Three of my friends are talking about motorway lane closures. One says in a situation where you are told three lanes are going down to two in a couple of miles you should continue to use all three lanes until the closure and then filter. The other two are adamant that the third lane should be left empty from the point where the closure is announced and that using the third lane is just queue jumping. Friend one says this is just creating a long queue unnecessarily which gets longer and longer with an empty lane getting longer. I don’t drive much on motorways and am just sitting here watching them get more and more heated. What do you think?
