Roads: Traffic Lights

Volume 735: debated on Monday 27 February 2012

Question

Asked by

To ask Her Majesty’s Government what consideration they have given to allowing traffic to turn left at a red traffic light in the way that certain authorities in the United States permit vehicles to turn right.

My Lords, we believe it is unnecessary since, unlike in the United States, most UK traffic lights use traffic-responsive systems to reduce delays and improve traffic flow. In addition, the majority of UK signal junctions are provided with pedestrian facilities, which give a green signal only when conflicting traffic is stopped. Any proposal to allow traffic to turn through pedestrian signals would need to resolve the potential for pedestrian safety to be compromised.

I thank my noble friend for that Answer but the position in the United States needs to be made clear. According to the American embassy, ever since 7 December 1975 every state has permitted right turning on red traffic lights with no consequent detrimental effect on safety, and with a positive effect on the flow of traffic and, therefore, on energy conservation. Why can we not try something similar with left-turning traffic lights here?

My Lords, the short answer to the noble Lord’s last point—why can we not try something similar here—is that we believe that it would increase the accident rate. It is very important to understand that the road layout in the United States, particularly in urban areas, is very different from that in the United Kingdom. There is far more space, the junctions are much larger and the cities tend to be laid out on the grid system.

My Lords, does the noble Earl agree that the main difference between the United States and here is that being a pedestrian is thoroughly discouraged in the US? You are supposed to drive around 50 yards if you have to and I do not think that there are any bicycles at all. Given that we have lots of pedestrians and a growing number of cyclists, does he agree that, if anyone is going to turn left on a red light, it would be much better if they were cyclists, if it is to be done carefully?

My Lords, noble Lords behind me are saying, “No way”, and I think they are right. There are already ways of giving cyclists priority over other traffic and improving their safety at junctions—for example, by introducing advance stop lines and cycle bypasses, and providing dedicated traffic signals for cyclists if required.

My Lords, I am sure the Minister will be aware that New York City does not permit the right turn on red precisely because its layout is so similar to the kind that we see in cities and towns across the UK. Having spent many years driving in the United States, in places that permit a right turn on red, I can say that the problem is not traffic. You can see clearly whether traffic is in the way ahead and to the left, but it is virtually impossible to see whether pedestrians are crossing ahead and to the right. Therefore, in support of all those Members who have said that the difference is that we live in a pedestrian’s world, the United States regards pedestrians pretty much as aliens.

My Lords, I am normally in favour of the British public moving leftwards with the greatest possible facility but on this occasion I agree with the Minister. Very serious accidents have recently been caused by large vehicles turning left and hitting either cyclists or pedestrians because their visibility was restricted. As the Minister has indicated, the fact that our junctions are so much more difficult than the grid system in the United States creates an additional danger and disadvantage.

My Lords, although this question refers specifically to the United States, has my noble friend considered the position in France, where the conditions are very similar to our own?

My Lords, if you look at Paris the conditions are more similar but, as I understand it, Paris was relaid out at one point so the road conditions there are different from those in the United Kingdom. In addition, as I said in my initial Answer, our traffic light system is responsive, so allowing left turns would not give the improvements in productivity that you would get in other countries.
