, where by following the lane markings, when proceeding round to the second, third, fourth, or fifth exit, the lane in which you enter the roundabout, will gradually move further across towards the left and will eventually bring you round to the intended exit, without ever having to change lanes. For example, when going round to say the third or fourth exit, you may enter in the right hand lane of the three lanes, and as you pass the first exit the lane will then become the middle lane and after passing the second, or third exit, it will have become the left lane, which will allow you to reach the intended exit, without ever having to change lanes.

Roundabouts with Traffic Lights

You should be aware that at some larger and busier roundabouts, you may come across some which are controlled by traffic lights, where you must naturally comply with the colour of the traffic lights in the normal manner. On the approach to such a roundabout, you should observe the direction signs for the roundabout on the approach and then look carefully at the various lane markings, which should give you a clear indication as to which lane you should select on the approach. On the approach, you should give signals in ac¬cordance with the intended exit, in exactly the same manner as when you are approaching any other roundabout, however, once you are on the roundabout, it should not normally be necessary for you to give a signal to leave the round¬about, other than in exceptional circumstances, where it has become neces¬sary for you to change lanes. The main reason being that on these occasions traffic waiting to join the roundabout will not benefit from a signal, as they will be waiting for their lights to change to green, before they can proceed. In addition to this following traffic should be aware of your intentions, from the choice of lane which you have chosen to enter and are currently using within the roundabout.

Mini Roundabouts

You should treat the general approach to mini roundabouts, regarding signal¬ling and positioning procedures in exactly the same way as that for a normal conventional roundabout. As the actual traffic island will probably he quite small, which will in most instances mean much less space in which to ne¬gotiate the roundabout, a lower speed than that required to negotiate a larger roundabout will normally be required. In circumstances where a right turn in particular is required, then it is reasonable to expect that much more steering will be required. You should be aware that it this instance, it is much more important to concentrate on the steering, rather than to concern yourself with a signal for leaving the roundabout. In most instances by the time you would have managed to change the signal from a right to a left one, the chances are that you will already be leaving the roundabout, where a left signal given at this late stage would serve no purpose whatsoever. However, it is important that you ensure, that the original right turn signal has been cancelled, before leaving the roundabout.
